Builders in Lewisham

Lewisham (SE13 and SE6) runs from the older Victorian and Edwardian streets around Blackheath and Hither Green through to the more recent developments near Lewisham town centre and Catford. It is an area where property values have risen steadily, making the case for investing in an extension or loft conversion stronger than ever. Albert Construction works regularly in the area on house extensions, loft conversions, kitchen installations, and bathroom refits. Victorian terraces around Hither Green and Lee are well-suited to rear extensions that open up the kitchen and connect the ground floor to the garden. The same properties usually have enough roof pitch for a rear dormer loft conversion — creating a bedroom and en-suite at the top of the house without touching the garden footprint. Blackheath has significant conservation area coverage, and extensions or roof alterations in these streets need full planning consent rather than permitted development. We manage the application process directly and have experience working within Lewisham Council's design guidance. Edwardian semis in Catford suit double-storey extensions — a rear extension across two storeys gives two new rooms for less cost than two separate projects. Party wall agreements are always required for terraced and semi-detached properties, and we handle all the notices and paperwork as standard.

Operating locally across Lewisham, we have extensive experience extending and renovating Victorian terraces, Edwardian semis, converted flats and 1930s semis. Whether your property is near Lewisham Shopping Centre or Blackheath, we understand the local architecture perfectly. Lewisham's Victorian and Edwardian terraces offer excellent loft and rear extension potential.

Frequently Asked Questions

Are there planning restrictions in Blackheath or Hither Green?
Blackheath has significant conservation area coverage where permitted development is restricted for roof alterations and extensions. Hither Green and Lee are generally more straightforward for permitted development. We check the planning status of your specific property during the free site survey and advise on whether a planning application is needed before any work starts.
What type of extension suits Victorian terraces in Lewisham?
Rear extensions are the most common and impactful improvement for Victorian terraces in SE13 and SE6 — opening up the kitchen and connecting the ground floor to the garden. The same properties usually have enough roof pitch for a rear dormer loft conversion. Combining both projects saves significantly on scaffolding and reduces total disruption.
How much does a loft conversion cost in Lewisham?
A rear dormer loft conversion in Lewisham typically costs £36,000–£52,000. A hip-to-gable conversion on an Edwardian semi ranges from £44,000–£62,000. The exact price depends on the roof structure, access, and specification. Our quotation is fixed-price and itemised — the number we quote is the number you pay.
Do you work on Edwardian semis in Catford?
Yes. Edwardian semis in Catford and Bellingham are among the best candidates for double-storey extensions in South East London — wide-fronted, solid brick, and with rear gardens that typically accommodate a 3–4 metre extension without difficulty. Many qualify under permitted development and the value uplift is strong in this part of SE London.
