Coverage
Stevenage is 25 minutes from our Buntingford yard down the A10 and A602 — comfortable same-day reach for site visits and one of our busiest local geographies. We cover SG1 and SG2 postcodes across Old Town, Bedwell, Chells, Pin Green, Symonds Green and the new-build ring at Great Ashby.
Response time
Site visits in Stevenage are typically booked one to two weeks out. Because the drive is manageable, we run daily site attendance on Stevenage projects rather than block trips, which suits homeowners who want to be able to talk through decisions on the day they come up.
Property types
Stevenage's housing is dominated by post-war new-town development, 1950s to 1970s family homes with generous plots and loft space, plus more recent 1990s–2020s estate development around the north and west of the town. Older stock in Stevenage Old Town includes Georgian and Victorian High Street property and pre-war semis in the surrounding streets.
Most-booked here
The most-booked Stevenage projects are single-storey rear extensions (opening the kitchen into the garden), loft conversions (adding a fourth or fifth bedroom to a three-bed semi), full kitchen and bathroom refits, and bespoke fitted-wardrobe joinery in bedrooms that came without built-in storage.

Local building context
What actually matters when you build or renovate in Stevenage.
Property age, ground conditions, planning context and local building stock all shape how a project should be quoted and run. Here's what we account for.
Three-bed semis with wasted loft space
The single most-common Stevenage renovation opportunity is the standard three-bed semi with generous but unused loft space. The value uplift from converting it properly — proper staircase, en-suite, eaves storage — is enormous. The value uplift from converting it badly is negative.
New-build joinery that hasn't lasted
A significant proportion of Stevenage's estate housing was finished with the cheapest possible internal joinery — thin doors, hollow architrave, warping skirting, wardrobes with no wall support. Whole-house internal joinery upgrades are one of our regular Stevenage jobs.
Rear extensions and permitted development
Most Stevenage rear extensions fall under permitted development — but not all, and the rules on how far you can extend past the original rear wall depend on whether the property is detached or semi-detached, and on any earlier extension the previous owner may have added. We check this before drawings, not after.
Kitchen-diner knock-throughs and steels
Post-war Stevenage housing typically has a load-bearing wall between kitchen and dining room. Removing it — the single most-common renovation ambition here — needs proper structural engineer input, correctly-sized steels, and joinery detail on the boxed-in beam that decides whether the finished room looks intentional or looks like a compromise.

Stevenage FAQ
Straight answers on working in Stevenage.
Cost, timing, coverage, guarantees — the questions we're asked most by Stevenage homeowners.
- Do you cover the whole of Stevenage?
- Yes — all of SG1 and SG2. Old Town, Bedwell, Chells, Pin Green, Symonds Green, Great Ashby and everywhere in between.
- How much does a single-storey rear extension cost in Stevenage?
- As a 2026 guide, a good-quality build shell typically runs £2,600–£3,600 per m² depending on glazing, roof type and internal spec. Kitchen, decoration and floor finishes are itemised separately. We provide fixed written quotations after a site visit.
- How much does a loft conversion cost in Stevenage?
- Typically £55–£85k for a rear dormer and £75–£110k for a hip-to-gable with rear dormer, depending on en-suite spec and finish. Fixed itemised written quotations after a site visit.
- Do you handle planning and building control in Stevenage?
- Yes — we coordinate with Stevenage Borough Council's planning and building control teams, book and attend inspections at every notifiable stage, and hand over final certificates at completion.
- How long does a Stevenage extension or loft take?
- Single-storey rear extensions: 12–20 weeks on site. Loft conversions: 8–14 weeks. Programme is written into the contract before we start.
- Can we stay in the house during the build?
