Double-storey extensions in Leicester

Homeowners in Leicester can get double-storey extensions from one company: the design, the paperwork and the building work sit with us rather than with three separate firms.

Covering Leicester

Our coverage around Leicester (LE1, LE19) also includes Oadby, Wigston and Loughborough.

Homes in the East Midlands

The East Midlands combines red-brick terraces in the cities with a lot of post-war and modern estate housing, so rear extensions, garage conversions and loft conversions are all common.

What goes into a double-storey extension?

Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.

  • Measured survey, design and planning drawings
  • Structural engineer’s design and calculations
  • Windows, insulation, plastering, electrics and plumbing

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

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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. Expect around eight weeks for a decision once the application is validated.

What should I think about before starting?

  • Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
  • The new roof is tied into the old one, so roof tiles and ridge details need to match.

How does the project run?

  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. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

What people ask before starting

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.

Will we need to move out?

Most people stay. The noisiest stage is when we break through into the existing first floor, which we plan for a short window.

Can you visit a house in Leicester to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
