At a house on Wynchgate in Enfield, the design brings together three ways of making more useful space: extending at the rear, converting the garage and creating a new bedroom suite within an enlarged roof. Considering these changes together allows the shared living areas, quieter rooms and upstairs accommodation to work as parts of one home.
Enfield Council granted householder planning permission on 10 June 2026, under application 26/01393/HOU. The scheme granted permission includes a single-storey rear extension, first-floor side extension, garage conversion, rear dormer, front rooflights and changes to the front and side windows. The drawings shown here illustrate that planning scheme.
More usable space at the top of the house
The side of the roof changes from a hip to a gable, with a dormer at the rear. Together, these alterations make more of the roof space usable and allow a bedroom, dressing area and en suite to sit around a new staircase from the first-floor landing.
The loft plan marks the changing head heights and retains access to low-level storage under the remaining roof slope. This is a practical part of loft conversion design: the space under the eaves can provide storage while the taller areas accommodate movement and everyday use. Four rooflights bring light through the front slope, supplementing the rear dormer windows.
Adding a bedroom with its own bathroom creates scope for greater privacy within the home. The design also considers how it is reached, with the new stair integrated into the existing circulation rather than relying on access through another bedroom.
Connecting shared living space with flexible separate rooms
The rear extension replaces the existing rear addition and creates a broader kitchen and dining area overlooking the garden. In the approved arrangement, rooflights bring daylight into this space from above and sliding doors open towards the patio. A seating area sits within the existing house behind the extension, keeping cooking, meals and relaxation connected.
This approach to house extension design considers the rooms behind the new building as carefully as the extra floor area. The front living room remains separate, providing a quieter alternative to the shared space at the rear.
The garage conversion adds another usable room within the existing footprint. The planning layout shows it as a study, with a new front bay replacing the garage entrance and relating to the existing bay beside it. The combined scheme therefore provides both more communal space and greater choice about where to work or spend time separately.
Working through the roof form and neighbouring relationships
A key planning consideration was how the enlarged side and roof would relate to the neighbouring houses and the character of Wynchgate. Our planning case examined comparable local roof and side extensions alongside the particular setting of this property. This illustrates the value of project-specific planning advice: nearby examples can inform the discussion, while each proposal still needs to be assessed in its own context.
The approved elevations use matching render and roof tiles, with render and timber detailing to the front bays. The permission also includes specific privacy safeguards for the first-floor side glazing and prevents the extension roofs being used as recreational terraces. These requirements form part of the design’s relationship with adjoining homes.
Wynchgate shows how a roof extension, garage conversion and rear addition can be planned together to offer more flexibility throughout a house. If you are considering a similar combination, book a call to discuss which changes would make the greatest difference to your home.
