CASE STUDIES  

Selected developers who constructed Buildings for 2050 housing schemes and participated in this research project. 

​THE STUDY DEVELOPMENTS 

Picture
The developers had different funding models and a range of drivers for the schemes they developed. They also adopted different approaches to low carbon design. These factors, combined with the variation in tenure, provided a good range of data for the research.

Marmalade Lane, Cambridge 

Marmalade Lane provides 42 dwellings, a mix of flats and houses, with a shared facility ‘Common House’. It deploys a fabric-first design with offsite timber panels for houses and pre-fabricated cross-laminated timber panels for flats. Low carbon features include a triple-glazed panel system, air source heat pumps to supply heating and hot water, and mechanical ventilation with heat recovery.

Team
Developer: TOWN and Trivselhus UK
Architect: Mole Architects
Consultants: Hoare Lea, Elliott Wood, Etude

​Low carbon technology
  • Air source heat pumps (ASHPs)
  • Mechanical ventilation and heat recovery systems (MVHR)

Construction method
Prefabricated cross-laminated timber panels (CLT) for the Apartments. Trivselhus Climate Shield closed timber panels for the houses.
