Loft Conversions
We specialise in creating functional living spaces through dormer, hip-to-gable, mansard, and L-shaped loft conversions. Our process includes architectural planning, structural modifications, and finishing touches tailored to client needs. These projects typically add a double bedroom with bathroom or two smaller rooms while maintaining compliance with building regulations.
Extensions
Our team delivers rear, side, wrap-around, and double-storey extensions designed to enhance living space and property value. We handle all aspects from initial design and planning permission to construction, with projects typically costing between 35,000 and 65,000 depending on complexity and specifications.
Renovations
We revitalise properties through comprehensive refurbishments including kitchen and bathroom installations, painting, carpentry, and structural improvements. Our approach combines architectural expertise with skilled trades to modernise spaces while preserving structural integrity and meeting client timelines.

We transform empty plots and outdated buildings into bespoke residential properties. Our full-service process covers planning, design, and construction phases, ensuring seamless execution from concept to completion with a focus on quality materials and regulatory compliance.

Cant express how happy I am with the quality of the building work provided by Chelebi builders. Recently got a loft conversion carried out and was impressed how quickly they could turn around such a project in so little time without compromising quality. Highly recommended for any work needed around North London area.

Fantastic builder, was luckily introduced 10 years ago and been using them ever since. Always honest, always positive, nothing too much trouble. My entire family plus neighbours and all their family have been using them too, all by word of mouth. They don't need a google review, they get recommended, but it's the 21st century so here we are. Highly recommend!

We recently had ground floor extension done and after meeting a few builders we decided on using Chelebi Builders. From the initial quote to the finish build the whole team were always accommodating and very professional. We were living within the property during the build and the team always made sure we had facilities to carry on living as normal. We love our new space and would have no hesitation using Chelebi Builders in the future.
