Extensions

Single and double-storey home extensions that add space and blend with your existing property.

An extension can give you the extra kitchen, living or bedroom space you need without the cost and disruption of moving home.

Ecoficiency builds rear, side and wrap-around extensions, working from your drawings and paying close attention to how the new space connects with the existing house.

Types of extension

  • Single-storey rear extensions, including kitchen-diner extensions
  • Side return and wrap-around extensions
  • Two-storey extensions, subject to approvals
  • Garage conversions and link extensions
  • Internal alterations to connect the new and existing space

Things to consider

Many single-storey extensions fall under permitted development rights, while others need full planning permission. All extensions require building regulations compliance. Your designer or local authority can confirm what applies to your property.

Integration matters as much as the new structure: floor levels, rooflines, drainage, heating and electrics all need to connect neatly with the existing home. We plan these details before work starts.

Living at home during an extension is often possible with sensible phasing. We will talk through access, dust control and when temporary disruption is likely.

How extension projects typically run

  1. Site visit. We see the property and discuss what you want to achieve.
  2. Drawings and approvals. Confirm your drawings and the approvals needed.
  3. Written quote. A clear scope covering structure, finishes and connections.
  4. Build. Groundworks, structure, roof and weatherproofing.
  5. Connect and finish. Open up to the existing house, then complete internal finishes.

Materials & finishes

  • Brick, block or render to match or complement the existing house
  • Flat or pitched roofs, roof lights and lanterns
  • Bi-fold, sliding or French doors to your specification

FAQs

Extensions Questions

Common questions about extensions. If your question isn’t answered here, contact us.

Do I need planning permission for an extension?

It depends on the size, position and your property’s history. Some extensions qualify as permitted development. Check with your local planning authority or designer before work begins.

Can you match the existing brickwork?

We aim to source materials that match or deliberately complement your home. Exact matches can depend on the age of the property and material availability.
