A shallow recess beneath an existing first-floor overhang offered a useful opportunity at Fernhill Cottage on Hatchet Lane, Winkfield. Detailed Planning secured permission for an infill extension that would give the kitchen a dedicated dining area beside the garden, together with replacement walls to the overhanging first floor and a small rear porch.
Bracknell Forest Council approved the scheme on 11 September 2026 under application PA/2026/0687. The design concentrates the changes around an existing part of the cottage, retaining its overall roof form and the separate rooms that give the house much of its character.
Making the space beneath the overhang useful
The first floor already projects beyond the kitchen wall. Enclosing the recess below it brings that sheltered area into the house, creating room for a dining table along the rear of the kitchen. The approved plan retains the existing kitchen and places a larder at one end of the new dining space, keeping food storage close to where it is needed.
This is the kind of opportunity that careful architectural layout design can reveal: a relatively small addition can change where people sit, how they move around a room and how the kitchen relates to outside. Here, the dining area would allow everyday meals to take place beside the garden while keeping the cottage’s separate dining room, reading room and living room.
A garden connection suited to the cottage
Bi-folding doors across the new dining area are designed to open the room towards the garden. Their appearance follows the existing style, helping the new opening sit comfortably within the long rear elevation. The proposal also includes a timber-and-brick porch with a tiled roof over the rear entrance, giving that doorway a more sheltered approach.
Keeping these changes together matters. The doors, porch and infill all affect the same stretch of wall, so their proportions and materials need to work as a group. The rear elevation shows how they relate to the windows above and the cottage’s established roofline.
A limited addition in a Green Belt setting
The cottage lies within the Metropolitan Green Belt. The planning case focused on the contained nature of the infill beneath an existing projection and the reconstruction of the first-floor walls on their existing footprint. The roof above remains in place, with no proposed increase in its height or outward projection.
The council’s permission ties the work to the submitted drawings and the specified external materials. This illustrates why planning advice linked to the design is useful when considering changes to a sensitive site: the extent of the work and its relationship with the existing building need to be clearly explained.
Working with the house that is already there
The approved scheme brings together a more useful kitchen edge, a sheltered entrance and replacement walls to the building above. Structural details would need to coordinate the replacement first-floor construction with the opening below. Exploring those relationships is part of our design and technical process.
