About Gosai Construction Limited
Gosai Construction carries out home extensions, loft conversions, refurbishments, kitchens, bathrooms and garden projects across London and Greater London. It also lists plumbing, heating, boiler, electrical, carpentry, window and door, driveway and external rendering work.
The company says it has over 30 years of experience and is a family-run business based in North London. Its team includes qualified tradespeople and works alongside architects, surveyors and engineers.
Projects start with a consultation and design and planning, followed by implementation and a project handover. The company says it provides detailed quotes, clear communication and manages each phase of the work.
Every project is stated to have at least a 12-month guarantee. The team says it protects existing areas, plans work to reduce disruption and maintains a clean, safe site during kitchen projects.

What customers say
Gosai transformed our kitchen and bathroom with outstanding results. The team were professional, hardworking, and finished on time despite extra work. They kept everything spotless, and we couldn’t be happier.
Would recommend Gosai 100%! They delivered a high-quality decking job on a tight deadline with minimal disruption. Jimmy was fantastic — hardworking, tidy, and a pleasure to work with.
We’re so pleased with our new kitchen and flooring. The team were friendly, professional, and careful to minimise dust during the project. Shiv kept us updated throughout, and the final result is fantastic.
