Single storey
A ground-floor room, usually a kitchen and dining space, with doors or a roof light bringing the garden in.
An extension should feel like part of the original house, not a box stuck on the back. We start with how you cook, sit, and get into the garden, then draw the smallest plan that does that well.
Double storey
Ground and first floor together. Useful when you need both a larger living space and another bedroom.
Side return
The narrow alley beside a terrace or semi, brought into the kitchen. A small footprint that changes how the ground floor works.
Wrap-around
Side return and rear extension as one L-shaped room. More glass, more structure, and a layout that needs careful planning.
What is included
- Layout options before drawings are frozen
- Planning or permitted development, as required
- Foundations, structure, and roof
- Glazing, kitchen, and floor finishes to the agreed spec
- Drainage and making good where we join the old house

Questions
Some extensions sit within permitted development. Others need a full application. We check the house, the street, and any earlier approvals, then tell you which route applies before you commit to drawings.
