Hackney is one of East London's most dynamic and sought-after residential areas, having undergone one of London's most significant property value transformations over the past two decades. The London Borough of Hackney now encompasses some of the most desirable Victorian terraced housing in East London across areas including Hackney Central E8, London Fields E8, Dalston E8, Stoke Newington N16, Clapton E5 and Homerton E9. The combination of large Victorian terraced houses, excellent transport links and strong buyer demand makes Hackney one of East London's most active areas for house extensions. LCCL Construction delivers house extensions across Hackney and all of East London as part of our complete design and build service.
House Extensions Hackney: Best Types for Local Properties
Hackney's large Victorian terraced houses are ideally suited to side return extensions, rear extensions and wraparound extensions. Many Hackney Victorian terraces have a side return alley alongside the rear — making the wraparound extension the outstanding choice for creating a large open plan ground floor. Double storey rear extensions are increasingly popular across Hackney for families needing space on both floors.
