About Bromley
Bromley is one of our busiest areas. The mix of Victorian terraces in Bromley South, Edwardian semis around Bickley, and 1930s suburban houses across Bromley Common means we see a wide range of project types — from opening up dark galley kitchens in terraced houses to full loft conversions on semis with good roof height.
Postcodes we cover: BR1, BR2
Popular Services in Bromley
The most popular projects in Bromley are kitchen extensions on Victorian terraces (typically rear extensions of 15-20 sqm) and loft conversions on Edwardian and 1930s semis, which often have generous roof spaces ideal for dormer or hip-to-gable conversions. We also do a lot of garage conversions in Bromley Common, where integral garages on 1930s properties are underused and make excellent home offices.
Planning & Building Control in Bromley
Bromley Council is generally supportive of rear extensions under permitted development. For loft conversions, their planning team pays close attention to dormer size on conservation area properties around Bickley and Shortlands. We recommend applying for a Lawful Development Certificate to confirm permitted development rights before starting work.
Bromley Property Insights
Many Bromley properties built between 1920 and 1940 have solid walls rather than cavity walls, which affects insulation strategy and cost for extensions. The clay soil common in BR1 and BR2 postcodes can require deeper foundations (typically 1.2-1.5 metres) compared to areas with sandy subsoil, which adds £2,000-£4,000 to groundwork costs.
Common Projects in Bromley
Single-storey rear kitchen extension on a Victorian terrace
The most common big project in Bromley South. Victorian terraces along Bromley Road, Plaistow Lane, and the streets towards Sundridge Park have classic dark galley kitchens that get transformed by 4-5 metre rear extensions with bifold doors and roof lanterns. Cost is £50,000-£80,000 including structural steelwork, foundations on Bromley clay (1.2-1.5 metres typical, deeper near mature oaks around Sundridge Park), glazing, electrics, plumbing, and finishes. Build time 12-14 weeks. Bromley Council's permitted development process is straightforward for the standard 3-metre rear extension on terraces.
Hip-to-gable loft conversion on an Edwardian or 1930s semi
The standout project on Bromley's suburban streets. The Edwardian and 1930s semis around Bickley, Bromley Common, and Hayes have hipped roof structures that suit hip-to-gable conversions, creating a master bedroom with en-suite plus space for a home office or second bedroom. Cost is £55,000-£85,000 including structure, staircase, en-suite plumbing, electrics, plastering, and decoration. Build time 10-14 weeks. Bromley Council's planning team is particular about dormer proportions in conservation areas around Bickley and Shortlands — oversized designs are regularly refused.
Garage conversion to home office or annexe
Bromley has more garages worth converting than almost any other borough we work in. The 1930s semis and detached houses across Bromley Common, Hayes, and Bickley almost all have integral or attached garages that are used for storing bikes and boxes rather than parking cars. Single garage conversion £15,000-£25,000; double garage £25,000-£40,000 depending on whether plumbing and a kitchenette are included. Build time 4-8 weeks. The garage floor is typically 150-200mm below the house floor and we level up with insulated screed before the final flooring goes down.
Damp proofing on a pre-1930 property
Common on the older Victorian and Edwardian terraces in BR1, particularly around Bromley South where original slate damp-proof courses have failed after 100+ years. We diagnose the cause first (rising, penetrating, or condensation), inject a silicone-based DPC cream into the mortar course, allow 4-6 weeks for the wall to dry, then replaster with salt-resistant render. Cost £2,500-£5,500 including replastering. 20-year guarantee on chemical DPC work. The clay subsoil in BR1 and BR2 holds moisture, which makes proper diagnosis especially important — treating the wrong cause wastes money.

Frequently Asked Questions
- Why are Bromley foundations more expensive than in other boroughs?
- Two factors. First, the clay subsoil under most of BR1 and BR2 requires foundations of 1.2-1.5 metres, which is deeper than sandy subsoil areas. Second, properties near mature oak trees (particularly around Sundridge Park, Bromley Common, and the larger suburban gardens around Bickley) need deeper foundations of 1.5-2.0 metres or piled foundations to avoid movement from tree-root moisture extraction. Tree Preservation Orders are common on the larger properties, and removing trees for an extension is rarely permitted. Adds £3,000-£6,000 to typical extension cost compared with a tree-free site.
- Are dormer designs restricted in Bromley conservation areas?
- Yes, in Bickley, Shortlands, and parts of Plaistow. Bromley Council's planning team is particular about dormer proportions and regularly refuses oversized dormers that dominate the roofscape. Acceptable designs typically sit at least 200-300mm below the existing ridge, set back from the front and rear roof edges, and use materials matching the existing roof (slate or matching tiles). For permitted development loft conversions outside conservation areas, we always apply for a Lawful Development Certificate (£103) to give written confirmation from Bromley Council that the work meets the rules.
- Do solid walls on inter-war Bromley properties affect renovation cost?
- Yes, slightly. Many Bromley properties built between 1920 and 1940 have solid 9-inch brick walls without cavity insulation, unlike later cavity-wall properties. Adding insulation during a renovation means either internal wall insulation (which steals 50-75mm of internal floor area per wall) or external insulation (which changes the appearance and may need planning consent on conservation properties). External insulation isn't usually viable on the front elevation of period properties; internal insulation is typically used in habitable rooms only. Adds £3,000-£8,000 to a typical full renovation cost.
- How does Bromley Council handle permitted development applications?
- Generally efficiently. Bromley's planning team typically determines Lawful Development Certificate applications within 8 weeks (often faster). The £103 fee is standard. For conservation areas (Bickley, Shortlands, parts of Plaistow), the council reviews applications more closely and we design to their published guidelines from the outset. Bromley's pre-application advice service costs £150-£300 depending on project size and is useful for borderline cases. We handle the application process as part of every project rather than asking the homeowner to navigate it.
