“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.”
