Based in Surrey and serving Bromley, South East London, and Kent, M Withall Landscapes brings landscaping expertise and construction quality together under one team, from foundations and groundworks through to electrics, flooring, glazing, and cladding.
We build garden rooms across Bromley to suit a wide range of uses. Every structure is bespoke, designed around your garden space and built to the specification you choose.
A garden office gives you a dedicated, professional workspace just steps from your back door, completely separate from the distractions of the main house. Our garden office buildings are fully insulated for year-round use, with electrics, data cabling, and internal finishes all planned and installed as part of the build. A well-designed garden office in Bromley can transform how you work from home and with more homeowners working flexibly than ever, it is one of the most practical investments you can make in your property.
A garden studio creates a private, dedicated space for creative work, whether you need a painting and art studio, a music room, a photography studio, or simply a quiet retreat away from the house. Our Bromley garden studios are built to your exact requirements, with glazing, interior finishes, flooring, and cladding all chosen to match your vision. Garden studios can be designed to feel contemporary and light-filled, or warm and characterful; the choice is yours.
A garden gym gives you a private training space at home, available whenever you need it. We build garden gym structures at a range of sizes to suit your garden space. A popular option is a 5.2m x 4m build, which provides enough room for a full range of equipment. High-grade insulation ensures the gym remains comfortable to use through winter and summer alike, and we can incorporate rubber flooring, wall-mounted storage, and specialist electrical points as part of the fit-out.
Bromley garden rooms do not have to be purely functional. Many of our clients choose to build a garden bar, a cinema room, or an entertainment space that extends their home’s social areas into the garden. These builds follow the same construction quality as our offices and studios, hand-built, fully insulated, and finished to a high standard.
For homeowners who need more versatile space, we also build garden annexes and larger multi-purpose garden rooms that can serve multiple functions. These larger garden buildings are ideal for families who need flexible space that can adapt as their lifestyle changes.
Garden room installation requires more than placing a structure in the garden. Ground preparation, drainage, and foundations protect long term performance. Professional landscaping experience ensures each garden room sits correctly within the wider garden layout.
Insulated garden rooms use modern construction methods and materials to support year round comfort. Walls, floors, and roofs receive proper insulation to maintain temperature through winter and summer. Timber cladding, modern finishes, and glazing options combine durability with appearance. Professional installation protects structure, finish, and lifespan while reducing future maintenance.
Every garden room we build in Bromley is constructed from scratch on site by our experienced carpenters, not assembled from flat-pack components. This approach gives us complete control over quality, specification, and fit, and means every structure is designed to integrate properly with your garden space rather than simply sit in it.
Our construction process covers every stage of the build:
Most Bromley garden room builds are completed within 3 to 6 weeks from the start of construction, depending on size and specification. We provide a clear schedule at the outset so you know exactly what to expect and when.
This is one of the most common questions we receive from homeowners considering a garden room in Bromley, and, in most cases, the answer is no.
Most garden rooms in Bromley fall under Permitted Development rights, meaning they can be built without a formal planning application, provided they meet the following conditions:
Additional restrictions apply if your property is in a conservation area, a listed building, or within a designated Area of Outstanding Natural Beauty. In these cases, permitted development rights may be more limited, and a planning application may be required. We recommend consulting your local council or a planning specialist for guidance specific to your property.
The 2.5m rule is particularly important to understand. Any garden room, including those built close to the boundary of a property, must remain under 2.5 metres at the eaves to fall within permitted development. Buildings exceeding this height require planning permission, regardless of other factors.
Garden room cost in Bromley varies depending on the size, specification, and internal fit-out you choose. As a guide, garden rooms in Bromley typically range from £15,000 to £50,000, with most residential projects falling between £18,000 and £35,000.
To give a clearer sense of pricing by size:
These figures include foundations, structure, insulation, cladding, glazing, and electrics. Internal flooring, painted finishes, bespoke joinery, and additional features such as specialist gym flooring or fitted furniture are costed separately depending on your specification.

Most garden rooms fall under Permitted Development rights and do not require planning permission, provided they meet the standard conditions: single storey, under 2.5m tall, covering no more than 50 per cent of the garden, and used for personal purposes. Additional rules apply in conservation areas. We can advise during your free site survey.
Most garden room builds in Bromley are completed within 3 to 6 weeks from the start of construction. We provide a clear build schedule at the start of every project so you know exactly what to expect.
Occasional overnight use is common, but garden rooms built under permitted development rules must not be used as permanent sleeping accommodation or as a separate dwelling. If you intend to use the space regularly as a guest room or annexe, we recommend seeking planning advice before proceeding.
The 2.5m rule refers to the maximum eaves height permitted for garden rooms built under permitted development. Any garden room, including those positioned near the boundary, must not exceed 2.5 metres at the eaves. Buildings taller than this require a formal planning application.
