Double-storey extensions in Old Trafford

We take on double-storey extensions in Old Trafford as a complete project: survey, drawings, planning or permitted development checks, building control and the construction itself.

Covering Old Trafford

Old Trafford is about 3 miles south-west of Manchester. We also cover Stretford (1 miles to the south-west), Salford and Eccles.

Homes in the North West

Across the North West, Victorian terraces, inter-war semis and modern estates all feature, and brick or stone matching is chosen to suit each street.

What goes into a double-storey extension?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

  • Householder planning application
  • Foundations, steelwork, brick and block walls, roof
  • Joining the new first floor to the existing landing

Do you need permission for a double-storey extension in Old Trafford?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

Two-storey rear extensions can sometimes be permitted development in England (no more than 3 m deep, at least 7 m from the rear boundary, roof pitch to match), but most two-storey and all two-storey side extensions need householder planning permission.

What can change the price or programme?

  • Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
  • The first-floor link can mean moving a bathroom or reshaping the landing.

What are the steps?

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

What people ask before starting

Does a two-storey extension need planning permission?

Usually yes. In England some two-storey rear extensions are permitted development, but side extensions over one storey always need planning permission.

Is a two-storey extension better value than a single-storey one?

Per square metre, usually yes, because the foundations and roof serve two floors of space.

Who deals with the council for a project in Old Trafford?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
