About Our Sheffield Service

## Local builders, working in Sheffield every week

Sheffield is one of our most active areas. We're on the road in S-postcodes most weeks of the year, with current projects spread between Nether Edge, Crookes, Hillsborough, Dore, Totley and Bradway. The city's mix of Victorian terraces, inter-war semis and modern detached homes means no two enquiries are quite the same — which is exactly how we like it.

What Sheffield homeowners share, regardless of postcode, is a need for builders who actually understand the city: the steep gardens, the side-return constraints on terraced rows, the conservation areas in Nether Edge and Sharrow, and the very specific Sheffield City Council building control process. That's where 20 years of working in S-postcodes counts.

Every job is delivered by our own tradesmen end-to-end. No subcontracting your kitchen-diner extension to whoever has a free week.

Why Choose Us in Sheffield

## What makes us the right builders for Sheffield

### Side-return specialists

Side returns are the highest-value, lowest-disruption extension you can build on a Sheffield terrace. We've completed dozens — including the structural steel, party wall, drainage diversion and rooflight detailing — and know exactly what Sheffield City Council building control will and won't approve.

### Conservation-area aware

Properties in Nether Edge, Sharrow Vale and parts of Crookes sit inside conservation areas. We work with Sheffield's planning officers regularly and know which materials, openings and rooflights will pass.

### Mansard & dormer experience

Sheffield's terraces and semis are perfect mansard candidates. We've delivered full mansard lofts with bedrooms, en-suites and Juliet balconies across S6, S7, S10 and S11.

### Quote in 48 hours

After a free site visit anywhere in Sheffield, you'll have an itemised written quote in your inbox within two working days. No vague 'around £60k' chats.

Local Knowledge

## Sheffield property types we work with

### Victorian terraces (Nether Edge, Crookes, Walkley)

Side-return extensions and rear kitchen-diners are the killer combo. Typical brief: knock through to one big open-plan space with bifolds onto the back garden. £45–80k delivered.

### Inter-war semis (Hillsborough, Ecclesall, Fulwood)

Cavity walls, decent footings and side access. Two-storey side extensions and hip-to-gable lofts are common. Often combined with a rewire and a kitchen replacement.

### Detached family homes (Dore, Totley, Bradway, S17)

Larger budgets, larger footprints. Wrap-around extensions, garden rooms, garage conversions and master-suite-over-garage projects in the £80–180k range.

### Stone-built character properties

Sheffield's stone vernacular needs matching materials. We source reclaimed stone where required and detail extensions to read as part of the original.

Building Control & Planning

## Working with Sheffield's council

Building work in Sheffield is submitted to Sheffield City Council Building Control on Howden House. Conservation-area applications take longer (8–10 weeks rather than 8) so we factor that into your programme upfront. Where listed-building consent is needed (uncommon, but possible in older Nether Edge stock) we'll flag it at the first site visit and recommend a heritage consultant.
