The service
House extensions across East London
Chenko Builders has been delivering high-quality house extensions across East London, working with homeowners in Hackney, Stratford, Ilford, Canary Wharf, Greenwich, Poplar, Romford and Walthamstow. Whether you are looking for a single storey rear extension to open up your kitchen and living space, a double storey to add bedrooms, a side return to reclaim wasted side passage, or an L-shaped wraparound to transform the rear of your home, we handle the complete build from groundworks to final decoration. As an East London based contractor, we understand planning rules across Tower Hamlets, Newham, Redbridge and Waltham Forest. Every extension is priced with a fully itemised quote so you know exactly what you are paying for before a single brick is laid. No vague estimates, no surprise charges mid-build — just honest, reliable building work.

Common questions
Frequently asked
We build single storey rear extensions, double storey, side return, L-shaped and wraparound extensions across East London boroughs including Hackney, Stratford, Greenwich and Ilford.
Most single storey rear extensions fall under permitted development and do not require planning permission as long as they stay within size limits. We advise on this during your free site survey.
A typical single storey rear extension takes 8 to 12 weeks from start to finish depending on size and specification. We agree a timeline before work begins and stick to it.
