Developer: Elan Homes Project: Phase two of the Redwood Gardens development Cost of build: Undisclosed Location: Marton Moss, Blackpool Type of contract: Private sector Project timescale: Three years Executive summary: Elan Homes is using H+H Celcon Blocks Solar Grade in the construction of its Redwood Gardens development near Blackpool. The inner leaf of 86 new homes will be built using the highly efficient block, the thermal performance of which will help Elan Homes meet its goal of constructing energy efficient homes as part of sustainable communities.
Project description: H+H Celcon Blocks Solar Grade were specified by Elan Homes for the internal leaf of the cavity wall of 86 homes being constructed at its Redwood Gardens development. Situated near Lytham in Blackpool, the 10-acre site was acquired from regional developer, Kensington Developments and forms part of the wider 422-home Redwood Point development at Marton Moss. Phase I of the scheme has been completed and sold, with Elan building the second phase. Elan have experience with timber frame construction but find masonry construction to be more commercially advantageous. The housebuilder signed a Group agreement to use H+H Celcon Blocks Solar Grade as they meet its U-value requirements, enabling them
to build energy efficient homes and help create sustainable communities. Celcon Blocks Standard Grade are already highly thermally efficient, however the Celcon Blocks Solar Grade prioritise combatting heat loss even more so, with a thermal conductivity of just 0.11 W/mK. Using these blocks can significantly reduce the U-values of each house which is important to ensure homes are thermally efficient and perform in line with the latest building regulations. Elan Homes is a growing privately-owned housebuilder, operating across the North West, South West, Midlands and Wales. The acquisition of the Redwood Gardens site marked the start of Elan’s expansion into Lancashire. Construction started in February 2022, with the development expected to be complete by 2025.

Reason for choosing H+H aircrete products: Elan chose to use aircrete rather than dense concrete or other lightweight type aggregate blocks for a number of reasons. Celcon Blocks are lightweight which means they’re easier for bricklayers to handle and lay as there’s less chance of injury. The blocks are versatile for cutting and can conform to many size requirements. They achieve good U-values, ensuring homes are energy efficient, which means homeowners will be saving energy, helping the planet and reducing their bills at the same time.
Products used / aircrete specification: H+H Celcon Blocks Solar Grade were specified for the construction of the inner leaf of the houses. The blocks have a compressive strength of 2.9N/ mm and a thermal conductivity of just 0.11 W/mK. They are also sufficiently loadbearing up to two storeys and can be used below DPC. Celcon Blocks Solar Grade are principally used where enhanced thermal performance is requested or required. Foundations: Due to the ground conditions at the Redwood Gardens site, the homes have piled foundations. External walls: The outer leaf of Elan’s Homes are brick or render. Roof: The roofs are engineered roof trusses. Floor: The ground floor of the homes at Redwood Gardens are constructed using precast concrete block and beam.
Main Contractor comments: “Elan Homes’ company objective is to build homes to meet local housing needs and to create vibrant and sustainable communities. H+H Celcon Blocks Solar Grade meet our U-value requirements under our commitment to deliver energy efficient homes.
H+H comment: “We partnered with Elan Homes in early 2021 and our relationship has gone from strength to strength over this short and challenging period. I hope we can help them grow, having plenty of opportunities with new sites across the country currently in the pipeline.
“The technical support and customer service from H+H is very good. Our rep, Matthew Compton tends to be very hands on and is quick to resolve any issues.”
“It is good to see them taking advantage of our 100mm Solar Grade Blocks to help them achieve the required U-values across all their sites.”

Aircrete is an excellent all round commercial and industrial building material. Used in partition and external walls (both solid and cavity), fire walls and as infill to steel and concrete framed buildings it provides durability, fire resistance and superb thermal and acoustic insulation. H+H aircrete has exceptional sustainability credentials: not only does it provide excellent thermal and acoustic insulation and contributes to air-tightness but, being manufactured from up to 80% recycled materials,
it is sustainable both in manufacture and in use. We also have BES 6001:2008 ‘Excellent’ accreditation for responsible resourcing of materials. In addition, we have an A+ rating under in the BRE green guide on both cavity and solid external walls. Couple this with H+H UK’s rigorous approach to pursuing the highest environmental standards throughout the whole of its business and it’s easy to see why this innovative and award-winning system is now firmly established within the UK.
