Designed around the property

A rear extension should improve both the room and the garden relationship.

The right footprint, ceiling height and glazing arrangement can turn a disconnected ground floor into a practical, light-filled family space.

We balance internal planning with external massing, neighbouring impact, structure and approval requirements.

Design process

Four clear steps from brief to delivery

01

Review the home

Collect drawings, photographs, dimensions and the project brief.

02

Shape the space

Develop the plan, roof, glazing and garden connection.

03

Resolve approvals

Coordinate the design with the applicable planning route.

04

Prepare delivery

Issue the agreed drawing and technical package.

Key considerations

The details that shape a reliable proposal

The final design depends on verified property information, local constraints and coordinated technical decisions.

01

Neighbour impact

Projection and height can affect daylight, outlook and planning acceptability.

02

Internal depth

Removing rear walls can reduce daylight unless roof glazing is planned well.

03

Structure

Wide openings require coordinated beam, support and foundation design.

04

External levels

Thresholds, patios, drainage and garden falls need a practical solution.

Common questions

Rear Extension, clearly explained

Straight answers about design, approvals and technical coordination.

How far can a rear extension project?

The allowable projection depends on property type, location, previous extensions and the planning route being used.

Is a flat or pitched roof better?

Both can work. The choice depends on height limits, upper windows, architecture, drainage and the desired interior.

Can large sliding doors be included?

Yes, subject to structural support, thermal performance and practical threshold detailing.

Will drainage affect the design?

It can. Public sewers, private drains and inspection chambers should be identified early.

Can the design include a new kitchen layout?

Yes. Spatial planning can coordinate the extension with kitchen, dining and utility requirements.
