Extensions

House extensions in Stratford-upon-Avon, Solihull and across the West Midlands.

We build house extensions across Stratford-upon-Avon, Solihull and the West Midlands. Our team manages the groundworks, structure, trades and finish from start to handover.

Types of extension

Pick the footprint that suits your home.

On the first visit, we'll explain which option makes best use of your home and budget.

Single-storey rear

Opens up the back of the house for a bigger kitchen-diner, a garden room, or a knocked-through living space.

Build time
12-14 weeks
Investment
On enquiry

Double-storey rear or side

Adds a bedroom and en-suite above new living space. Usually the best value per square metre, because one set of foundations and one roof cover two floors.

Build time
16-20 weeks

Wraparound / L-shaped

Combines a side-return and a rear extension into one footprint. A big change for Victorian and Edwardian terraces.

All timings are a guide. The real programme depends on the specification and the individual job. We give you a realistic timeline with your quote.

Property extensions to suit your needs

An extension can add living space, improve a poor layout or create a larger kitchen. We start with a site visit to understand what you need, check what the property allows and discuss a realistic budget.

We construct a range of different home extensions, including:

  • Rear Extensions
  • Side Extensions
  • Single-storey Extensions
  • Two-storey Extensions
  • Kitchen Extensions
  • Wraparound Extensions

Rear, side and wraparound extensions can all add useful space and value. The right option depends on the house, garden and budget.

If you're unsure which route to take, we'll inspect the property and give you a straight recommendation.

Planning & design

The bit most builders try to skip.

We'd rather spend an extra fortnight at drawing stage than find out at first-fix that the steel won't sit on the wall. Our process front-loads the boring decisions so site stays calm.

  1. 01

    Permitted Development check

    We confirm whether your scheme falls under PD or needs a full householder application, and what the realistic outcome is in your council.

  2. 02

    Architect coordination

    We work alongside trusted West Midlands architects (or yours), feeding back buildability and cost as the drawings evolve.

  3. 03

    Structural engineering

    Padstones, beams, raft details and lateral restraint specified in writing before bricks are ordered.

  4. 04

    Building Regulations

    Full plans submission to your local Building Control or an Approved Inspector, inspection schedule agreed upfront.

  5. 05

    Party Wall surveying

    Notices served, surveyors instructed and award in place before any line is dug closer than 3m to a boundary.

  6. 06

    Fixed-price quote

    A line-item proposal with provisional sums clearly flagged so there are no nasty mid-build surprises.

Build timeline

A typical 4-bed rear extension, week by week.

Week 0

Site visit & feasibility

We walk the property with you, sketch the brief, give honest cost ranges and flag planning risks before you spend a penny on drawings.

Week 1-6

Architect & approvals

We coordinate with our architect partners on planning drawings, structural calcs, and Building Control submissions. Party Wall notices served where needed.

Week 7

Mobilisation

Welfare, hoarding, scaffold, skip and material call-offs scheduled. Neighbours informed in writing before the first vibration.

FAQs

Extensions, asked & answered.

Everything we get asked at the first site visit.

Do I need planning permission for an extension?+

Many single-storey extensions fall under permitted development, but it depends on size, position and your property. We'll tell you honestly at the consultation whether you need a full application.

How long does a typical extension take?+

A single-storey rear extension is usually several weeks to a few months depending on size, groundworks and finish. We give a realistic programme with your quote.

Will you handle building regulations?+

Yes, we manage building-control sign-off as part of the project.

Can you match the existing brick and finish?+

Yes. We source materials to match your existing property so the extension reads as part of the original build.
