A garden pergola provides inspiration for a new East London extension

Garden Pergola Extension | Architects for Newham | East Ham, East London

forresterarchitects has designed a new rear garden pergola extension that takes full advantage of the orientation of the property located in East Ham, East London, in the borough of Newham. The extension has been carefully planned to allow the garden to receive sunlight throughout the day, from early morning to late evening, as the sun moves across the sky to the west. The extension has been designed to improve the visual connection between the house, the garden, and the sky beyond.

The pergola extension is characterized by a series of layers that frame views and create a strong sense of connection between the interior and the garden. The design takes into consideration the orientation of the property and the movement of the sun throughout the day. An exposed roof structure extends into the garden to form a garden pergola that provides a passive solar shading device to the interior. The pergola will protect the interior from direct sunlight while allowing for natural light to enter the space. The design will also help to regulate the temperature of the interior space, reducing the need for artificial heating and cooling.

The garden pergola extension will provide a beautiful and functional addition to the property. The pergola will create a shaded outdoor space that can be used for dining, relaxation, and entertaining. The extension will also enhance the visual appeal of the property, creating a seamless connection between the interior and the garden. The design will provide a contemporary and stylish solution that is sympathetic to the existing property while providing a new and exciting space for the owners to enjoy.


A new one bed flat extension in the garden vernacular

One Bed Flat Extension | Architects for Oxford | Temple Cowley, Oxford

forresterarchitects have developed a unique one bed flat extension for a corner plot in Temple Cowley, Oxford. The project involved creating a one-bedroom flat extension that considered the site constraints imposed by the irregular property demise. The feasibility studies revealed that a conventional rear extension would obstruct access to the rear garden or potentially conflict with the neighboring property.

Instead, forresterarchitects designed a new addition that allows for the reconfiguration of the existing floor plan. The dining and lounge areas are located between the bedroom and extension to provide a bright and airy living environment. Additionally, the new extension provides a second bedroom and a dedicated studio/library for the academics. The design solution is considered and well-executed, providing a considered response to the unique challenges of the site. By creating a one-bedroom flat extension that works with the property’s irregularities, forresterarchitects were able to maximize the space available and provide a comfortable and functional living environment. The addition of a second bedroom and dedicated studio/library adds value to the property and meets the client’s specific needs.

Avoid the conventional and there is no Downside!

House Refurbishment  | Architects for Camden | Belsize Park, North West London

The fine semi-detached Villa’s of Belsize Park, North West London is in a wonderful setting. Separated by only the small side passages between the houses. Only the neighbouring houses form a boundary to the gardens, which are long, wide and mature in foliage. This is the setting for our latest full house refurbishment. The client wanted the house to feel better connected to the garden. 
An accordion arrangement is explored as a concept for the extension. A series of angled facets have been used to establish a notional hierarchy to the kitchen. Expressed as solid and void walls the facets provide a level of transparency and privacy between the house and gardenThe staggered configuration of the extension creates framed views of the garden and a unique architectural solution. See four new build houses realised to an inner city brownfield site.
The innovative design avoids the usual full width house extensionThe shift in geometry allows the extension to reveal a series of layered materials to reach out and touch the garden. All contained beneath the asymmetrical roof form. The roof is formed in timber and painted with a special Swedish preservative paint treatment. It produces a beautiful matt red finish. The roof projects beyond the building edge to provide a simple solar shading device to south facing aspect of the extension.

Not the only way to do a dormer conversion…

Our ‘butterfly’ roof is featured in Dezeen.

Save The London Roof | Architects for Hackney | Stoke Newington, Hackney

The London butterfly roof is fast disappearing! As people don’t move and improve their homes, converting the roof space no longer protects the distinct parapet rooflineKeen to avoid the mundane lean-to extension, the new rear extension is a modern interpretation of the traditional London Roof form.
The roof provides an enlivened architectural language to the rear gardens of this mid-terraced house in North London. The ‘butterfly’ roof is expressed as exposed timber rafters. It provides a dynamic architectural feature and natural warmth to the living room. The original ceiling height was too low for a living room so it was necessary to excavate to create a more generous room volume. The new living floor level has been reduced to provide a ceiling height more in keeping with the rest of the house.
A new wood-burning stove provides a focal point to the living room. A new library wall which hangs from the timber rafters occupies one side of the living room. In the evening the lighting is subtle and located with indirect spotlights and avoids the need for pendant lights hanging in the room.
As part of the refurbishment works the entire ground floor has been reconfigured. The kitchen has moved from the back of the house and has been relocated between the new living room and the dining roomThe kitchen avoids high-level cupboards with two long counters providing an extensive work surfaces area to each side. The dining room has moved to the bay fronted room overlooking the street. The dining room retains many of the traditional decorative features expected of a Victorian terrace house. The colour scheme is bold and is complimented by the addition of a modern 1950’s furniture and light fittings. The dining room is now orientated for breakfast with the sun rising from the East. To the West, a large hexagonal glass window frames views of the small garden for the setting sun in the evening.
