A modest front extension can improve several parts of a home at once. At 43 Elmhurst Road in Mottingham, the proposal brings together a new entrance porch, a more useful guest room and a ground-floor shower room, while reshaping the roof over the existing side extension.
Bromley Council granted householder planning permission on 18 August 2026 under application 26/02402/HPA. The design focuses the additional space at the front of the house, retaining the rear kitchen, dining room and garden arrangement.
Turning the side room into flexible accommodation
The existing office is extended towards the front and shown as a guest room in the proposed layout. Its position beside the hallway gives it a clear route from the entrance, separate from the main living and dining rooms. This creates another place to accommodate visitors without changing the first-floor bedrooms.
Alongside it, the existing WC is enlarged to provide a shower room. Doors from both the guest room and the utility area allow it to serve visitors as well as everyday ground-floor use. The layout brings sleeping and washing facilities together while keeping the shower accessible from the rest of the house.
A frosted rooflight introduces daylight from above. That is a useful response to a room placed within the narrow side accommodation, where privacy matters and wall space is needed for the fittings. The benefit comes from considering the room, doors and roof together, as part of our architectural design and layout service.
A clearer entrance to the house
The new porch sits in front of the existing hallway. Retaining the inner doors creates a small enclosed space between the new front door and the main circulation area, with side glazing beside the outer entrance. This gives the arrival sequence a distinct threshold before entering the house.
The porch and guest-room extension are designed as one composition across this part of the frontage. The new room’s window follows the appearance of the existing windows, and the render is specified to match the house. A related front porch project in East Herts offers another example of an entrance addition considered alongside internal alterations.
Responding to the neighbouring frontage
The roof combines a tiled pitch at the front with a flat section over the side accommodation. This gives the addition a pitched edge facing the street while accommodating the shower-room rooflight behind it.
The planning statement compares the proposal with the existing projection at neighbouring No. 45: the new addition is designed to be shallower and lower. That comparison helps explain its scale within an already staggered frontage. Preparing a clear account of the design and its surroundings is part of our householder planning application service.
From the approved design to technical details
The permission requires the work to follow the approved plans and the stated external materials, with development beginning within three years of the decision. The new roof junctions, shower-room drainage and alterations to the side wall then need to be resolved through the technical design.
Our building regulations drawings service develops that construction information. If you are looking to improve an entrance or create more flexible ground-floor accommodation in Mottingham or Bromley, book a call to explore the possibilities for your home.
