A garden annexe turns underused outdoor space into a fully self-contained retreat for work, guests, or multigenerational living. In W2, we create annexes that sit comfortably behind period homes and mansion blocks, with thoughtful layouts and high-end finishes. Whether you’re near Queensway or a short walk from Hyde Park, we’ll design around your garden’s proportions and privacy. Expect a complete build: bedroom space, bathroom, and a practical kitchenette.
Bayswater’s stucco townhouses, mansion conversions, and period flats often come with compact gardens, shared boundaries, and strict aesthetic expectations. We’re experienced in creating garden annexes Bayswater area homeowners can use year-round, with proper insulation and ventilation to avoid condensation. Access can be tight through side returns and communal hallways, so we plan deliveries and lifting carefully. The result is a calm, efficient space that feels like a natural extension of your property.
Fine Landscaping manages the project end to end, from measured survey and concept design to electrics, plumbing, and final fit-out. You’ll get clear specifications, staged payments, and a tidy site routine that respects neighbours and building managers. We also provide planning support and coordinate documentation where required. Many clients choose us for garden annexes in City of Westminster because we’re methodical, responsive, and consistent on quality.
Bayswater gardens often sit behind period façades, with mature trees, party walls, and limited access for materials. We plan logistics around controlled parking, delivery windows, and considerate noise management. Ground conditions can vary, so we assess drainage and foundations early to avoid surprises. Where properties are managed or leasehold, we help with practical details that keep approvals and neighbours onside.
Rated 4.9/5 from over 280 verified reviews
In Bayswater, a typical self-contained garden annexe with insulation, electrics and plumbing often starts around £55,000–£85,000 for a compact studio-style build. Larger annexes with a separate bedroom, higher-spec bathroom, premium glazing, or bespoke joinery commonly range from £90,000–£140,000+. Costs depend on access, foundations, services runs, and the level of interior finish you choose.
Most garden annexes take around 8–14 weeks on site once designs, specifications and start dates are agreed. Simpler, smaller footprints can be quicker, while complex groundworks, long plumbing runs, or high-end interiors can extend timelines. Lead times for glazing, kitchens and bathrooms also matter. If planning or party wall matters apply leading up to the build, allow additional time before work begins.
Some garden buildings can be permitted development, but a self-contained annexe with a bathroom and kitchenette can trigger additional planning considerations in the City of Westminster. Restrictions may also apply for listed buildings, conservation areas, and properties near key streetscapes. We review your site, intended use, height and boundary distances, then advise the safest route. Where needed, we support drawings and submissions to reduce delays.
We provide a 10-year warranty covering workmanship and key structural elements of the garden annexe build. This includes the integrity of the build envelope, installed components we supply, and the standard of our construction. Manufacturer warranties also apply to items such as windows, doors, insulation products, and sanitaryware where relevant. We document what’s covered and provide aftercare guidance to keep everything performing well.
You can choose from contemporary or more traditional looks to suit Bayswater’s period setting—timber cladding, brick slips, or rendered finishes are popular. Inside, we can specify compact kitchenettes, walk-in showers, built-in storage, and acoustic upgrades for home working. Options include underfloor heating, skylights, and large sliding doors for light. We guide you through finishes and layouts that balance budget, durability, and privacy.
