CLIENT: United Communities
PARTNERS: Baker Ruff Hannon, SE3 Design, Barnaby, Hydrock
LOCATION: Land Bounded by Winterstoke Road, Luckwell Road & Lynwood Road, Bristol BS3 3HH


Real is working in partnership with United Communities to deliver 67 new units at Luckwell road. The existing buildings will be demolished and will be replaced with 8no terraced houses and 59 one and two-bedroom flats.

Close to Parson Street station, the new homes will be arranged over three blocks with the tallest block standing at five-storeys. The site is surrounded by three roads: Winterstoke Road, Luckwell Road, and Lynwood Road. Each block built will be named after each of these roads.

All of these homes will be built to passivhaus standards through the use of Porotherm blocks for the structure of the blocks.

The development will also feature an area of public open space which will include a children’s play area, car parking areas, cycle storage, bin stores, and amenity space.


  • Base levelling course – As porotherm is a thin joint construction method it is essential that the base levelling course is as accurate as possible in order to achieve this we allocated more time for the trades to install this and a higher level of supervision/checking during this phase than would normally be allowed.
  • Renewable energy – Based on the requirements for renewable energy strategies it was decided that ground source heat pumps would be the preferred option due to improved efficiency and the level of grant funding available.
  • Early engagement - Due to the level of information required to achieve passivehaus certification we engaged the assessor at stage 4 design, this ensured that the information being produced would fulfil the requirements of the assessment prior to construction.
  • Combined air seal/gas membrane – Although it is technically feasible for the gas membrane to be laid on top of the structural slab this causes weak points in relation to airtightness when trying to achieve passivehaus. Due to this, we worked with our designers to produce a under slab solution which resulted in a continuous air seal to the entire building structure.
  • Protherm and scaffolding – As porotherm blocks are lighter and quicker to lay, the challenge is ensuring that the access arrangements can be maintained to maximise the benefits of production rates. To resolve this we opted for a free standing external scaffold erected a minimum of 2 storey’s above prior to commencing works and then a Rhino deck as the internal crash deck and access, this way we maintained the access without effecting the laying teams output.
