Extension Types We Specialise In
making planning permission simple, predictable, and affordable for every homeowner and developer in the UK — without the delays, jargon, or inflated fees that hold projects back.
Rear Extensions
Perfect for expanding kitchens, dining rooms and open‑plan living spaces. We design rear extensions that maximise light, improve flow and meet all local planning requirements.
Common uses:
– Kitchen/diner extensions
– Open‑plan layouts
– Single or double‑depth rear builds
Side Extensions
Ideal for unlocking unused side space and improving circulation. We ensure compliance with separation distances, daylight/sunlight standards and character policies.
Common uses:
– Side returns
– Utility rooms
– Home offices
Front Extensions
Front extensions require careful design due to their visibility from the street. We prepare drawings that respect building lines, roof forms and local character guidance.
Common uses:
– Enlarged porches
– Entrance halls
– Improving façade symmetry
Wrap‑Around Extensions
A combination of rear + side extensions to create a large, open‑plan ground floor. We manage all considerations including massing, overshadowing and neighbour impact.
Common uses:
– Large kitchen/living/dining spaces
– Structural reconfiguration
– Maximising ground‑floor footprint
Double / Two‑Storey Extensions
Significant additional space with careful attention to scale, proportion and privacy. We ensure compliance with height, overlooking and roof alignment policies.
Common uses:
– Additional bedrooms
– Ensuite bathrooms
– Increasing long‑term property value
Infill Extensions
Designed to make use of narrow gaps, side passages or unused pockets of space. We create infill solutions that feel natural, balanced and light‑filled.
Common uses:
– Side passage infills
– Courtyard enclosures
– Linking existing structures
