A well-built concrete base is the difference between a structure that lasts and one that twists, settles or floods. We install bases across W4, including near Chiswick High Road and around Gunnersbury, tailored to your garden layout and intended load. Whether you’re adding a summerhouse, greenhouse or hot tub, we set out accurately and pour to the right thickness. The result is a neat slab that supports your investment and keeps doors, frames and panels aligned.
Chiswick’s Georgian houses, Victorian villas and Edwardian family homes often come with mature gardens and tight side access. We’re used to working around existing paving, planting and boundary walls, and we plan deliveries to minimise disruption. Many homeowners want discreet, high-quality finishes that complement period features rather than looking like a quick pour. Our team can also coordinate base levels with patios, paths and thresholds so everything ties together cleanly.
We start with a site visit to confirm levels, access, and what the base needs to carry. Ground preparation is done properly: excavation, compacted sub-base, formwork, reinforcement where required, then a controlled pour and tidy finish. We build in falls and drainage solutions to reduce standing water and frost damage. Fine Landscaping is trusted because we communicate clearly, keep sites orderly, and back our workmanship with a 10-year warranty.
In the concrete bases Chiswick area, we often encounter mixed ground and roots from established gardens, so we adjust excavation depth and sub-base build-up accordingly. Parking and delivery timing can be tricky near Fuller's Brewery and busier stretches of W4, so we plan pours carefully. We also consider neighbouring boundaries and party walls typical of period plots. Where needed, we’ll advise on drainage details to suit local conditions and avoid water sitting against buildings.
Rated 4.9/5 from over 280 verified reviews
Costs depend on size, thickness, access and whether reinforcement or drainage is needed. As a guide, small shed bases often start around £350–£800, while larger summerhouse or greenhouse bases are commonly £900–£2,000. Hot tub bases and reinforced slabs are usually £1,200–£3,000+ depending on load and specification. We’ll provide a clear written quote after checking levels and ground conditions.
Most bases take 1–2 days on site: day one for excavation, sub-base and formwork, and day two for the pour and finishing (sometimes same day for smaller jobs). Curing time matters too—light foot traffic is often fine after 24–48 hours, but heavy loads or building installation is best after 7 days, with full strength around 28 days. Weather and access can affect timings.
In many cases, a concrete base for a shed, summerhouse or greenhouse is permitted development, provided the structure meets height and location rules. However, restrictions can apply for listed buildings, conservation areas, or if the base changes levels significantly or affects drainage. We’ll flag likely issues during the survey and can help you check the relevant guidance for the London Borough of Hounslow before work starts.
We provide a 10-year warranty on workmanship for our concrete bases, covering issues such as poor compaction, inadequate preparation, or defects that lead to cracking or settlement beyond normal tolerance. The warranty is supported by clear specifications for sub-base, reinforcement and finish. It doesn’t cover damage caused by third-party alterations, tree root movement after installation, or overloading beyond the agreed design. We’ll explain care and loading limits upfront.
We can build standard slabs for sheds and greenhouses, thicker reinforced pads for hot tubs, and heavy-duty garage bases with steel mesh or rebar. Edge details can be square, shuttered and crisp, or formed to suit paving and path junctions. We also offer finishes from smooth trowelled to lightly brushed for slip resistance, plus drainage falls and channels where needed. We’ll recommend the best option based on your structure and garden levels.
