Design & Build Contractors Delivering Considered London Homes
Dulwich homeowners have high expectations — and rightly so. The area’s period housing stock, tree-lined streets and proximity to the park set a standard that building work needs to meet, not just in quality but in sensitivity to the surroundings. At S&M Solutions, we’ve been delivering extensions, loft conversions and full renovations for Dulwich homeowners for years — working with the grain of these properties rather than against them. Whether you’re extending a Victorian terrace in East Dulwich or renovating a period home near the park, our team handles every stage with the same attention to detail and building standards that the area deserves.
We Know Dulwich
Dulwich sits across two postcodes, SE21 and SE22, and covers a range of property types, from Victorian and Edwardian terraces in East Dulwich to larger period homes closer to Dulwich Village. A significant portion of the area falls within or next to conservation areas, and many properties are on the Dulwich Estate, which carries its own covenants and restrictions on top of standard planning rules.We’ve worked across both parts of Dulwich and understand what that means in practice: which projects need full planning applications, which qualify under permitted development, and how the Dulwich Estate’s own approval process works alongside the council’s. That knowledge saves time, avoids costly mistakes, and keeps your project moving without unnecessary delays.Our work in Dulwich covers house extensions, loft conversions, full home renovations and design and build projects. Every project is managed under one contract with our own in-house team: no handoffs, no gaps in accountability, no surprises halfway through.
1: Do you need Dulwich Estate approval for building work? If your property sits within the Dulwich Estate, you'll need approval from the Estate's surveyor in addition to standard planning permission from Southwark Council. The two processes run separately and both need to be satisfied before work can begin. We're familiar with the Estate's requirements and factor this into the programme from the outset.
2: Which council covers Dulwich? Most of Dulwich falls under the London Borough of Southwark. Parts of West Dulwich come under Lambeth, and some streets towards Sydenham Hill and Forest Hill fall under Lewisham. We confirm the correct planning authority at the site visit and manage the application from there.
3: Do you work on period properties in Dulwich? Yes — Victorian and Edwardian terraces make up a large proportion of the housing stock across SE21 and SE22. We understand the structural characteristics common to these property types and have experience working within Dulwich's conservation area constraints.
4: What building services do you offer in Dulwich? House extensions, loft conversions, full home renovations and design and build projects across Dulwich SE21 and SE22 — all managed under one contract with our own in-house team covering design, structural coordination and construction.
