A shed is only as good as the base beneath it, especially in W1 where gardens can be compact and access is often restricted. We install bases that prevent sinking, rocking doors and damp floors, whether you’re near Marylebone High Street or closer to Regent’s Park. Every base is set out accurately to suit your shed footprint and door clearance. The result is a clean, level platform ready for installation.
Homeowners across Marylebone often have Georgian townhouses, mansion blocks and period conversions with courtyards, side returns or roof terraces. These spaces can include older paving, mixed sub-bases and uneven falls that need careful correction. Our shed bases Marylebone area service is designed for tidy, low-disruption work with a premium finish. We also plan for storage access, drainage routes and neighbouring boundaries typical of City of Westminster properties.
We start with a site visit to measure, check levels and confirm the best base type for your shed and ground conditions. Preparation includes excavation where needed, compacted sub-base, edging control and drainage considerations so water doesn’t sit under the structure. You’ll get clear options, a written scope, and workmanship backed by our warranty. Many clients choose us for reliable scheduling, neat working practices and consistent results—even when access is via narrow passages or shared entrances.
Marylebone sites often involve tight access, controlled parking and considerate working hours, especially around Baker Street and busy residential streets. We plan deliveries, waste removal and on-site mixing to suit local constraints. Ground build-ups can vary between older patios and made ground, so we assess stability and specify the right sub-base depth. Our shed bases in City of Westminster are installed with clean edges and sensible falls to manage runoff.

Costs depend on size, base type, access and how much excavation is required. As a guide, small paving slab bases often start around £450–£900, while concrete bases commonly fall between £900–£2,000+. Plastic grid bases can be £600–£1,500 depending on fill and edging, and timber bases typically £700–£1,800. Courtyard access, stairs and parking restrictions in W1 can increase labour and handling time.
Most shed bases are completed in 1 day for smaller sizes and straightforward access. Larger bases or those needing significant excavation, retaining edges or drainage tweaks may take 2–3 days. Concrete bases may require additional curing time before the shed is installed, depending on thickness and weather. Timescales are also affected by narrow access routes, manual barrowing distances, and whether we’re removing old slabs or existing structures first.
In many cases, a shed base is permitted development as part of normal garden works, provided the shed and its location meet the usual limits. However, City of Westminster rules can be stricter for listed buildings, conservation areas, and properties with specific lease or estate requirements. We’ll flag any potential issues during the survey and advise if you should check with the council or freeholder. We also design falls and drainage to avoid runoff problems.
We provide a 10-year workmanship warranty on shed base installations, covering issues such as settlement caused by inadequate preparation, poor compaction, or incorrect levels. It also covers defects in our installation of edging and base construction where applicable. The warranty doesn’t cover damage from third-party alterations, tree root movement beyond reasonable control, or extreme events such as flooding. We’ll explain care guidance and recommended shed fixing methods to help your base perform long-term.
We install concrete bases for maximum rigidity, paving slab bases for a clean modular finish, plastic grid bases for permeable support, and timber bases where a raised, ventilated platform suits the site. We can add edging restraints, adjust levels for door thresholds, and incorporate drainage falls to keep water away. During the survey, we’ll recommend the best option based on shed size, intended use (storage or workshop), and your garden’s existing surfaces and access.
