Builders in Finchley

Finchley — covering N2, N3, and N12 — is one of North London's most established residential areas, with a housing stock that ranges from compact Victorian terraces in East Finchley to wide 1930s semis along the Finchley Road and larger Edwardian detached homes in the streets around Coppetts Road and Woodside Park. Albert Construction works regularly across all three Finchley postcodes, carrying out house extensions, loft conversions, full kitchen installations, and bathroom renovations. The 1930s semis that dominate much of central Finchley are well-suited to double-storey rear extensions — the rear garden is typically long enough, the structure is solid, and adding two storeys at once is far more cost-effective than doing it in two separate projects. Many of these properties also have the roof pitch for a hip-to-gable loft conversion with rear dormer, creating a large master bedroom suite at the top of the house. Victorian terraces in East Finchley suit rear and side-return extensions — particularly where the kitchen sits in the back reception room and the layout feels cut off from the garden. Most extension and loft work in Finchley qualifies under permitted development, but party wall agreements with neighbours are almost always required and we manage that entire process. One point of contact, fixed price, every trade in-house.

Operating locally across Finchley, we have extensive experience extending and renovating 1930s semis, Victorian terraces, Edwardian detached and converted flats. Whether your property is near Finchley Central or North Finchley High Road, we understand the local architecture perfectly. Large 1930s semis in Finchley suit double-storey extensions but often require party wall agreements with neighbours.

Frequently Asked Questions

What type of loft conversion suits a 1930s semi in Finchley?
A hip-to-gable conversion with a rear dormer is the most popular choice for 1930s semis in Finchley. It squares off the sloping side of the roof and adds a box dormer at the rear, creating a large master bedroom with en-suite. Many qualify under permitted development — no planning permission needed — and we confirm this during your free site survey.
Can I build a double-storey extension on a Finchley Victorian terrace?
Yes. Victorian terraces in East Finchley and North Finchley often have rear gardens that accommodate a double-storey extension. The ground floor adds kitchen-dining space and the first floor adds a bedroom — typically more cost-effective than doing two single-storey projects at different times. We handle structural engineer calculations, party wall notices, and building control as standard.
Do I need a party wall agreement for building work in Finchley?
For most terraced and semi-detached properties in Finchley, yes. Any extension or loft conversion that involves work on or near a shared wall or boundary requires a party wall notice to neighbours under the Party Wall Act 1996. We explain the process clearly and manage all notices and surveyor communications on your behalf.
How much does a house extension cost in Finchley?
A single-storey rear extension in Finchley typically costs £35,000–£52,000. A double-storey extension ranges from £52,000–£75,000. The exact price depends on the size, ground conditions, and your specification. Our quotation is fully fixed-price and itemised — the number we give you is the number you pay.
