Types of Extensions We Build

Single-Storey Extensions

The most common way to add a kitchen-diner, family room or extra living space without the cost of building up.

Groundworks, foundations and structural work
Bi-fold or patio doors and roof lanterns for light
Full integration with your existing roofline and brickwork
Insulation, plastering and first-fix electrics
Complete finishing – flooring, decoration, final snagging

Multi-Storey Extensions

A larger project that adds space on more than one floor — often an extra bedroom or en-suite above a ground-floor extension

Structural engineering and building control sign-off
Steelwork and load-bearing alterations where needed
Matching external finishes to your existing property
Staircases and internal reconfiguration if required
Coordination of all trades under one point of contact

Extending in Honiton and Sidmouth

Honiton’s town centre and surrounding conservation areas include a number of listed and period properties, where extension design needs to respect the existing character and may need planning permission rather than falling under permitted development.

Sidmouth’s mix of Georgian townhouses, Victorian terraces and more recent housing brings a similar range of considerations — we handle the planning and building regulations conversations as part of the job, not as an extra.

Frequently asked questions

Do I need planning permission for a home extension in Honiton or Sidmouth?

Many single-storey extensions fall under permitted development and don’t need full planning permission, but this depends on the size, your property type, and whether it’s in a conservation area. We check this for you as part of the initial visit and handle the application if one’s needed.

How long does a home extension take?

A single-storey extension typically takes 10–14 weeks from groundworks to completion; a multi-storey extension takes longer. We give you a realistic schedule at quote stage, not just an estimate.

Do you work from my architect's drawings?

Yes — we’re happy to cost and build from plans you already have. If you don’t have an architect yet, we can point you toward the right next step.

How much does a home extension cost in Devon?

Costs vary a great deal by size, specification and site access. We always provide a clear, itemised quote after seeing the property rather than a generic per-square-metre figure.
