Extension & full refurbishment
Prestige completed an extension and complete house refurb for us and we couldn’t have been more pleased. The job was completed on time and to the agreed price to a brilliant standard.
Turn unused roof space into a comfortable bedroom, office or bathroom with coordinated loft-conversion building work across Cambridge and Cambridgeshire.
Every roof is different. The right design needs to account for headroom, the existing structure, safe access, insulation, fire safety and the rooms below.
Prestige builds to the approved architectural and engineering design, coordinating the agreed structure, roof alterations, stairs, building services and internal work so each part comes together in the right order.
Tell us how you would like to use the space and share any drawings, measurements or roof photographs you already have.
A loft conversion often runs alongside other work. Where new space is also being added at ground level, see our extensions page; where a gable or chimney needs new masonry, our brickwork page. We convert lofts across Cambridgeshire, including Great Shelford, Histon, Trumpington and Milton. Our full range of work is listed on the services page.
Planning and quotation guidance: Read our Planning Permission Guide, Permitted Development Guide and Builder’s Quotation Guide. For budgets, see our Loft Conversion Costs guide.
There are three common answers and the roof usually decides which one applies. A rooflight conversion is the cheapest and least disruptive, but it adds no volume, so it only works where the head height is already there. A dormer conversion builds out from the rear slope and creates head height where there was none, which is why it is the most common. A hip-to-gable conversion applies only to houses with a hipped roof and gives the most room of the three, usually paired with a dormer. Each page sets out what is actually involved and what tends to go wrong.
Tell us what you want to achieve, and send whatever you already have. Photos and drawings help, but they are not essential to start — plenty of projects begin with a description and a site visit.




Written project terms - Scope agreed before work starts
The agreed loft-conversion scope can include:
For a clear loft-conversion price, the following information is especially useful:
We aim to respond to every enquiry within one working day.
"*" indicates required fields
The work is planned around the roof structure, approved design, agreed scope and written contract before construction begins.

Share the property address, a short brief and any drawings, measurements or loft photographs you already have.
We look at headroom, access, structure, fire-safety requirements and the approved information before preparing a clear quotation.
The scope, costs, allowances, exclusions, contract, payment stages and build sequence are agreed.
The work follows the approved project documents and agreed build plan, with changes recorded before they proceed.
The completed work is inspected, snagging is addressed and the project is handed over with the applicable information.
Learn more about the loft conversion process with our answers to the key questions.
A suitable loft conversion can add practical rooms within the existing roof space. The final layout and specification depend on the structure, access, fire strategy and approved design.
Planning requirements depend on the property, location and proposed roof alterations. Some loft conversions may fall within permitted development limits, while others require an application. Building Regulations and structural information still need to be addressed. Check the current position with the relevant local authority or planning professional before work starts.
Timing depends on the roof structure, conversion type, access, structural work, services and finishes. Once the drawings, approvals and agreed scope are available, the quotation can identify the anticipated sequence and duration.
Roof shape, usable head height, staircase position, structure and planning constraints all affect the workable design. An architect or structural designer can develop the scheme; we then use that information for pricing and construction.
We do not provide property-valuation advice or promise a particular increase in value. A local chartered surveyor or qualified valuer can advise on the likely effect for a specific property.
