We are an award-winning architecture practice founded in 2013 by Darren Oldfield. We design and deliver bespoke, carefully crafted buildings, responsive to the brief and budget of our clients, their environment, and their context. Natural light, volume and space are our key design principles. We emphasise sustainability and quality of life in every project.

About Darren I have worked in architecture and construction for over twenty years. Architecture has always played an important role in my life: my father is an architectural designer, and I spent my teenage years learning the trade with him. Sustainability and sensitivity to the client’s brief and budget are foremost in my approach to architecture. Before establishing my own practice, I worked in award-winning architecture firms across the country, including marsh:grochowski in Nottingham and Cowper Griffith Architects in Cambridge. I qualified as an Architect in 2009, receiving my Masters in Professional Practice (Merit) from the University of Nottingham. Before that I received my Diploma in Architecture (Distinction) also from Nottingham, and my BSc (First Class Honours) in Architecture and Environmental Design from Sheffield Hallam University.

shakespeare road

The property: typical Victorian London terraced house in Herne Hill The brief:

to design a contemporary wraparound extension and mansard loft conversion

Year:

2017

The solution: We reconfigured and extended ground floor space to create an open plan kitchen-dining area, utility cupboard and cloak room. The space features a dramatic 9m long rooflight connected with an oriel window which looks out to the garden. The striking rear elevation used an anthracite grey zinc cladding, and the patio was finished with a clay herringbone paver, matching the pattern of the floor finish internally. In the loft, we created a stunning master suite with individual vaulted ceilings in each space. A bespoke timber staircase echoes the details of the existing house but created a light-filled two storey void. Elsewhere in the house we altered the hallway for improved circulation, upgraded the heating & AV systems, and completely redecorated the house. Partners:

“If we’d gone with the original plan, then our house would have been bottom heavy and with less garden space. Our new scheme is much more balanced. I’m really pleased with Darren’s attention to detail and we love living here.” 07

upland road The property: 19th Century villa in East Dulwich The brief:

to design an imaginative solution to a cramped triangular site, providing additional living

space on the ground and first floors

Year:

2015

The solution: The villa’s peculiar narrow gable provided a key first clue to the form of the addition. A lower level of stock brickwork provides a plinth to a scaled down version of the existing villa gable, re-imagined in a strippeddown contemporary material palette. The reconfigured ground level provides a kitchen-dining room at the rear of the house, making the most of the available afternoon sun. Adjacent to the kitchen, a study-guest bedroom links to a hidden side garden, while a family bathroom and third bedroom completes the extension at first floor level. The upper floor is thoughtfully designed to maximise light from glazing above and oblique windows to the sides, which avoid overlooking neighbouring properties. Despite the constrictions of the site, and an earlier planning refusal, the scheme sailed through planning in June 2014. Work started on site in January 2015, finishing in five months. Partners:

choumert house

The property: modest Victorian mid-terrace in South-East London The brief:

an ‘out-of-the-ordinary’ single-storey wraparound extension to transform the dark, low-ceilinged

kitchen, with exterior landscaping and a full refurbishment of the property

Year:

2019

The solution: Our clients had previously dismissed a project by another firm for which they had obtained prior planning permission. We created for them a spacious, pared-back aesthetic which seamlessly links indoor and outdoor spaces through a material-led, “outside-in” design. We aimed to combat the darkening effect of the high walls and tree-lines either side of the property by maximising height and light. The material palette of cast concrete, charred timber cladding and reclaimed London brickwork is designed to sit discreetly within the urban environment. Interior exposed brick and exterior paving create flowing relationships between inside and outside. To the exterior, concrete, zinc and charred timber cladding sit calmly within the facade, leading to wood-free, sustainable decking that mirrors the muted colour palette. Careful attention to the choice of materials and their layout give an overall impression of pared-back simplicity. Partners:

streatham townhouse The property: late Victorian townhouse in Streatham The brief:

complete refurbishment of entire ground floor, with a contemporary rear extension, front and

rear landscaping, and a fabulous studio at the foot of the garden

Year:

2017

The solution: The extension is a subtle combination of Danish brick, bronze glazing, exposed timber and terrazzo flooring. The use of the brick on internal walls and the large expanses of glass help to blend the new extension with the contemporary landscaping in the garden beyond. But the serene finished space sits above complex engineering and ground works that lie beneath. Our detailed survey uncovered a mainline Thames Water sewer that runs adjacent to the site, which could have significantly limited the size and scope of the planned space. Overcoming this obstacle took some creative collaboration with our structural engineers. Together we developed a series of deep piles and a cantilevered ground floor slab, creating a stable platform on which the extension sits without disturbing the existing sewer system. Our clients were so delighted with the result that they commissioned us to design a striking studio space/garden room at the end of the rear garden.

oglander road

The property: generous Victorian semi-detached house in Peckham Rye The brief:

to transform the ground and first floors, including a full width rear extension, and full

refurbishment throughout the rest of the house

Year:

2017

The solution: Planning restrictions placed strict limits on the overall height of the extension to this house, but we used our creative design skills to turn this initial limitation into an advantage. At the point where the older part of the property meets the new, we designed a clerestorey window to run across the full width of the building. This throws light back into the room, ensuring a sense of spaciousness throughout. The clerestory gives onto a wild-flower roof installed in the extended part of the house, just visible as you enter the living/dining space from the refurbished front hallway. Reclaimed London brick creates a textured facade with depth and interest, while the pair of pocket doors that open out to the rear garden are another unassuming design detail. Rather than following the more commonly used bi-fold system, these rear glazed doors slide back into the wall itself, maximising the sense of space and connection to the outdoors. Our clients had briefed us about their problems with noise transfer: we improved this using innovative spray foam insulation between walls. To create a comforting home atmosphere we also installed a wood-burning stove and bespoke joinery in the front reception room, and on the first floor reconfigured the family bathroom into a master suite with bespoke joinery.

pine walk

The property: generous modern detached property in Carshalton, built in 1998 - a refreshing break from

working on Victorian houses!

The brief:

a contemporary set of extensions to a very brown house, to create a much bigger kitchen-dining

space, garden room, and attic guest bedroom suite

Year:

2019

The solution: The scheme uses a rich palette of coloured zinc, dark Danish brickwork, and handmade clay tiles. Ultra-thin profile sliding glazing on the ground floor maximises light and puts the view of the garden to its full advantage. We also partially converted the double garage into a play room and outside storeroom. The loft conversion posed a particular challenge to our design and engineering skills. The unassuming-looking result required 3 tonnes of steel to strengthen the original trussed rafter roof, and created a beautiful guest bedroom and en-suite bathroom. The loft’s up-and-over glazed window sits above the staircase and lines up with a matching rooflight to the front of the property. These innovations are typical to our design process, which aims to work harmoniously with the needs of the client, the structures of the original building, and the engineering required to deliver the design.

orleans road

The property: end-of-terrace Victorian property near Crystal Palace The brief:

to refurbish and reconfigure the house, without extending

Year:

2018

The solution: Our main challenge was to meet our clients’ brief of opening out and expanding the space, without extending. The pre-existing house did not really meet with the needs of this young family. Its smaller interlinked rooms backing onto the rear garden had limited use, and made their home feel unnecessarily cramped. Without extending the original footprint of the house, we developed a series of interventions to open the house up to its outside environment, as well as its interior. The resulting light-flooded open-plan kitchen, living and dining area is connected to the garden via a series of bespoke timber sliding doors, adding a soft, Scandinavian touch. The refurbishment we put in place in the rest of the home sustains this assured, understated aesthetic. Sympathetically designed bespoke joinery can be found throughout the client’s new home, from the utility to the living room. Our intelligent storage solutions maximise space and create a sense of calm comfort. This is a home we’d love to live in ourselves. Partners:

art deco house The property: a rather special property in a set of six similar art deco-inspired houses from the early 20th

century, located in South East London

The brief:

to completely renovate the property and increase living space on the ground floor

Year:

2018

The solution: Working collaboratively with partner practice KN Designs, we developed proposals for a rear extension with a curved brick facade featuring a central glass window/rooflight. Symmetrical design and simple brickwork details echo the original Art Deco period of the property, without attempting to copy it. We retained the separating wall between living and kitchen spaces, while extending the floor area beyond them to create new open-plan dining and play areas. Inspired by the circular drawing room at Eltham Palace, symmetrical circular skylights draw in natural light from above, echoing the curves in the new rear facade. Crittall window and door glazing creates two openings onto the expansive rear garden, and the wooden parquet flooring throughout retains the mid-twentieth century appeal of the home. Discreet bespoke joinery throughout keeps a sense of clean finish, while providing useful storage solutions for our clients’ busy family life. Partners:

ryedale

The property: 19th century terraced house in East Dulwich The brief: A partial house refurbishment and loft conversion Year: 2016 The solution: We were appointed by the owners of this lovely terraced house after their first architects failed to deliver the wow factor. The house has a wide footprint but was compromised by the first floor layout and relatively low ridge height in the loft. We re-arranged the first floor, creating a new family bathroom at the rear and a doubleheight circulation space with built-in study and storage units. We maximised the loft width by installing a full width window, helping to offset the lower head height. The rectangular panes of traditional steel Crittall windows give panoramic views of the trees in Camberwell New Cemetery beyond. Elsewhere we stripped & refinished the flooring, knocked through the living room and dining area, and redecorated. The external joinery is now charcoal grey, matching the new windows. We also designed fitted furniture to make the most of every nook and cranny. When our clients sadly decided to move on, estate agents valued the house with one of the highest ÂŁ/m2 rates in the postcode. This is a testament to the value we bring to our clients, as is the fact that they are looking to work with us again on their next property. Partners:

We always present initial sketch designs in person to explain the scheme and answer your questions. We follow up with revisions responding to your feedback. Most projects require just one or two revised designs to get it right.

4. working drawings

Once planning consent is secured, we prepare all the necessary construction information for a contractor to carry out the work. We consider all elements of the construction process to mitigate the risk of problems arising on site. For the project illustrated here, we prepared around 40 drawings for the building contractor. We also assemble the wider team of consultants needed to develop the design. This will vary between projects, but can include a structural engineer, interior designer, party wall surveyor, AV & lighting consultants, and landscape designers. We partner with trusted consultants and can make recommendations in most instances. We co-ordinate with the whole design team to ensure that all build components fit together correctly. We provide internal layouts of key spaces like kitchens and bathrooms, as well as electrical and lighting layouts. We also prepare designs for bespoke fitted furniture, such as wardrobes, home offices and entertainment centres.

We work with you and/or your interior designer to ensure that your choices for interior finishes, fixtures and fittings co-ordinate with the rest of the build. The more decisions you finalise before work starts, the more quickly and straightforwardly the build is likely to progress. Once the drawings are complete, they are issued to contractors for pricing. We are happy to guide you through the procurement process and to discuss your best options with you. There are two potential routes for this. The first is formal tendering: each individual element is priced by each contractor, and overall costings compared for quality, thoroughness, accuracy and competitiveness. The second is where we assist you in negotiating an overall price with a single chosen contractor. We can make recommendations for contractors with whom we already have strong professional working relationships, but we are always happy to consider highly recommended builders you may know about from friends and family.

5. site supervision

In our final work stage, we assist whilst the project is on site. We call this site supervision, and we undertake several key activities for this stage of work: Contract administration We ensure that both you and the contractor are fairly represented under an industry-standard contract by acting as contract administrator. To guarantee that you are not being overcharged at any point during the work, we issue regular certificates to verify that sums requested by the contractor are correct. We certify when the work is complete, and when all final defects have been addressed. Site inspections We regularly visit the site to meet with you and your contractor, to ensure that our drawings are being implemented correctly, that the workmanship is of a good quality, and to deal with any surprises that pop up along the way. Generally we will visit every two weeks, but this can be more frequent at key stages. There are some key things that we are not responsible for when your project is on site: Programming is the responsibility of the contractor The contractor will set a programme at the beginning of the contract and is responsible for organising materials and labour to adhere to this. The contractor is responsible for the day-to-day programme management of the build. We have very limited control over the detail of the programme, but we can extend the programme length under certain circumstances. Client supply items are the client’s responsibility You are responsible for ordering a range of items and ensuring that they are received on site. This usually includes your kitchen, bathroom fittings, floor finishes & tiles, light fittings and ironmongery. Delivery needs to be timely for the builder to incorporate these items at the right point in the build. We will help you so that you know which items you need to buy, and the building contractor will let you know when they need them. It may seem daunting to take responsibility for these items: we offer advice and have drawn up a document that specifically outlines what you need to do. For larger projects, it can be helpful to employ an interior designer to co-ordinate and order larger client supply lists.
