Making a Positive Impact
Welcome to our second Impact Report. This edition reflects our continued commitment to delivering meaningful social and environmental impact— recognising that the wellbeing of people and the health of our planet are fundamentally interconnected.
The context in which we operate continues to evolve rapidly. Climate and environmental pressures are increasingly affecting communities and deepening inequality. Over the past two years, the impacts of climate change have become more visible, while geopolitical challenges have highlighted the global reliance on fossil fuels and the far-reaching consequences this has for people and economies.
Since publishing our first report, we have made significant progress. We have introduced new initiatives, strengthened existing programmes, and deepened our relationships with stakeholders across the communities we work within. We have also improved how we measure and understand our impact, giving us a clearer picture of the difference we are making for both people and the environment.
Against this backdrop, our role is clear. We must continue to deliver low-carbon projects and actively support our clients in recognising the long-term social and environmental value of retrofit solutions. The choices we make today will have lasting implications for both people and the planet.
Key developments since our last report include a stronger focus on employee wellbeing, supported by a dedicated Wellness policy and a network of Wellness Ambassadors. We have also introduced new policies on Menopause and Gender Reassignment, alongside more inclusive, family-friendly initiatives, including an industry-leading maternity package. To reinforce transparency and accountability, we have introduced an independent whistleblowing service, WhistleB, strengthening our commitment to the highest standards of integrity.
While we are proud of the progress we have made, we know there is more to do. Adopting the most sustainable pathways remains a key challenge, as does ensuring we engage and support harderto-reach groups so that the benefits of our work are shared more widely and equitably. This report sets out not only what we have achieved, but also what we are learning and where we must go next. We remain committed to continuous improvement, transparency, and delivering lasting impact for the communities and environments we serve.
Environmentally, we have achieved an important milestone by reducing business mileage by 10% against our 2022 baseline, whist also improving the quality and scope of our commuting data. Beyond our organisation, we have expanded our community reach, creating opportunities for more young people and strengthening our contribution to the places and communities we serve.

Governance At Corstorphine & Wright, our mission extends beyond profitability. We aim to shape a world where architecture acts as a catalyst for inclusion, opportunity, and positive change. Diversity and equity sit at the heart of our vision, guiding how we design, collaborate, and contribute to the built environment. To deliver this, we cultivate a strong and supportive culture, underpinned by effective leadership, meaningful engagement, and clear, measurable outcomes aligned with our strategic objectives. Our dedicated Head of ESG, supported by an ESG Steering Group, drives our environmental, social, and governance agenda. Together, they provide clear direction and accountability, enabling us to continually enhance our environmental performance, social impact, and governance standards in line with sustainable business practices. We actively promote open communication and collaboration through our intranet and colleague led forums, including our Sustainability Champions, Social Impact and Wellbeing Ambassador networks. Monthly in-studio breakfasts and stand-up meetings help reinforce our One Practice culture, providing space to share updates, exchange ideas, and ensure every voice is heard. Our commitment to inclusion is reflected in our ongoing Diversity & Inclusion initiatives and our focus on improving gender balance, supported by a clear Gender Pay Gap Action Plan. Through these efforts, we are working to create a more inclusive, equitable, and forward-thinking architectural practice. One which opens doors and creates opportunity for all.

A FRAMEWORK FOR MEASURING OUR IMPACT | DE&I KPIS
Over the past 36 months we have taken a structured approach to narrowing our gender pay gap, focusing on improving representation, progression and workplace culture. Key initiatives include enhanced family-friendly policies, such as extended maternity and carers’ leave, alongside the introduction of transparent promotion processes, mentoring programmes and leadership training to support career progression. We recognise there is further work to do. We’ve also strengthened our commitment to an inclusive culture through mandatory training as well as a formal code of conduct and improved reporting mechanisms. We are delighted that these actions are beginning to deliver measurable impact, with an increase in women in senior roles and a notable reduction in both median pay and bonus gaps; however, we recognise that this takes time and there is further work to do.”
Michael Walters, Group Director, Corstorphine & Wright

Family Friendly Policies We understand that colleagues are at different stages of their lives, and our Family Friendly Policies are designed to support them through key life events: •
Enhanced Maternity and Adoption Leave gives 39 weeks of full pay to mothers and adopters with over five years’ service. We have introduced a Maternity Buddy scheme, a parental pack, and back-to-work inductions to help parents return after family growth.
•
Carers’ Leave gives one week of full pay to support colleagues caring for elderly parents, a sick spouse, or a disabled child.
•
Bereavement and Terminal Illness Support offers colleagues support with dealing with a bereavement or terminal illness.
•
Westfield Health cashback scheme covers all employees and their dependants. The scheme offers cashback on healthcare, 24/7 GP access, therapies, gym discounts, and shopping offers.

Health & Wellbeing We are committed to maintaining a workplace culture that prioritises wellbeing, inclusivity, and support for all colleagues. To enhance this commitment, we have established a Wellness Network, a collaborative initiative comprising Mental Health First Aiders (MHFA) and Wellbeing Ambassadors. These passionate individuals champion positive wellbeing across our studios, ensuring colleagues have access to the resources and support they need. While Mental Health First Aiders have received specialist training to identify, listen to, and assist colleagues experiencing mental health challenges, Wellbeing Ambassadors focus on promoting all aspects of wellbeing , including physical, social, financial, and emotional health to ensure a holistic approach. Our Employee Assistance Program (EAP) offers all colleagues a counselling service from a team of accredited counsellors available instantly via live chat, video call and the 24/7 hour helpline. Unlike many helplines, the EAP is not just here for life’s crises. Everyday issues such as the stress of moving house, managing money, illness or injury or returning to work after a break can raise questions or concerns that may benefit from a conversation.
A FRAMEWORK FOR MEASURING OUR IMPACT
Community We focus on practical, community-led activity that delivers tangible benefits for the people and places we work with. Our aim is to support wellbeing, create opportunities through our stakeholder relationships, and contribute positively to local communities. Our Practice Social Impact Team brings together 22 colleagues from across our studios, each bringing experience of working with schools, local employment partners, charities and community groups. The team helps coordinate initiatives, share good practice and encourage participation across the Practice. By working with local organisations and listening to community priorities, we aim to ensure our activities respond to genuine needs and deliver value where it is most needed. The approach also gives colleagues opportunities to contribute their time, skills and ideas in ways that complement their day-to-day work.

A FRAMEWORK FOR MEASURING OUR IMPACT | COMMUNITY
Community Initiatives Plan (CIP) The CIP is our way of doing more, and doing it better, by starting with what matters locally. It’s built from the ground up by our Social Impact team, working alongside colleagues in each studio to identify local needs and the causes and community activities they want to support. These range from small, hands-on initiatives to longer-term partnerships — from litter picks and local volunteering, through to involvement in events like St Basil’s Sleepout and Pride in Birmingham, and supporting organisations such as Women’s Whispers, Holbeck Together in Leeds, and Gateshead’s Uniform Scheme through our Newcastle studio. Over the past two years, the CIP has driven a marked improvement in our studios’ social impact ambitions and broadened the range of initiatives they undertake. Most importantly, it is enabling us to deliver greater positive impact by focusing on what our studios themselves have identified as the most pressing needs within their local communities. We track CIP activity so studios can understand their contribution, strengthen relationships with community partners, and set clear, realistic goals to grow their impact over time.

Educational Engagement Engaging with students of all ages sits at the heart of our Social Impact work and ambition. We are continually developing how we work so we can do more, do it better, and create lasting change in our local communities—especially for those who do not typically see themselves represented in our profession. Through our ‘Opening Doors’ and ‘Widening Participation in architecture’ commitments, we partner with universities, colleges, and primary and secondary schools across the UK. Every studio works with at least one Partner School, providing design support across Key Stages, careers guidance, mentoring, and work placements (a minimum of four per studio each year). We focus on building long-term relationships with Partner Schools and their students, particularly those who complete work placements with us. We offer practical support, skills development, mentoring, and access to employment opportunities, helping to broaden access for students who may not have the networks or support others can rely on.

Our Partner Schools are local to our studios and are selected based on clear need: •
Rated ‘Inadequate’ or ‘Requiring Improvement’ by Ofsted
•
Among the lowest attainment levels in their area
•
Highest percentages of students receiving Free School Meals
Since our last Impact Report, we have expanded our support to include T Level students and have worked with partners including Ruskin Mill College and Child Autism UK to provide work experience for neurodiverse students. This has delivered strong outcomes for students and helped our colleagues build greater understanding and awareness. We continue to support architectural students throughout their studies by employing them from their second year at university and supporting them financially through their professional development. Working across a range of projects gives them varied experience and a strong portfolio, helping them stand out as they progress in their careers.

Partnerships
We’ve always believed we achieve more by working together, and over the past two years, we’ve deepened our partnerships to deliver more meaningful support. By collaborating with organisations that share our values, we’re reaching more people and making a greater impact. Our partnerships with Women’s Whispers and Holbeck Together have continued to grow, supporting more people with essentials such as food parcels and clothing, as well as community initiatives like local clean-up projects. Alongside this, we’ve continued to build relationships with organisations including Clervaux Trust / Ruskin Mill College, Red Sky Foundation, Child Autism UK, and Kettlebrook Short Stay School. These partnerships have broadened how we support individuals and communities, ensuring our work evolves in response to real needs while staying focused on those facing the greatest barriers. This approach has strengthened our impact, enabling us to reach a more diverse group of people and making our commitment to widening participation clearer and more accessible.

Unusual HQ is an exceptional example of what a modern workplace can be — achieving an EPC A+ rating and significantly surpassing LETI/RIBA 2030 energy targets through low-energy design, climate resilience, and a strong focus on embodied carbon reduction. Its performance has been driven by biogenic materials, extensive reuse, and a design approach centred on disassembly and long-term adaptability. The impact of the building is felt not only in its environmental performance, but also by our team who work within it — with one team member describing it as ‘like joining a cutting-edge company without even having to interview for the role.” Tom Harper, MD Unusual Rigging

Advocacy Reducing carbon emissions requires collaboration across the built environment. We actively share knowledge and promote best practice with colleagues, clients, consultants, suppliers and industry partners. During 2024–25, this included speaking at UKREiiF, Futurebuild, Women in BIM, Bisnow Life Sciences and the Innovation Real Estate Annual Conference, alongside thought leadership contributions to the AJ and Property Week. Two members of our practice sit on NLA Expert Panels, helping shape discussion around London’s built environment while bringing emerging thinking back into the practice. In September 2025, Director Jonny Plant was appointed Chair of the NLA Circular Economy Special Interest Group, enabling us to contribute directly to the development of circular economy best practice across the sector. The role also provides early access to emerging policy, innovation and industry best practice, strengthening our expertise and informing the sustainable solutions we deliver for clients.

Managing Our Design & Operational Emissions We continue to strengthen the way we measure and manage our environmental performance. Annual reporting and regular reviews provide the ESG Steering Group and Board with clear oversight, while our in-house Studio Environmental Tracker captures operational data across energy, water, waste and resource use to support informed decision-making. Environmental performance is embedded throughout our design process using circular economy principles and a whole-life approach that considers embodied carbon, operational carbon, material selection and future reuse. This information is collated, tracked and monitored through our quality management and environmental system, providing a consistent framework for measuring performance, informing decision-making and driving continuous improvement. Working closely with our supply chain also enables us to improve emissions data quality and identify opportunities to reduce environmental impacts collaboratively.
ISO 14001 Operational Environmental Targets include:
REDUCE
INCREASE
Business miles
Recycling of operational waste
Number of plane journeys
Use of renewable energy
Waste
Use of recycled equipment
Paper, printer ink etc. usage
Use of most efficient electrical equipment
In addition to the above, we introduced in July 2022, the following carbon saving initiatives:
A Practice wide salary sacrifice scheme for electric vehicles
Refurbishment of several studios to include more LED lighting and improved air quality through biophilic design
Extension to our ‘Cycle to Work Scheme’ to include access to electric bikes
A FRAMEWORK FOR MEASURING OUR IMPACT
Carbon Reduction Plan Our Carbon Reduction Plan (CRP) establishes the governance framework for reducing operational emissions while supporting compliance, improving resilience and demonstrating progress to clients, investors and other stakeholders. As our reporting capability has matured, we have refined the plan to improve the quality, transparency and consistency of emissions data. Progress is being driven through our Low Carbon Studio initiative, supported by targeted measures including an Electric Vehicle salary sacrifice scheme, a transition to renewable electricity, reduced business travel, and increased operational recycling Having exceeded an interim environmental milestone for business miles at the end of 2025, we remain focused on achieving our commitment to reduce operational emissions by 30% by 2027.

Sustainable Design Sustainability Champions Our Sustainability Champions, drawn from a range of roles across the Practice - have responsibility for increasing their skills and expertise and cascading these into their studios through active promotion and knowledge sharing within each project team. Their active participation is part of a structured multidimensional approach to embedding sustainability throughout the design process.
Sustainable Design Ethos (SDE) Our Sustainable Design Ethos is a concise framework for delivering sustainable, resourceefficient buildings grounded in Circular Economy principles. The SDE strengthens sustainability performance across the organisation and with clients by providing both advocacy and guidance. It ensures all teams apply consistent design standards, enabling projects to meet Net Zero Carbon targets and reinforcing our commitment to high environmental performance.
Developing Capability Our network of Sustainability Champions brings accredited expertise in areas such as BREEAM, Passivhaus, WELL and Retrofit, and share knowledge across studios and project teams. This practice wide group remains central to embedding best practice and driving continuous improvement on our journey to Net Zero. To achieve Net Zero, we will continue to strengthen our sustainability capability through the use of innovative, industry-leading software and digital tools that enable robust whole-life carbon analysis across all projects, alongside promoting a fabric-first approach. We actively advocate for high performance, low carbon buildings and deliver them through our Sustainable Design Ethos. We strengthen our capability by reflecting on our work, learning from experience, and applying those insights to continuously improve.
Stage 0-1 Strategic definition preparation & briefing
Our Commitment To effectively tackle the climate challenge in the built environment, our approach centres on a collaborative, multifaceted, and holistic strategy. Our commitment to sustainability is embodied in the Climate Framework Initiative, a unified effort supported by the Cross-Industry Action Group, RIBA, UKGBC, LETI, and other esteemed professional bodies, membership organisations, and academic institutions. This initiative represents a concerted effort to mitigate climate change and ecological degradation. Our commitment to creating genuinely sustainable environments involves addressing climate challenges within the specific social, economic, and environmental contexts of each project. Our Sustainable Design Ethos (SDE) is anchored in six key themes: Human Factors, Circular Economy, Energy & Carbon, Water, Ecology & Diversity, and Connectivity & Transport. By embedding these principles into our approach, we ensure that our designs not only address the impacts of climate
Certification change but also actively contribute to resilient, thriving communities. This holistic approach balances social equity, economic viability, and environmental stewardship.

A FRAMEWORK FOR MEASURING OUR IMPACT | SUSTAINABLE DESIGN
Circular Economy We have been actively embedding Circular Economy (CE) principles into both our operations and building design, recognising that this is essential to achieving our Net Zero goals as well as the right way to design. Our Sustainability Champions play a key role in driving this forward, embedding renewable materials, modular thinking and design-for-disassembly strategies across projects. A major step forward has been the award-winning Unusual Rigging Headquarters, which provided a real-world example of circular, low-energy design. The project helped us explore new approaches and materials, and we are now applying these lessons to embed circular economy principles more consistently across our work, moving away from linear approaches towards more regenerative design.
Unusual HQ in Northamptonshire Unusual HQ in Northamptonshire, home of lighting and stage engineering solutions provider Unusual Rigging, took home two BCO National awards in 2025 - for ‘Corporate Workplace’ and the ‘Best of the Best’. The project was given the awards for not only achieving the very highest energy performance rating of EPC A+ and being built entirely on circular economy principles, but for exemplifying how modern offices have evolved to become beacons of sustainability best practice. A key highlight for judges was how this innovative building could be disassembled and reused at the end of its life, massively reducing its carbon footprint.

In designing Dorset Police’s New Headquarters, Corstorphine & Wright completely understood the brief which was to put the welfare of its people at the heart of the design. The building provides a range of settings to support our Hybrid working ethos, it’s refreshingly light and modern but also practical and deceivingly spacious. C&W’s recommended finishes exudes quality and expertly blends style with operability. As the client PM, one of the most valued aspects of this contract was the importance C&W placed on forming a good working relationship with me so that at every stage I felt prioritised. I have been professionally guided through the complexities of each of the RIBA stages and without exception, C&W have approached requests for change positively, resolving design conundrums with imagination and flare. Importantly even after novation, C&W continued to protect the integrity of design on my behalf, the resultant building is a spectacular example of C&W’s talents and commitment to excellence.” Selene Cooper Dorset Police Project Manager

We at Moss side Millennium Powerhouse are thrilled with our partnership with Corstorphine & Wright. They have been crucial in bringing the expertise necessary for our Decarbonisation project. The Project is a challenging one due to complex relationships with the Local Authority, the funders and a multi-purpose large building which needs to remain open throughout the programme. The government funding also has tight constraints and has layers of external involvement. It is a 3 phase programme, with the first phase fully funded at £2.4 million. We will continue to work with them and secure funding for the next phase. The project is well underway, and they have advised and assisted every step of the way to ensure we have the correct team, contractors, and expertise. Their social value commitment which involved working with Manchester School of Architecture students has been important and was well received.” Lisa Davenport CEO, Moss-side Millenium Powerhouse

Womens Whispers
Corstorphine & Wright have been outstanding in all the genuine support shown to Women’s Whispers. As one of their chosen charities, Women’s Whispers CIC has really benefitted from the corporate compassionate initiatives C&W have given our ethnically diverse survivors of domestic abuse benefit. This is crucial as they experience language, access, and honour barriers. As we are unfunded this support is crucial for us. (With regard to)… the recent Iftaar event - organised by Muneebah and team - I was invited to speak about Women’s Whispers. I was blown away by the organiser’s thoughtful and inclusive event to share and celebrate a key faith event. The staff all fasted and opened their fast together at Iftaar with a delicious buffet meal. This not only raised awareness on the purpose of fasting, but staff practically fasted too. The money collected was kindly donated to Women’s Whispers. Jenna regularly collects good quality items from the team to donate to us. These items are a lifeline for survivors of domestic abuse. C&W have truly demonstrated their social values are not just a written policy but practically support ethnically diverse communities who slip through the nets and are in crisis and destitution. Thank you for all you do to support Women’s Whispers.” Sunjeeda Hanif Womens Whispers

Work Experience
Thank you so much for opening the doors at Corstorphine & Wright for Daniyaal to attend work experience. Daniyaal had an exceptional time considering he has a diagnosis of autism and panic disorder. Corstorphine & Wright, Muneebah, and the whole team at your Leeds office made the impossible possible. On the third day he messaged me and said: “Mum I want to stay, pick me up later.” I cried hearing that ……he had originally been psychologically distressed being there due to social and sensory overexposure…. masking his distress to fit in. Muneebah actively listened and ensured adaptations were made to accommodate his disability needs…. resulting in him managing his reluctance and easing in slowly. Tyler’s gentle mentoring alongside Muneebah’s also made it more acceptable and enjoyable for Daniyaal. As a parent and carer I cannot thank you enough for demonstrating (how) Corstorphine & Wright fully supports the needs of autism to ensure children get the opportunity to explore this field and fully receive a holistic work experience. The outcome of his work speaks volumes itself about his ability. Your silent reviews made it so exciting for him to read the feedback. This was a gamechanger in ensuring inclusivity again, thanks for thinking of this, Muneebah. Daniyaal has been so proud and created a portfolio for this piece of work exploring architecture. Thank you again to the whole team and if you have any opportunities where Daniyaal can come in again he will happily come back. Warmest wishes and thanks again.”

Community Engagement
We place considerable importance on involving the local community from the very earliest design stages, ensuring developments are shaped by the people who know these places best. On our projects at the Swan Centre and Upper Trinity Street, we worked closely not only with key stakeholders but also with local residents—and, at Trinity Street, with local artisans and creatives—to ensure their voices were central throughout the process. This collaborative approach means that community aspirations directly inform the design, helping us preserve what makes each area unique while delivering meaningful regeneration. Our engagement went beyond standard public consultation to include a mix of accessible, inclusive activities, including in-person exhibitions, online events, webinars, and targeted outreach to reach underrepresented groups. For the Swan Centre, a Community Design Review Panel was established enabling local people to play an active role in shaping the evolving proposals. Progress was shared transparently through newsletters, website and leaflets, keeping the community informed and involved at every stage.

Making a Positive Impact
GOOD THINGS ARE HAPPENING HERE
Over the past year, Corstorphine & Wright’s partnership with Nyami Studio has continued to develop, reflecting a shift from initial alignment to sustained project delivery and increased organisational engagement. The relationship has strengthened through ongoing financial support, technical collaboration, and broader staff involvement across the practice. A key milestone during this period has been the advancement of Lolo’s Library in Adams, Philippines. The project has progressed from design development into the construction phase, representing a significant step in the delivery of Nyami Studio’s international portfolio. Located in a region where adult literacy rates remain comparatively low, the scheme has been developed to respond directly to local need, providing accessible educational facilities and community learning spaces. The library is designed not only to improve access to educational resources, but also to support long-term learning outcomes, while demonstrating the application of low-carbon construction principles using locally sourced materials. Corstorphine & Wright has maintained an active role in supporting the project, providing continued financial contributions alongside design and technical input. In parallel, employee engagement has increased, with a growing number of staff contributing their time and expertise to support project outcomes and knowledge exchange.
