Frequently Asked Questions — Dulwich
How much does a premium extension cost in Dulwich?
Premium extensions in Dulwich typically range from £2,500-£4,500 per square metre given the high specification required for conservation area properties. A bespoke rear extension averages £85,000-£185,000, while a luxury loft conversion ranges from £65,000-£120,000. Alstruct provides detailed quotations sensitive to Dulwich's unique architectural requirements.
Can I extend my property in the Dulwich Village conservation area?
Extensions within Dulwich's conservation areas require careful planning and often full planning permission. The Dulwich Estate also imposes its own design guidelines. Alstruct has extensive experience working within these dual requirements, liaising with both Southwark Council and the Dulwich Estate to achieve approvals for sympathetic, high-quality extensions.
Does Alstruct understand the Dulwich Estate's building requirements?
Yes. The Dulwich Estate has specific architectural guidelines that go beyond standard planning requirements. Alstruct's design team is thoroughly familiar with these standards and ensures all proposed works align with the Estate's expectations for materials, proportions, and overall design quality.

Dulwich has Victorian and Edwardian villas and terraces around Dulwich Village, East Dulwich and West Dulwich, with 1930s houses towards Sydenham Hill. Kitchen extensions with garden glazing and side-return infills are the common Dulwich projects; basements are popular on the larger Village houses.
Budget guidance for Dulwich: expect £2,500–£4,000 per m² for a single-storey extension, which puts a 25–30 m² kitchen extension at £75,000–£120,000; two-storey and wraparound schemes are priced on the structure involved (see our house extension cost guide). Most of Dulwich is within the Dulwich Estate Scheme of Management, which requires estate consent on top of Southwark Council planning, and the Village is a conservation area. Where approval from Southwark Council is needed, our in-house design team prepares and submits the application.
Loft conversions in Dulwich
Dulwich roofs suit rear dormers and, in the Village, mansards or flush dormers; many Edwardian houses have the height for a two-room conversion.
Typical London figures are £25,000–£45,000 for a Velux conversion, £45,000–£75,000 for a dormer and £60,000–£100,000+ for a mansard (details in our loft conversion cost guide). Every Dulwich loft quote follows a measured survey of the roof, head height and stair position, and includes Building Regulations sign-off, fire doors and structural calculations.
Renovations and refurbishment in Dulwich
Dulwich renovations are usually full refurbishments of period houses, restoring features while adding modern kitchens, bathrooms and services. Typical Dulwich refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. Budgets are set out in our renovation cost guide; in Dulwich, as everywhere, we work to a JCT contract, a written specification and a 10-year workmanship warranty.
