More space.
Designed around real life.
Architectural and structural design for rear, side, wraparound and two-storey extensions—coordinated from the first idea to technical information.
An extension should improve the whole house—not just add floor area.
Good extension design considers how the existing rooms, garden, daylight and circulation work together. We shape the proposal around the way you want to use the home and the approvals needed to deliver it.
Architectural and structural requirements can be coordinated within one route, reducing gaps between the design intent and the construction information.
Extension design for different homes and ambitions
The right solution depends on the property, site and outcome—not a one-size-fits-all layout.
Rear Extensions
Open-plan living, kitchen and family spaces connected more effectively to the garden.
Side Extensions
Use side-return or side-space opportunities to improve width, storage and circulation.
Wraparound Extensions
Combine rear and side additions into one coordinated transformation.
Two-Storey Extensions
Create additional space across two levels while resolving structure and massing.
Planning Drawings
Existing and proposed information prepared for the relevant planning route.
Building Regulations
Technical drawings coordinated with structural and regulatory requirements.

Straight answers about scope, information and project delivery.
Do all extensions need planning permission?
No. Some work may fall within permitted development rights, while other projects require planning permission. The property and proposal must be reviewed.
Can you provide structural calculations too?
Yes. Architectural and structural design can be coordinated where both services are included in the agreed scope.
What should I send first?
Send the address, photographs, a brief description and any existing plans or sketches.
Can you help with Building Regulations drawings?
Yes. Technical drawings can be prepared for the agreed regulatory scope.
Do you design extensions nationwide?
Yes. Suitable extension projects are supported across the United Kingdom.
