SUSTAINABLE BUILDING WITH BRICK IN AN URBAN CONTEXT

Green building

The housing project 'Heath Lodge' in Ealing, London is an example of how site limitations can create opportunities. Labelled as a complex and difficult site to develop, Autor Architecture created a concept that respects the environment as well as the wishes of residents and neighbors. The site consists of an exposed front corner element and a concealed rear element. Ealing council released it for redevelopment in 2005. Attempts by others to develop the site failed for viability reasons.

SUSTAINABLE BUILDING WITH BRICK IN AN URBAN CONTEXT

Green building

The housing project 'Heath Lodge' in Ealing, London is an example of how site limitations can create opportunities. Labelled as a complex and difficult site to develop, Autor Architecture created a concept that respects the environment as well as the wishes of residents and neighbors. The site consists of an exposed front corner element and a concealed rear element. Ealing council released it for redevelopment in 2005. Attempts by others to develop the site failed for viability reasons.

To the front the site’s constraints reduce the buildable area to about 35%. This includes five root protection areas that penetrate into the site. Additionally, the neighbouring properties are two-storey and do not provide useful building lines or height references. The rear part spans the rear gardens of 35 neighbouring properties. Key constraints of the neighbours were: overlooking, overshadowing, dominating impact, noise, privacy, amenity space and site access. The architects successfully worked with ten consultant teams to address and resolve each of the 48 reasons for refusal which were raised by the council.

Finding a solution
Apart from these issues, the site is very valuable for housing as it has a good access to public transport, schools, community facilities, local shops and services. Therefore a solution was needed to establish living space. The scheme has been designed to ensure no adverse impact on the residential amenity of neighbouring properties in terms of sunlight, daylight, outlook or privacy. It has no dominating relationship to any neighbouring buildings or gardens. The building volume was carefully examined for its relationship to the existing neighborhood and with regard to building height and façade to façade distances. A daylight and sunlight assessment was undertaken to examine the scheme for overshadowing of neighboring properties. The façades of the mews allow maximized outlook for residents, but minimize the overlooking of existing neighboring gardens. This is achieved by the installation of screens over some windows.

Overall the scheme establishes a harmonious link between local heritage, urban design, constraints & opportunities, site layout and floor plan functionality. 29 residential dwellings including 18 affordable homes have been constructed, with ancillary parking, landscaping and amenity space.

Heath Lodge is one of our most successful examples for an integrative, density-driven design approach that due to its inherent links to its context and community convincingly addressed the 48 previous reasons of refusal.

Brick as the right choice
The choice of the type of brick played a key role into the design. The light color and texture give the building a warm and earthy character. Furthermore, the material allows the creation of a link between the new development and the neighboring sites and integrates harmoniously into the urban surroundings. The neighbourhood’s general architectural style is late Edwardian and Victorian housing, as is generally found in suburban areas of London. All materials were chosen with consideration to reduced environmental impact.

Sustainable building
Besides the use of sustainable materials, improved insulation values and renewable sources account for about 20% of the used energy on site. This includes solar panels, under floor heating, heat recovery units and rain water harvesting. Water use has been reduced by the use of dual flush toilets, low flow fittings and efficient appliances. Water butts for rainwater are to be installed in the private amenity space for irrigation.

The project is a huge success; Heath Lodge is shortlisted for four awards this year in the UK, including “Housing Development of the Year”.
