House Extension Whetstone

Local Authority: London Borough of Barnet

Brief: Single storey rear extension to create modern kitchen and living

Detailed Planning are proud to present this modern rear extension. Our client approached us with the brief to provide a new large, open, bright and modern kitchen living area. Their current conservatory was impractical as it was hot in the summer, cold in the winter.

The proposal was to demolish the conservatory and construct a new large extension. Although the depth of the extension is more than Barnet planning policies stipulate, by incorporating a step in, loss of light to the neighbour is reduced and the proposal was therefore approved.

Our professional design team incorporated a complex steel design to provide reduced masonry to allow for wide views of the garden. The steel has been exposed externally which ads a modern contrast compared to the original.

Underfloor heating has been used throughout the extension area with compatible floor insulation, this provides a comfortable room without the clutter and loss of wall space that radiators create.

The kitchen is a beautiful design provided by a local designer. Materials used throughout encourage the reflection of light into the central areas of the home.

By incorporating a large sky lantern, not only is there an illusion of added height, the central areas are flooded with light. Using a sky lantern is a wow factor to this extension however, it also is practical, as these reduce rain noise and cleaning requirements due to the angles of the glazing.

Due to the large amounts of glazing, a SAP calculation was required to justify the CO2 emissions, this suggests methods, such as a new eco boiler so the works complies to current Building Regulations Part L.

Detailed Planning provided a recommended local builder,  the builder completed this on time and budget. Our client is now enjoying their extension, for years to come!
