Coulsdon’s semi-rural setting makes extra space at home especially valuable, whether you’re near Farthing Downs or down by Old Coulsdon. Our garden rooms are purpose-built, fully insulated and tailored to how you’ll use them—work, hobbies, training or hosting. We design around your plot, outlook and access so the new space feels like a natural extension of your home. Expect clean lines, smart storage options and durable external finishes suited to UK weather.
We regularly work with large detached houses, well-proportioned 1930s homes and newer developments across CR5, including Chipstead Valley and Hooley. Each property type brings different constraints—side access widths, existing patios, mature planting and boundary levels. We plan the footprint and orientation carefully to protect light into the house and make the room comfortable all day. The result is a space that adds practical square footage and supports how your household actually lives.
From the first survey to final handover, we keep the process straightforward: design, specification, groundwork, build, electrics and finishing. You’ll get clear scope, realistic timescales and tidy site management, with updates at each stage. We use proven construction methods for insulation, ventilation and moisture control to keep the room warm in winter and cool in summer. Local homeowners choose us for consistent workmanship, transparent communication and a finish that lasts.
Projects in the garden rooms Coulsdon area often involve sloping plots and varied ground conditions near downland edges such as Happy Valley. We assess levels, drainage and base construction so floors stay stable and dry. Access and parking can be tight on some residential roads, so we plan deliveries and waste removal to minimise disruption. For garden rooms in London Borough of Croydon, we also check any planning constraints and boundary considerations before work begins.
Rated 4.9/5 from over 280 verified reviews
Most garden rooms in Coulsdon fall between £10,000 and £40,000, with many homeowners choosing a specification in the £15,000–£25,000 range. Costs depend on size, insulation level, glazing, cladding type, internal finishes, and electrics (including heating and data). Ground conditions, access for materials, and any extra groundwork or drainage can also affect the overall budget.
A typical build takes 2–4 weeks from the start of onsite works, depending on the design and specification. Groundworks and the base are usually first, followed by the structure, insulation, doors/windows, electrics and interior finishing. Timescales can extend if access is restricted, the site is sloped, or you choose bespoke joinery, larger glazing, or higher-end finishes that require longer lead times.
Many garden rooms can be built under permitted development, but it depends on factors such as height, position near boundaries, total garden coverage, and whether the property has restrictions. Some homes may have conditions on previous permissions, or be affected by local planning considerations. We review your site and proposed design, then advise what’s likely to apply in the London Borough of Croydon and help you take the right next step.
We provide a 10-year warranty covering workmanship and key construction elements, giving you confidence that the structure is built to last. This includes the integrity of the build, the base and core assembly, and defects arising from installation. Manufacturer warranties also apply to specific components such as doors, windows, cladding products and electrical items. We’ll explain what’s covered and provide documentation at handover.
You can tailor the design to your home and garden, from contemporary studios to warmer summer-house styles. Popular options include composite or timber cladding, aluminium or uPVC glazing, rooflights, and different insulation and heating setups for year-round comfort. Internally, choices range from plastered walls to feature panelling, plus fitted storage and acoustic upgrades for offices or music rooms. We’ll guide you through options to match your budget and how you’ll use the space.
