Loft Conversions in Guildford.
Guildford's housing runs from Victorian and Edwardian terraces near the town centre to 1930s family homes in Merrow, Burpham and Onslow Village. Many have roof spaces with real potential for an extra bedroom, a study or a principal suite.

Our focus in Guildford.
Grand Innovations designs and builds loft conversions in Guildford. We assess the roof structure first, then recommend the type of conversion that suits your house, and manage the structural work, building regulations and fit-out as a single project.
As a design-and-build company we take on a limited number of projects at a time, so that every one gets the attention it deserves. If you are planning work on your Guildford home, we would like to hear about it.

What we deliver in Guildford.
- 01
Choosing the Right Conversion
Rooflight, dormer, hip-to-gable or mansard: the right type depends on your roof structure, the headroom available and how you want to use the space.
- 02
Structure & Staircase
Engineered steelwork, a safe and well-placed staircase, and floors and insulation built to current building regulations.
- 03
Bedroom & En-suite Fit-Out
Joinery, plumbing, electrics and finishes completed by one team, so the new floor feels part of the house.
- 04
Planning & Conservation
Many loft conversions can proceed under Permitted Development, but older Guildford streets include conservation areas where extra consent may be needed. We establish the position with Guildford Borough Council first.
Your questions, answered.

“Grand Innovations carried out our loft conversion and the experience was far smoother than expected for such a complex project. Conor was hands-on, knowledgeable, and always available when decisions needed to be made. The build quality is excellent. The stairs, insulation, carpentry, and finishes all feel high-end and carefully completed. What impressed us most was how well the different trades were managed and how much attention was paid to detail. The space now feels like it was always part of the house. A very professional team that takes real pride in their work.”
