Recent house extensions in Sheffield and Rotherham

At Totley Brook Road, we extended a stone-built home in Totley Brook, removing internal walls and installing bi-fold doors to create a light-filled, open-plan living space finished to complement the original house. At Chandler Grove in Treeton, a double side extension and single-storey rear extension, combined with a full knock-through and refurbishment, created a larger kitchen and dining area that opens onto the garden through bi-fold doors.

Both projects show how a well-planned extension can change the way a whole home works, not just add floor space. If you are at the early stages, our guides to where to start with a house extension and what to consider when planning an extension are a good place to begin.
Frequently asked questions
An extension is a significant investment in your home, so it is natural to have questions before you begin. These are the questions we are asked most often by homeowners in Sheffield and nearby areas including Rotherham, Doncaster, Barnsley and Chesterfield.

How much does a house extension cost?

The cost of an extension depends on its size, structure, glazing, specification and how much of the existing house is altered, so we price every project individually once we understand your plans. Our article on why cost per square metre can be misleading explains how to think about your budget.

Do I need planning permission for an extension?

Some extensions can be built under permitted development rights, while others need full planning permission, and almost all need Building Regulations approval. The right route depends on the size, height and position of the extension and the property itself. We manage every stage of your project, so you have clear guidance on approvals before work begins.

Can I stay in my home while the extension is built?

In most cases, yes. There may be short periods of disruption, particularly when the extension is opened up into the existing house or the kitchen is replaced, so we plan the programme carefully and keep you informed at every stage. Our clients at Chandler Grove told us the team ensured minimal disruption throughout.

What should I look for in an extension builder?

Look for a builder with completed projects you can see, clear communication and recognised accreditations. We are Constructionline Gold and CHAS members, and you can read reviews from our clients. Our guides to the signs you are hiring the right builder and how the right builder can transform your extension explain what to ask.

What types of extension do you build?

We build single and double-storey extensions, side and rear extensions, kitchen and living space extensions and more ambitious designs with extensive glazing and double-height spaces. Many projects also include internal alterations or a wider property refurbishment. See the house extension trends we are seeing across Sheffield and Yorkshire for inspiration.
