Frequently asked questions.
Answers to the questions we're asked most. For anything else, contact our team.
Do I need planning permission?
Often not, but it depends on the house, its history and where it is. In England, a single-storey rear extension of up to 3 m (4 m on a detached house) can usually go ahead as permitted development, and up to 6 m (8 m detached) through the council's prior approval process. Most rear dormers within 40 m³ (terraced) or 50 m³ (other houses) are also permitted. Conservation areas, listed buildings and removed rights change the answer. We confirm the position at survey, and a Lawful Development Certificate gives you formal proof.
Do I need building regulations approval?
Almost always for an extension, a loft conversion or a garage converted into living space, even when planning permission isn't needed. Work is inspected by local authority building control or a registered building control approver. Keep the completion or final certificate, because you'll need it when you sell or remortgage.
What is a party wall notice?
If work affects a shared wall, is built on the boundary line or involves digging close to a neighbour's foundations, the Party Wall etc. Act 1996 may apply. As the building owner, you serve the notice: generally two months before work to a party wall, and one month before excavation or a new wall on the boundary line. We flag it at survey and can coordinate with a party wall surveyor.
Who is responsible for health, safety and compliance?
On domestic projects, the client's duties under the CDM Regulations 2015 normally pass to the contractor or principal contractor. The Building Regulations also set out dutyholder roles, including a principal designer and principal contractor on projects with more than one contractor. We confirm who holds each role in writing before work starts.
How do you price a job?
After a site visit, not from a guess over the phone. You receive a written, itemised quotation that shows what is and isn't included.
Where do you work?
We are based in Houghton le Spring and work across the North East: Tyne and Wear, County Durham, Northumberland and Teesside. Our wider catchment takes in Yorkshire, the Humber, Lincolnshire, Greater Manchester, Lancashire and Cumbria.
Will you travel outside the North East?
Yes. We'll listen to any project, anywhere in the UK, and we have delivered work as far as Amsterdam. Tell us what you're planning and we'll have an open conversation, with no obligation on either side.
Do you take on commercial and public-sector work?
Yes. We welcome enquiries from businesses, developers, housing providers, schools and public bodies. Send us your scope, specification or tender documents and our team will respond.
Is there a guarantee?
Your quotation sets out the terms for your project. Work booked through Checkatrade may also qualify for the Checkatrade Guarantee of up to £1,000. It is discretionary and subject to Checkatrade's terms.
Do you take on smaller projects?
Yes. Alongside larger projects we carry out structural openings, wall tie replacement, brick and concrete repairs, partition walls and refurbishments.
What happens after I send an enquiry?
Our project manager reviews it and contacts you to discuss the project and arrange a site survey. Nothing is booked until you're ready.

From a single room to a major development, tell us what you have in mind. There is no obligation on either side.
