Property Renovation Tip for Streatham Homeowners
Streatham's housing stock is a mix of construction types, which means renovation approaches vary from house to house. The Edwardian terraces have solid brick walls and slate roofs, while the 1930s houses have cavity walls and concrete tile roofs. The solid-walled Edwardians need different insulation treatment from the cavity-walled 1930s properties. We assess each property on its merits rather than applying a one-size-fits-all approach — the survey determines the spec, not a template.
What a Streatham property renovation typically covers
Three patterns cover most of what we run for full renovations in SW16. Edwardian terrace renovation around Streatham Hill is the most common project. The Edwardian terraces along Streatham Hill, Mount Nod Road, and the streets running off Streatham High Road have solid 9-inch brick walls (or early cavity walls on the later 1900s-1910 properties), slate roofs, original sash windows, and high ceilings (typically 2.7-2.9 metres on the ground floor). Scope includes complete rewire to BS 7671, full replumb including replacement of original lead supply pipes and corroded cast-iron soil stack, structural opening-up of the ground floor, sash window restoration where original, lime plaster repairs, new kitchen and bathrooms, and complete decoration. Cost is £90,000-£160,000 depending on size. Build time 14-20 weeks. 1930s semi renovation around Streatham Common and Streatham Vale is the second pattern. Cavity-wall construction (typical of 1925-1939 properties), regular layouts, suspended timber ground floors, and concrete-tile roofs. The construction is sound and predictable — different specification from the solid-walled Edwardians. Cost is £100,000-£170,000. Build time 16-22 weeks. Combined renovation plus loft conversion is the third pattern, common where the family needs a fourth or fifth bedroom. Single coordinated project covering the loft work plus the rest of the refurbishment. Cost is £140,000-£230,000. Build time 20-26 weeks. Significant economies vs separate projects: typically 10-15% cost saving and 4-8 weeks shorter total programme.
Streatham-specific renovation detail
Three Streatham factors regularly affect renovation scope. Mixed Edwardian solid-wall vs 1930s cavity-wall stock. Streatham housing splits broadly between pre-1910 solid-wall Edwardians and 1925-1939 cavity-wall semis. The thermal upgrade approach is fundamentally different. Solid-wall Edwardians (U-value around 1.7 W/m²K untreated) need internal wall insulation during the renovation — typically 50-75mm rigid PIR with vapour control layer and plasterboard skim, achieving U-value 0.30-0.35 W/m²K. Steals 75-90mm of internal floor area per external wall. Cavity-wall 1930s semis (U-value around 1.0 W/m²K untreated) take cavity-fill insulation — bonded bead or mineral wool injection through 22mm holes drilled in the mortar joints, achieving U-value 0.30-0.40 W/m²K. No internal floor area lost. Cost is £1,200-£2,000 versus £120-£180 per square metre for internal insulation. Streatham Common conservation area. The Streatham Common conservation area covers a substantial area south-east of the common including some of the larger period villas. Within it, exterior alterations need sympathetic design — front-facing changes (window replacement, render colour, roof material) need conservation review and Lambeth can refuse retrospective consent. Internal renovations are unaffected. We check the boundary on the Lambeth planning portal at the survey before quoting any external work. Lambeth Council process. Streatham falls under Lambeth Council. Lambeth applies its design guidance individually rather than as a tick-box exercise — the conservation team and case officers review applications against published policy. The process tends to be slightly slower than Wandsworth but consistent and predictable. We design to Lambeth's published guidelines from the outset rather than testing the limits, which means applications typically get approved without revisions. Services on pre-1980 properties typically need full rewire to BS 7671 (£4,500-£9,000) and full replumb (£6,000-£11,000) with hot water upgrade to combi or unvented cylinder (£2,500-£4,500, BS 7593 commissioning).
Project management on a Streatham property renovation
A Streatham full renovation typically involves 12-16 different trades over 14-22 weeks: demolition, structural engineering, drainage, electrics (NICEIC), plumbing, gas (Gas Safe), plastering, joinery, kitchen fitting, tiling, flooring, glazing (FENSA), painting, decoration. We assign one project manager from survey through handover with photo updates throughout the build. Streatham falls under Lambeth Council. Internal renovations do not need planning permission. The Streatham Common conservation area affects external alterations only. Lambeth has Article 4 directions in some Streatham streets that mainly affect front-of-property changes (cladding, window replacement, front-facing alterations) — we verify the planning status on the Lambeth planning portal before quoting. Building Regulations apply for the rewire (BS 7671 under Part P), structural opening-up (Part A), drainage (Part H), thermal performance (Part L: U-value 0.18 W/m²K for new walls and roof, with internal wall insulation specified to 0.30-0.35 W/m²K on existing solid walls), and any unvented cylinder (BS 7593 commissioning). Lambeth Building Control charges £450-£700 for a renovation inspection process. Inspections happen at structure, drainage, insulation, and completion stages. Fixed-price contracts cover labour, materials, all fees, structural engineer calculations, FENSA registration, party wall surveyor coordination, conservation area applications where relevant, internal or cavity-wall insulation specification, and Building Control fees. The contract is signed before any work starts. Variations are quoted in writing before they are done.

Frequently Asked Questions
- How much does a Streatham property renovation cost?
- Edwardian terrace renovation around Streatham Hill runs £90,000-£160,000 depending on size and specification. 1930s semi renovation around Streatham Common and Streatham Vale runs £100,000-£170,000. Combined renovation plus loft conversion runs £140,000-£230,000 for a single coordinated project. Internal wall insulation on solid Edwardian walls is £120-£180 per square metre. Cavity-wall insulation on 1930s semis is £1,200-£2,000 for the whole property. Fixed-price contract before any work starts. The price doesn't change unless the specification does.
- How does the thermal upgrade differ between Streatham Edwardians and 1930s semis?
- Fundamentally different approaches because the wall construction is different. Pre-1910 Edwardians have solid 9-inch brick walls (no cavity) with U-value around 1.7 W/m²K. The only practical option is internal wall insulation — typically 50-75mm rigid PIR with vapour control and plasterboard skim, achieving U-value 0.30-0.35 W/m²K. Steals 75-90mm of internal floor area per external wall. Cost £120-£180 per square metre. Post-1925 semis have cavity walls with U-value around 1.0 W/m²K untreated. Cavity-fill insulation (bonded bead or mineral wool injected through 22mm holes drilled in the mortar joints) achieves 0.30-0.40 W/m²K with no internal floor area lost. Cost £1,200-£2,000 for the whole property. We assess each property at the survey rather than applying a template.
- Does the Streatham Common conservation area restrict my renovation?
- Only on external alterations, not internal work. The Streatham Common conservation area covers a substantial area south-east of the common including some of the larger period villas. Within it, front-facing changes (window replacement, render colour, roof material) need conservation review and Lambeth can refuse retrospective consent for inappropriate work. Internal renovations (rewire, replumb, structural opening-up, kitchen, bathrooms, plastering, decoration) are unaffected. Where original sash windows are being restored rather than replaced, the conservation team welcomes the approach. We check the boundary on the Lambeth planning portal at the survey before quoting any external work.
- Why hire All Well for a Streatham property renovation?
- Three reasons. First, we know the SW16 stock — solid-wall Edwardians around Streatham Hill versus cavity-wall 1930s semis around Streatham Common, the different thermal upgrade approaches, and the Streatham Common conservation area boundary. Second, full accreditation: NICEIC for electrical (BS 7671), FENSA for glazing, Gas Safe registered for boiler work, structural engineer calculations included, and Building Control sign-off on every project. Third, fixed-price contracts: the quote doesn't change unless the specification does. 57 verified Google reviews averaging 4.5/5. Office on Limes Avenue, SE20.
