Structural alterations for Lewisham period homes

The bay-fronted terraces around SE6, SE23 and SE26 present a familiar set of structural jobs: forming a wide opening into a rear closet wing, cutting a new doorway through a solid brick wall, replacing tired or overloaded floor joists, and occasionally underpinning where old foundations have moved on Lewisham's clay-rich ground near Forest Hill and Blackheath.

Every one of these begins with a structural engineer's design. New and enlarged openings are formed with a steel beam or lintel bearing onto padstones, joists are specified to the correct span and grade, and underpinning is carried out in controlled sequenced bays. We prop, then work, then load, so the SE8 or SE13 home is never left unsupported at any stage.

Getting it signed off in Lewisham

Structural alterations inside your home fall under the Building Regulations, so Lewisham Council's building control inspects the propping, the beam bearings and the finished work rather than any planning department. Planning only enters the picture for exterior changes in a conservation area or to a listed building, which we will flag clearly if your Blackheath or Telegraph Hill property is affected.

Where an opening or underpinning affects a wall shared with the neighbouring terrace, the Party Wall Act applies and we serve notice on the adjoining owner first. We coordinate the engineer, the party wall notices and the building control inspections as one package, keeping the paperwork straight so your alteration is legitimate, certified and ready to build on.

Do structural alterations in Lewisham need building regulations approval?

Yes. Structural alterations in Lewisham, from new openings and steel beams to underpinning, are notifiable and must be designed by a structural engineer and signed off by building control. Planning permission is only needed where the work affects the exterior or a listed or protected building. We handle the approvals for you.

Yes. A large share of Lewisham's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each structural alterations around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.

Usually no. Internal structural work such as new openings, replacement joists or underpinning is controlled under the Building Regulations, and Lewisham Council's building control signs it off, not planning. Planning permission only applies to exterior work in a conservation area or to a listed building. We identify which rules apply to your specific SE-postcode property before we start.
