From BR5 to BR6, we design and build summer houses that suit how Orpington homeowners actually use their gardens—home office, gym, studio or a calm retreat. Whether you’re near Orpington station or popping to The Walnuts Shopping Centre, we’ll plan a build that fits your plot and access. Expect crisp detailing, tidy workmanship and a structure that feels like a real extension of the home. Every project starts with a clear brief, site check and measured design.
Orpington’s mix of 1930s semis, detached houses and modern estates often comes with generous gardens but varied levels and boundaries. In Petts Wood and St Mary Cray we frequently work around mature planting, shared side access and existing patios. We match rooflines, cladding and glazing to complement the main property, not fight it. If you want a traditional style with timber character or a contemporary design with clean lines, we tailor it to the setting.
Our process is straightforward: consultation, design options, specification, foundations, build, then interior finishing and electrics sign-off. We offer insulation options for comfortable year-round use, plus planning advice so you know what’s realistic before work begins. Homeowners choose us for reliable scheduling, careful site management and a premium finish that lasts. You’ll also receive clear paperwork and aftercare support once the build is complete.
Across the London Borough of Bromley, gardens can sit on mixed ground and older patios, so we assess levels and drainage before setting foundations. Access and parking can be tight around High Street routes and residential roads, so we plan deliveries and waste removal to minimise disruption. We also design around boundary fences, mature trees and neighbouring sightlines common in BR5 and BR6 plots. The result is a summer house that looks right and performs well long term.




Rated 4.9/5 from over 280 verified reviews
Costs vary with size, specification and groundworks, but most Orpington projects fall into clear bands. A small, uninsulated timber summer house can start around £4,000–£7,000. A mid-sized, insulated build with electrics and better glazing is often £8,000–£15,000. Larger bespoke garden rooms with premium cladding, extensive interior finishing and more complex foundations can be £16,000–£30,000+.
Typical build time is 1–3 weeks on site once materials are ready, depending on size and complexity. A straightforward base and standard structure may take around a week, while insulated walls, electrics, plasterboard, flooring and joinery extend the schedule. Timescales can also change with access constraints, drying time for concrete foundations, and any bespoke glazing or cladding lead times. We provide a clear programme before starting.
Many summer houses fall under permitted development, especially when they’re single-storey, within height limits and used as an ancillary garden building. However, rules can change if you’re close to boundaries, on a corner plot, in a conservation area, or planning sleeping accommodation. We provide planning advice, check constraints and recommend the right route—permitted development, lawful development certificate, or a full application—before work begins.
We back our workmanship with a 10-year warranty covering structural build quality, including the main frame, roof structure and installation standards. Manufacturer warranties apply separately to items such as doors, windows, membranes and electrical components. We also document the specification so you know exactly what’s included and how to maintain it. If an issue arises, we respond promptly and arrange any remedial work in line with the warranty terms.
You can choose traditional timber styles, contemporary flat or pitched roof designs, and a wide range of cladding such as shiplap, featheredge or composite. Popular upgrades include insulation options, double glazing, rooflights, built-in storage, and full interior finishing with plasterboard and painted walls. We also design electrics around your use—desk power, heating, lighting and data points. We’ll guide you through samples and layouts to suit your budget and garden.
