ABOUT OUR EXTENSION SERVICES
Tailored House Extensions Built
Around Your Home
At The Construction Collective Ltd, we design and build bespoke house extensions for homeowners across Barnet, Finchley, Whetstone, Totteridge, Mill Hill, Hendon, Golders Green and the surrounding North London areas.
Whether you're planning a rear extension, side return extension, wraparound extension or a large open-plan kitchen extension, our experienced team manages every stage of the project from initial consultation through to completion.
Unlike many contractors, we understand the challenges that come with extending properties in Barnet. From Victorian and Edwardian homes to 1930s family houses and modern developments, every property requires a tailored approach to design, planning and construction.
Our team works closely with homeowners, architects, structural engineers and building control officers to ensure every extension is built to the highest standards of workmanship, compliance and finish.
