House Extensions in Hackney
Hackney is one of London's most sought-after renovation markets. Dense Victorian terrace stock across Dalston, London Fields, Homerton and Clapton generates constant demand for high-quality extensions and loft conversions.
rcbGroup projectHouse Extensions in Hackney — what to expect
Hackney extensions are predominantly rear additions on the tight Victorian terrace plots. Side return extensions on end-of-terrace properties add valuable kitchen and dining space. The E8 and E9 market expects exceptional design quality — standard extensions won't cut through. Conservation areas in Dalston, London Fields and Clapton require planning permission in many cases.
Hackney property types
Victorian and Georgian terraces, converted warehouse and factory buildings, interwar council blocks. The property type affects which extension approach works best — we'll advise from the first call.
Common extension projects we deliver in Hackney
How we deliver extension projects in Hackney
Project review & site visit
We look at your Hackney property and any drawings you have, explain what's possible, the likely planning and Building Regulations route, and the risks — before you commit to anything. No obligation.
Design & planning support
We work alongside your architect or our preferred design partners to develop drawings that are buildable, compliant, and cost-effective. We flag planning and permitted development options early.
Itemised scope and price
You receive a detailed, itemised scope of works and an agreed price before we start, with exclusions and provisional sums shown. Variations are agreed in writing before any additional work begins.
Managed delivery
We coordinate trades, procurement and site logistics, with a single point of contact throughout — working to the requirements of London Borough of Hackney and Building Control.
Sign-off & handover
We coordinate the Building Control inspections needed for sign-off, then hand over your project documents — completion certificate, guarantees and manuals as applicable — with snagging and aftercare as set out in your contract.
Planning in Hackney
Hackney has extensive conservation areas across Dalston, London Fields, Clapton and Homerton. Many properties in these areas cannot use permitted development — full planning applications are required. Always verify with LBH Planning before proceeding.
