Our Testimonial

Trusted by Homeowners Across Glasgow

"LK Design Construction transformed our dusty attic into a stunning master bedroom. The team was punctual, polite, and the finish quality is hotel-standard. They handled all the council permits too, which was a huge relief."

    Sarah Jenkins

    Homeowner, Ealing

    "We hired them for a rear kitchen extension. Despite the tight access to our garden, they managed everything perfectly. The project was completed on time and exactly on budget. Highly recommended for complex London builds."

      David & Emma Ross

          Project Planning & Costs

          Loft conversion costs in Glasgow typically range from £40,000 to £80,000+, depending on the size, type, and complexity of the project. Simpler conversions (such as Velux/rooflight) can start from around £40,000–£50,000, while larger dormer or hip-to-gable conversions usually fall between £50,000 and £70,000+. High-end or more complex projects like mansard conversions can exceed £80,000.

          Construction & Process

          Yes, for almost all structural work (like removing chimney breasts or adding a loft), a structural engineer is required to calculate the weight loads and specify steel beams. This is crucial for Building Regulations approval.
