About Our Barnsley Service

## Local builders, working in Barnsley every week

Johnsons Building Services has been building, extending and renovating Barnsley homes for over 20 years. Our yard and office are based on Copeland Road, S70, which means most jobs we visit are within a 15-minute drive — so when you need someone on site for a survey, a delivery or a follow-up snag, we are not coming from the other end of Yorkshire.

Barnsley's housing stock is varied: Victorian and Edwardian terraces in town, 1930s semis through Worsbrough and Ardsley, post-war semis and detached homes in Athersley, Cudworth and Mapplewell, and newer developments out towards Penistone and Silkstone. Each property type has its own quirks — solid-brick external walls in older streets, narrow plots, party-wall considerations, sloping gardens — and we build accordingly. There is no one-size-fits-all extension in Barnsley.

Every job is delivered end-to-end by our own tradesmen: groundworks, structural steels, brickwork, roofing, first and second fix joinery, plumbing, electrics, plastering, tiling and decoration. You deal with one point of contact from first quote to final sign-off.

Why Choose Us in Barnsley

## What makes us the right builders for Barnsley

### We know Barnsley MBC's planning office

Years of submitting building notices, full plans applications and Lawful Development Certificates to Barnsley Metropolitan Borough Council means we know what gets waved through, what triggers questions, and what'll never be approved before you waste money on drawings.

### Local supply chain

Trade accounts with Travis Perkins Barnsley, Howdens Wombwell, Selco and the brick merchants in Wath give us better prices and faster materials turnaround than firms travelling in from Leeds or Sheffield.

### Real Barnsley reviews

Most of our work comes from word-of-mouth recommendations between Barnsley homeowners. We can usually point you at a finished job in your own postcode that you can drive past — or even visit if the owner is happy to show you round.

### On-site within 24 hours

If you live in S70–S75, we can normally get a project manager round to take a look the day after you call. No two-week waits to be scheduled in.

Local Knowledge

## Barnsley property types we work with

### Victorian & Edwardian terraces (S70 town centre)

Solid 9-inch brick walls, lath-and-plaster ceilings, sometimes no foundations to speak of. Rear extensions usually mean underpinning the existing wall, careful structural opening through the back-addition, and replastering throughout to match. We've finished dozens of these — they reward patience and proper detailing.

### 1930s semis (Worsbrough, Ardsley, Kendray)

Cavity walls, decent footings, generous gardens — by far the best Barnsley property type to extend. Two-storey side or rear extensions, knock-throughs and loft conversions are our most-built jobs in these streets. Typical project value £55–110k.

### Post-war and 1960s–70s semis (Athersley, Cudworth, Mapplewell)

Often single-glazed when we arrive, dated kitchens and bathrooms. Most renovations here are full strip-outs: new windows, rewire, replumb, insulation upgrade, kitchen, bathroom and decoration throughout. £40–80k typical.

### Newer detached (Penistone, Silkstone, Dodworth)

Modern footings and cavity construction make extensions straightforward. Common briefs: orangery-style rear extension, garage conversion to home office, master suite over the garage.

Building Control & Planning

## Working with Barnsley's council

Most of what we build in Barnsley is submitted as a Building Notice or Full Plans application to Barnsley MBC Building Control on Westgate. Where the work is permitted development we'll prepare and submit a Lawful Development Certificate so the title is clean for resale. Party Wall Act notices are handled in-house — we draft and serve them on your behalf where the work affects a shared boundary.
