Location: Woodford Green
Sector: Affordable Housing
Client: London Borough of Redbridge
Value: £400,000
Duration: 48 weeks
Completed: November 2016

This PassiveHaus project was a first for both the London Borough of Redbridge and ourselves, with very onerous design and construction issues that needed to be taken in to consideration throughout the project from conception through to completion to adhere to the PassiveHaus design criteria.

The project was built on an underused garage site consisting of three terraced houses built to PassiveHaus standards which incorporated a timber frame with increased wall thicknesses and greater levels of insulation being constructed to strict air tight details, external facades of face brickwork and render, pitched tiled roof with inset PV panels, triple glazed UPVC windows and doors and a centralised Mechanical Ventilation and Heat Recovery System all contributing towards lower U/values and better energy efficiency in the completed houses resulting in A rated EPCs and offering a saving in the region of 30-40% on the average annual running cost of a new home.

The external design included a private driveway leading to parking for 4 cars and gentle sloping paths giving access to both the front entrance doors and large gated rear gardens for each of the plots each laid to lawn with generous paved patio area.

In addition to being built to PassiveHaus standards the project was also designed to fully comply with the London Plan Policy, Code for Sustainable Homes, Secured by Design and Lifetime Homes incorporating details such as secure bike storage within the garden shed, level access thresholds to both front and rear doors for wheel chair access, downstairs WCs and future hoist routes designed into the timber frame to give full accessibility within the house and PAS24 window and doors for added security.
