Summer Houses Builders in Downham for tailored garden rooms

Add a dedicated workspace, hobby room or peaceful retreat with a professionally built summer house designed for your garden. We regularly work around BR1, including homes near Downham Fields and routes towards Grove Park. Every build is tailored to your layout, privacy needs and how you want to use the space. Expect clean lines, solid joinery and a finish that looks right from day one.

Downham’s established residential estate includes 1920s cottage homes, 1930s semis and post-war housing, often with practical rear gardens and side access. We design summer houses to suit these plots, whether you want a compact corner build or a larger room for family use. Our team considers neighbouring boundaries, existing patios and drainage so the new structure sits comfortably within the garden. If you’re close to Catford or Bellingham, we’ll match the style to your property and surroundings.

From the first survey to the final interior finishing, we manage the full build: foundations, framing, insulation options, electrics and tidy handover. You’ll receive clear specifications, realistic timescales and planning advice before work starts. We protect lawns, keep access routes clear and keep you updated at each stage. Local homeowners choose us for dependable workmanship, transparent communication and a long-term guarantee.

Summer Houses Builders FAQs - Downham

How much do summer houses cost in Downham?

Costs vary by size, specification and access. As a guide, a small, uninsulated timber summer house with a simple base may start around £3,500–£6,000. A mid-sized bespoke build with insulation, double glazing and electrics is often £7,000–£14,000. Larger garden rooms with higher-end cladding, heating-ready electrics and full interior finishing can reach £15,000–£30,000+. We provide a detailed, itemised quote after a site visit.

How long does it take to build a summer house?

Most projects take 1–3 weeks on site, depending on the base, size and finishing level. A straightforward build with a prepared area can be completed in around a week, while insulated garden rooms with electrics, plasterboard, flooring and fitted storage take longer. Lead times for bespoke joinery, glazing and cladding can add 2–6 weeks before installation. Weather, access and any ground preparation also affect the schedule.

Do I need planning permission for a summer house in the London Borough of Lewisham?

Many summer houses fall under permitted development, especially if they’re single-storey, within height limits and used as incidental garden space. However, rules can change if you’re near boundaries, in a constrained plot, adding a veranda, or planning to use it as self-contained accommodation. We provide planning advice, check key constraints and can recommend when a formal application is sensible. If needed, we’ll help you prepare the information Lewisham Council typically requests.

What guarantees do you provide on summer house builds?

We back our workmanship with a 10-year warranty covering the build structure and installation, including the base and key construction elements. Manufacturer warranties apply separately to items such as doors, windows, cladding systems and electrical components. We’ll explain what’s covered in writing and how to maintain finishes such as timber treatments. If anything settles or needs adjustment after completion, we respond promptly and put it right.

What material and design options are available?

You can choose traditional timber summer houses, contemporary garden rooms with clean lines, or hybrid designs that suit both period and modern homes. Popular options include tongue-and-groove timber, composite cladding, EPDM or felt roofing, double glazing, and upgraded insulation for year-round comfort. Inside, we can add plasterboard, flooring, lighting, sockets and storage. Our summer houses builders Downham area team will guide you on durability, maintenance and the best layout for your garden.
