Builders in Harrow

Harrow is a borough of real variety — from the Victorian terraces around South Harrow and Rayners Lane to the larger detached homes near Harrow on the Hill and Pinner. Albert Construction works across the whole area, carrying out house extensions, loft conversions, kitchen installations, and full bathroom renovations. The hilly terrain in parts of Harrow means foundations sometimes need more engineering thought than a flat site — our structural engineer comes out on every survey to assess ground conditions and design accordingly. For most terraced and semi-detached properties, party wall agreements are required before work starts on any shared boundary, and we walk every client through that process clearly before anything else happens. Whether you are looking to open up a narrow Victorian kitchen, add a dormer loft bedroom, or extend the rear of your 1930s semi into the garden, our in-house team handles every trade — plumbing, electrics, plastering, tiling, and joinery. One contact, fixed price, 2-year guarantee.

Operating locally across Harrow, we have extensive experience extending and renovating Victorian terraces, 1930s semis, Edwardian homes and modern estates. Whether your property is near Harrow on the Hill or Harrow School, we understand the local architecture perfectly. Harrow's hilly terrain and mature trees mean careful foundation design and drainage planning for extensions.

Frequently Asked Questions

Does Harrow's hilly terrain affect extension foundations?
It can. Properties on sloping ground — particularly around Harrow on the Hill — sometimes need deeper foundations or stepped footings to reach stable ground. Mature tree roots near the building line can also affect foundation depth. Our structural engineer assesses ground conditions during your site survey and designs the foundations accordingly.
Can I extend a Victorian terrace near Harrow town centre?
Yes. Victorian terraces around Harrow town centre often benefit from rear extensions and loft conversions. Side-return infills are popular for opening up narrow kitchen layouts. You will likely need a party wall agreement with your neighbours, which we guide you through.
How long does a kitchen fitting take in Harrow?
A typical kitchen fitting takes 2-3 weeks including strip-out, plumbing, electrics, unit installation, worktop fitting, tiling, and finishing. If the kitchen is part of a larger extension project, we schedule the kitchen install towards the end so the new space is watertight and plastered first.
What is included in your fixed-price quotation?
Everything. Our quotation covers all materials, labour, structural engineering fees, building control fees, skip hire, and scaffolding. There are no hidden extras. If something unexpected arises — like discovering asbestos or rotten joists — we discuss it with you before any additional costs are agreed.
