Marylebone homeowners expect garden buildings that feel like a natural extension of the house, not an afterthought. Whether you’re near Marylebone High Street or a quieter street towards Regent’s Park, we build garden offices, summer houses, sheds, workshops, log cabins, gazebos and pergolas with refined detailing. Our team focuses on clean lines, durable materials and practical layouts for London living. The result is a structure that adds daily function and long-term value.
The Marylebone property mix—Georgian townhouses, mansion blocks and period conversions—brings specific challenges and opportunities. Courtyard gardens, raised patios and narrow side returns often dictate how materials are moved and how foundations are formed. We’re used to working around mature planting, shared boundaries and sensitive sightlines. If you’re in W1 and want a building that complements period architecture, we’ll tailor proportions, cladding and finishes accordingly.
We start with a site visit, measured survey and a clear, itemised proposal so you can compare like-for-like. You’ll receive practical guidance on insulation, electrics, ventilation and security—especially important for garden rooms and offices used year-round. Our builds are managed end-to-end, with tidy working practices and respectful neighbour considerations. Fine Landscaping is trusted because we communicate clearly, keep schedules realistic, and stand behind our workmanship.
As garden building contractors in City of Westminster, we plan carefully for restricted access, controlled parking and tight delivery windows around Baker Street and nearby streets. Many gardens sit behind mansion blocks or period conversions, so we assess routes, storage space and neighbour boundaries before work begins. Ground conditions can vary between paved courtyards and softer planting areas, which affects base preparation and drainage. We also help you navigate any local constraints that may apply to your plot and proposed structure.

Costs vary by size, specification and access. As a guide, a quality shed or small workshop often starts from £2,500–£6,000 installed. Insulated garden offices and garden rooms typically range from £12,000–£35,000+, depending on glazing, electrics, heating and finishes. Larger log cabins or fully fitted multi-room buildings can be £30,000–£70,000+. We provide an itemised estimate after a site visit in W1.
A simple pergola or gazebo can often be completed in 1–3 days. Sheds and summer houses usually take around 3–7 days depending on base works and assembly. Insulated garden rooms and offices commonly take 2–6 weeks from start on site, especially where electrics, plastering, flooring and bespoke joinery are included. Timescales depend on access, weather, ground preparation and any made-to-order materials.
Many garden buildings can fall under permitted development, but rules depend on height, footprint, placement, and whether the property is listed or in a conservation area—both common around Marylebone. Outbuildings used as living accommodation can also change requirements. We’ll discuss intended use, measure the site and flag likely constraints early. If needed, we can help you gather drawings and information to support a planning application or lawful development check.
We provide a 10-year warranty on our workmanship for garden buildings we design and install, covering structural assembly, fixings and installation-related defects. Manufacturer warranties apply separately for items such as roofing membranes, doors, windows and cladding systems, and we’ll pass these on in writing. We also advise on maintenance to keep timber, finishes and seals performing well in London conditions. Any snagging is handled promptly and professionally.
We offer a wide range of options to suit Marylebone gardens and period architecture: cedar or composite cladding, painted timber, contemporary aluminium glazing, and traditional framed doors. Roofing choices include EPDM, felt systems and pitched tiled or slate-style finishes. Interiors can be basic storage or fully insulated with plasterboard, lighting, sockets and engineered timber or LVT flooring. We’ll guide you through layouts, sightlines and finishes to match your home and budget.
