Extensions & Renovations — Hereford & West Midlands

Where most projects start

Bread and butter — done properly.

For the next 12 months, this is where most APMBuild clients will start: a kitchen, a bathroom, a full house refurb, an extension. Not full Passive House new-builds — those are still being scoped — but quality residential work, delivered with European materials and the kind of detailing that lasts.

Position this work as "better than the UK refurb average". The differentiators are real: building physics awareness, direct EU material sourcing, single point of contact, 20+ years of European construction experience.

What makes us different

Building physics awareness

PHI-accredited Level 2 Passive House construction training (AZB, 2023). We think about airtightness and thermal bridges by default — not as an afterthought.

Direct European materials supply

Better products, typically 20–30% below UK pricing. From insulation and windows through to tiles, kitchens and bespoke furniture. See full range →

Single point of contact

Paweł Okurowski, from first call to final handover. No call-centre, no project manager you've never met.

Realistic timelines, transparent pricing

Costed proposals up front. Programme dates agreed before work starts. No surprises mid-project.

20+ years across four European countries

Poland, Germany, Spain (Mallorca), UK. The detailing standards expected on the Continent, applied to British residential work.

What We Cover

The full range of residential work.

Whether you're updating one room or rebuilding most of the house, we work across the full scope of UK residential construction. Energy improvement work is woven through everything — because it's our training and our European supply chain doing the heavy lifting.

Kitchens

Full kitchen design and installation, with European cabinetry, worktops and appliances. Supply-only also available.

Bathrooms

Full bathroom refurbishments with European tiles, fittings, taps and sanitaryware. Wet rooms and family bathrooms.

Full house refurbs

Whole-house renovation programmes. Phased works or vacant-property programmes. Single coordinated package.

Single-storey extensions

Rear, side and wrap-around extensions. Permitted-development scope and full planning routes.

Two-storey extensions

Larger extensions delivering significant additional floor area. Coordination with our UK architect partnership for planning and Building Regs drawings.

Loft & garage conversions

Adding usable floor area without changing the building footprint. Dormers, hip-to-gable, integral garage conversions.

Energy improvements

Part L upgrade works, insulation (EWI, IWI, loft), window replacement, door replacement, airtightness improvements.

External works

Decking, balustrades, retaining walls, garden lighting, hard landscaping. As delivered in Herefordshire 2024.

Materials supply only

If you have your own team, we can supply the materials package only. See the materials page →

Where We Work

West Midlands, Wales and the borders.

Build-and-install work is regional. We work in the counties and areas we can comfortably reach from Hereford and oversee personally — without quality dropping because of distance.

FAQ

Extension and renovation questions

What's included when APMBuild delivers a full extension or whole-house renovation.

What's included in a full extension or renovation?

An APMBuild full extension or renovation typically covers design, structural calculations, planning, Building Control submissions, demolition, foundations, structure, fabric (insulation, airtightness, glazing), MVHR, M&E, finishes, kitchens, bathrooms and bespoke joinery — delivered as a single A–Z contract from our Hereford base.

Can you handle planning and Building Control submissions?

Yes. APMBuild manages planning applications, Building Regulations approval, Party Wall notices and PAS 2035 documentation where relevant. This is included by default in our design-build A–Z service across the West Midlands and Wales.

How long does a typical extension take?

A typical single-storey rear extension with APMBuild runs 12–20 weeks on site once planning and Building Control are approved. Two-storey extensions or wraparound projects run 16–28 weeks. Energy-efficient detailing adds little to programme but a great deal to performance.

Do you do energy-efficient extensions?

Yes — every APMBuild extension is built to a high fabric standard by default, with triple glazing, continuous insulation, airtightness detailing and MVHR available as standard upgrades. This pairs an extension with whole-house energy improvement rather than worsening the existing performance.

What's the warranty on extensions?

APMBuild provides a 24-month workmanship warranty on all extensions and renovations, alongside manufacturer warranties on installed products (windows, MVHR, boilers, kitchens). Full handover documentation including airtightness and commissioning data is supplied on completion.
