Reclaiming the Backland, High Street North, East Ham, London
Two storey rear extension 

-

Location : Eastham, UK
Client : Private
Year : 2021-2022
Stage: Planning stage

82–84 High Street North transforms an overlooked backland condition behind East Ham’s vibrant High Street into a connected and landscape-led residential environment. The proposal replaces the existing rear hip roof with a carefully articulated two-storey extension, creating four residential units comprising two three-bedroom homes and two studios.

Rather than forming a single volume, the extension is broken down into smaller elements that respond to the scale and building lines of the surrounding properties. A sequence of courtyards, terraces and planted spaces is woven through the development, bringing daylight and ventilation into the homes while providing separation and privacy.

The existing rear staircase is reimagined as a green arrival sequence, connecting the individual homes through elevated walkways and planted spaces. Timber screening, planting and carefully positioned openings allow generous glazing while controlling overlooking.

A restrained material palette of red ceramic tile, brick, timber, aluminium and planted roofs responds to the surrounding context while establishing a distinct contemporary identity. The project seeks to transform a neglected backland condition into a series of generous, light-filled homes with strong connections to landscape and the outdoors.

Description

Reclaiming the Backland
- Located behind the busy High Street North in East Ham, the existing residential accommodation sits within a dense and largely overlooked backland environment. While the High Street has a vibrant character, the rear of the properties is characterised by exposed services, refuse storage, external stairs and poorly defined access, creating a stark contrast between the public frontage and the residential environment behind it. 


- The project seeks to transform this overlooked condition into a series of better-connected and more generous homes.
 

- The proposal replaces the existing rear hip roof with a carefully arranged two-storey extension, creating four residential units: two three-bedroom homes and two studios. Rather than treating the extension as a single volume, the building is broken down into a series of smaller elements, responding to the different building lines and scale of the neighbouring properties. 
 

- At the centre of the proposal is a sequence of courtyards, terraces and planted spaces. These spaces bring daylight and ventilation into the homes while creating separation between the new accommodation and its neighbours. The courtyards also provide opportunities for planting and help control views between properties. 
 

- The project treats the access route as more than simply a circulation space. The existing rear staircase is transformed into a more legible and welcoming arrival sequence, with an elevated green corridor providing visual guidance and connecting the individual homes. Landscape is introduced progressively through the development, from the lower-level gardens to planted terraces and sedum roofs. 
 

- Privacy is addressed through depth, planting and layers of timber screening, allowing generous areas of glazing without creating direct overlooking between neighbouring homes. The building lines respond to the existing and approved extensions around the site, helping to establish a coherent relationship with the dense surrounding backland. 
 

- The material palette combines red ceramic tile, timber, brick, aluminium and planted roofs. The colours and tones relate to the surrounding buildings while allowing the new architecture to have its own identity. Green roofs and planting soften the hard, enclosed character of the existing backland and introduce a stronger relationship between architecture and landscape. 
 

- The project is therefore less about simply adding floor area and more about changing the quality of an overlooked piece of the city. By introducing light, landscape, privacy and a clearer sequence of spaces, the proposal turns a neglected backland condition into a collection of homes with their own gardens, terraces, courtyards and connections to the outside.

Reclaiming the Backland
 

- 82–84 High Street North transforms an overlooked backland condition behind East Ham's vibrant High Street into a series of light-filled and landscaped homes.
 

- The proposal replaces the existing rear roof with a carefully articulated two-storey extension, creating two three-bedroom homes and two studios. Courtyards, terraces and planted spaces are woven through the development to bring daylight, ventilation and nature into the homes while maintaining privacy from neighbouring properties.
 

- The existing rear access is reimagined as a green arrival sequence, connecting the homes through elevated walkways and planted spaces. A restrained palette of brick, ceramic tile, timber and metal responds to the surrounding context while giving the new architecture its own identity.
 

- The project turns a neglected backland into a connected, generous and liveable residential environment. 
 

- I think “Reclaiming the Backland” is a particularly strong title for this project because it captures the architectural idea rather than simply describing the extension.
