About the project

Colby Lodge DT Website Inset Image Case Study v1 2The design of Colby Lodge takes many of its influences from the HAPPI Principles, named after the Housing our Ageing Population Panel for Innovation series of reports produced by the All-Party Parliamentary Group (APPG) on Housing and Care for Older People.

Each flat has a 5m2 minimum private terrace or balcony. The development also includes two accessible flats, a communal kitchen, lounge,
therapy room, laundrette and gardens. A sunny sheltered garden, garden room, planted landings within the scheme and individual outdoor spaces encourage social interaction, and provide private spaces for residents.


The building is constructed from loadbearing buff brick and block with precast suspended concrete floors. The third floor is set back from the main façade by agreement with the planning department, meeting their massing needs whilst making efficient use of
the site.

This top floor is framed out in lightweight structural steel and clad in elZinc Rainbow Green vertical standing seam cladding. Balconies and common areas are picked out in perforated aluminium screens. The project also has Photovoltaic panels and a Mechanical Ventilation and Heat Recovery system.

The subtle tonal qualities of elZinc Rainbow Green provides a perfect foil to the highly textured, handmade buff brickwork and the perforated anodized aluminium panels which front the balconies and some of the circulation areas. elZinc is an extremely cost effective titanium zinc product with all the performance qualities you expect, plus a stunning range of colours to meet your design needs.


The project is considered a landmark building – it was opened by local MP Stella Creasy and featured in the 2019 Open House programme. It has also been the subject of several awards including:

  • Housing Design Awards – GLA Award 2019 — Winner
  • Sunday Times British Homes Awards – Best Community Living 2019 — Winner
  • New London Awards 2019 – Health and Care – Shortlisted
