Builders in Tooting, SW17
Tooting is one of South London's most dynamic and family-friendly neighbourhoods, where long tree-lined streets of handsome Victorian and Edwardian terraces offer outstanding potential for home improvements that deliver both extra living space and excellent property value uplift. Alstruct Ltd provides premium construction services across Tooting SW17, bringing skilled craftsmanship and intelligent design to every extension, conversion and renovation project.
The classic Tooting terrace — whether a bay-fronted Victorian or a generous Edwardian semi — typically sits on a deep plot with a sizeable rear garden, making it perfectly suited to a transformative rear extension. Our clients here commission open-plan kitchen-dining-living spaces with full-width skylights, bifold doors and premium finishes that redefine how their family uses the home. Loft conversions are equally popular, with dormer and hip-to-gable designs adding valuable bedroom and en-suite space. For those seeking a complete transformation, our whole-house renovations strip properties back to the shell and rebuild them to an exacting modern standard while retaining the period character that makes Tooting's housing stock so attractive.
Tooting falls within the London Borough of Wandsworth, widely regarded as one of London's most construction-friendly boroughs while still maintaining high design standards. Alstruct's design team manages planning applications to Wandsworth Council and Building Regulations submissions on every project.

Tooting is Victorian and Edwardian terraces around Tooting Bec, Tooting Broadway and Furzedown, with the Totterdown Fields cottage estate and 1930s semis towards Mitcham. House extensions in Tooting are mostly side-return and wraparound kitchen extensions on the terraces; the Furzedown houses have the plot depth for a full-width rear extension.
As a guide, a well-built single-storey rear or side-return extension in Tooting costs around £2,500–£4,000 per m² including structure, glazing and finishes, so a typical 25–30 m² kitchen extension lands between £75,000 and £120,000. Our house extension cost guide explains what moves the price. Totterdown Fields, Mellison Road and Streatham Park are among the conservation areas here, and Wandsworth's Local Plan keeps dormers to the rear, in matching materials. We confirm permitted development rights at the first visit and handle any application to Wandsworth Council through our design team.

Loft conversions in Tooting
Loft conversions in Tooting are usually L-shaped rear dormers over the back addition, giving a bedroom and en-suite; the Totterdown cottages have limited roof space so we survey first.
In London a Velux conversion costs £25,000–£45,000, a dormer loft with a bedroom and en-suite £45,000–£75,000 and a mansard £60,000–£100,000+; our loft conversion cost guide sets out what is included. We survey the roof structure, head height and stair position before we quote a Tooting loft, so the figure reflects the actual roof rather than an assumption.
Renovations and refurbishment in Tooting
Tooting refurbishments are typically full renovations of Victorian terraces and ground-floor flats, including structural openings and new bathrooms. Typical Tooting refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. Our Victorian terrace renovation cost guide gives realistic budgets, and every Tooting project runs on a JCT contract with a written specification and our 10-year workmanship warranty.

Common questions about building in Tooting
Do I need planning permission for an extension in Tooting?
Houses (not flats or maisonettes) keep national permitted development rights for a single-storey rear extension (3m attached, 4m detached, or 6m and 8m with prior approval) and most rear dormers (40 cubic metres on a terrace, 50 otherwise). Tooting and Furzedown are in Wandsworth Council. Conservation areas include Totterdown Fields, Mellison Road, Streatham Park on the Furzedown side, and the Heaver Estate and Culverden Road by Tooting Bec Common. There, side extensions, two-storey rear extensions, cladding and roof additions need permission. Article 4 directions on the Totterdown Fields and Heaver estates also control street-facing windows, doors, roofs, porches and front boundaries. See our permitted development guide.
What does Wandsworth Council expect for loft conversions in Tooting?
The size limits for a permitted development dormer are national, not Wandsworth's, but the council's own policy applies whenever an application is needed. Local Plan Policy LP5 keeps dormers and roof alterations to the rear, in matching or complementary materials. The Housing SPD (2016) usually accepts a rear mansard-style addition on a mid-terrace house between party walls if it is not clearly seen from the street, and prefers a rear dormer set below the ridge on end-of-terrace and corner houses. On the Totterdown Fields Estate, roof changes need permission under its Article 4 direction.
What does a side return extension cost in Tooting?
Most Tooting extensions are on Victorian and Edwardian terraces, and a side return extension there typically costs £65,000–£130,000 at mid to high specification, including VAT. The deeper Furzedown plots can take more, so the depth and the amount of glazing make the biggest difference. If a loft is planned too, a rear dormer is £45,000–£75,000 and an L-shaped dormer £55,000–£85,000, including VAT. Our Victorian side return extension cost guide explains what moves the price.
