Project Overview
Aluminium bifold doors in Brixton were specified as part of a two-storey extension to this large end-terrace family home, featured in episode four of Channel 4’s George Clarke’s Old House, New Home. The renovation was designed to retain the property’s period character while creating a larger kitchen and dining space suited to contemporary family life.
Sieger Systems supplied the rear bifold opening, a large rooflight and a slim aluminium casement window. Together, these elements increase daylight, connect the new kitchen to the garden and help integrate the extension with the existing internal spaces.
Project Challenges
Aluminium bifold doors in Brixton for a period family home
The project needed to modernise a house with established period features, including historic chimney breasts and fireplaces, without removing the character built up through its earlier use. The new extension therefore had to provide more space and daylight while remaining clearly connected to the existing home.
Extending the rear also changed the role of the former kitchen, leaving it between the original rooms and the new addition. The design needed to give this area a renewed purpose and ensure that daylight from the extension travelled beyond the new kitchen into the older part of the plan.
At the garden elevation, the homeowners required a wide opening for access and ventilation. Overhead glazing and a separate aluminium window were also needed so that daylight was not dependent on the rear doors alone.
Project Solutions
Bifold garden opening with rooflight-led daylight
Sieger 120 Bi-Fold Doors were installed across the rear elevation of the new kitchen and dining space. The folding arrangement allows the glazed opening to be substantially cleared, creating direct access to the garden and supporting natural ventilation during warmer weather. When closed, the glazed leaves continue to provide views and daylight across the rear of the house.
A large rooflight was positioned above the dining area at the junction between the new and existing parts of the building. This introduces top light into the centre of the plan and helps draw daylight beyond the extension into the earlier rooms. Positioning the dining table below the rooflight also gives the overhead glazing a defined role within the internal layout.
A slim framed aluminium casement window provides an additional source of daylight and controlled ventilation. Together, the bifold doors, rooflight and window distribute glazing across the rear extension rather than concentrating every requirement within one opening.
Project Highlight
The rooflight was positioned to bridge the existing house and new extension, bringing daylight into both parts of the plan. Combined with the rear bifold opening, it creates a dining space that remains visually connected to the garden while directing light deeper into the original building.
End Result
Performance considerations
The aluminium bifold doors in Brixton provide the main route for garden access and purge ventilation within the extended ground floor. Their folding operation allows the homeowners to adjust the opening according to the weather, from partial ventilation to a substantially open rear elevation.
The rooflight introduces daylight from above, reducing reliance on the garden-facing doors and improving light levels around the transition between old and new construction. The aluminium casement window provides a separate opening element for controlled airflow and additional daylight.
This distribution of opening and fixed glazing supports the practical use of the kitchen and dining space throughout the year. It also allows the extension to achieve a more open character without altering the historic features retained elsewhere in the house.
Sieger’s conclusion
Chaucer Road demonstrates how aluminium bifold doors in Brixton can be coordinated with roof glazing and casement windows to modernise a period family home without removing its established character. The bifold opening provides garden access, while the rooflight and window bring daylight into different parts of the extended plan.
This approach is suited to architects, designers and homeowners working on period house extensions where contemporary circulation, natural light and garden access must be introduced alongside retained architectural features.
