A practical route from first idea to finished space

Start with your property

Tell us what is not working in the current layout and what you want to change. Your postcode, photographs and any existing drawings help us understand the scope before a survey.

Agree the design and responsibilities

Plans, structural calculations, approvals and the finish specification need coordinating. Confirm what is included, what is excluded and who is responsible for each stage before committing to construction.

Build to a clear scope

A useful quotation describes the actual work, not only a headline price. Discuss access, protection of the occupied house, the programme and how changes will be agreed. Keep inspection and completion records with the property documentation.

Plan your budget with better information

Explore our loft conversion cost guide, including a real £55,000 Sheffield dormer breakdown, and the house extension cost guide. These help you ask the right questions; a measured survey and agreed specification are needed for your own quote.

Frequently asked questions

Which service page should I start with?

Use the loft, extension or steelwork page for the work you are planning. If the project combines several services, describe the whole scope in one enquiry.

Can I enquire before I have drawings?

Yes. Explain the space you need and share photographs or a sketch. We can discuss the next steps towards a survey, design and quotation.

Do you provide a fixed online starting price?

No universal figure can account for every property. Structure, access, approvals and specification need assessing before a reliable project quotation can be given.

Talk to us about your property

Tell us where the property is, what you want to change and whether you have drawings. We can discuss the next practical step and arrange a survey where appropriate.
