Extension builders in Sheffield
Plumbery is a London company. We travel to Sheffield, about 145 miles away, for complete projects rather than small repairs, and keep one project lead as your contact throughout.
Sheffield's steep streets mean many extensions need retaining walls, split levels or steps down to the garden. We look at levels and drainage on the first visit, before any design is fixed.
Cost and time
Budget and timescale
A single-storey rear extension typically takes around 10 to 16 weeks on site once approvals are in place. Use the house extension cost calculator for a budget with VAT, or read how we run extensions on our London house extension page.
Local know-how
Before you start in Sheffield
Many single-storey rear extensions in England can be built under permitted development: up to 3 metres deep on a semi or terrace and 4 metres on a detached house, or up to 6 and 8 metres through prior approval. Flats, maisonettes and conservation areas are more restricted, and planning applications go to Sheffield City Council.
What we do
Popular projects in Sheffield
Orangery-style room

Side-return extension
Filling the side passage of a terrace or semi to widen a narrow kitchen.
Glazed rear extension

Our clients
Extensions across Ranmoor, Fulwood, Dore, Totley, Ecclesall and Nether Edge
Our Sheffield work is mostly in Ranmoor, Fulwood, Dore, Totley, Ecclesall and Nether Edge, for clients who value a finished result and a single accountable team over the cheapest quote.
Nether Edge and parts of Ranmoor are conservation areas, and stone-built houses usually need stone or carefully matched materials for an extension, which affects both cost and planning.
Questions
House extension in Sheffield: your questions
Can you build an extension on a sloping garden in Sheffield?
Yes. Sloping sites often need a retaining wall, a split level or steps, which we design in from the start along with the drainage.
Do you work in Sheffield?
Yes. We take on complete house extension projects across Sheffield, including Crookes, Walkley, Nether Edge, Ecclesall, Hillsborough and Dore, and in Ranmoor, Fulwood, Dore, Totley, Ecclesall and Nether Edge.
How much does an extension cost?
It depends on size, foundations, glazing and fit-out. Our online calculator gives a budget with VAT, and the survey turns it into a written estimate.
Do you arrange drawings and building regulations?
Yes. We arrange the drawings, structural calculations, planning or a lawful development certificate and building control.
Can I stay in the house during the build?
Usually yes. The back wall stays in place while the shell is built and is opened near the end.
