Helps & Co Design Build
Premium SIP-built garden rooms, personally designed and crafted with full accountability from start to finish.
We specialise in designing and building beautifully crafted SIP garden rooms across Surrey & Hampshire, including Molesey, Esher, Woking, Kingston, Walton and surrounding areas. Every project is personally handled by Helps & Co from foundations to final finish — no subcontractors, no compromises, just premium workmanship and honest communication throughout.
Our focus is on garden rooms in Surrey that are properly insulated, structurally sound, and designed to last.

Structurally Insulated Panels (SIPs) create a warm, rigid and extremely efficient shell. Combined with careful detailing and natural finishes, you get a space that feels like part of your home – not a flimsy shed at the bottom of the garden.
Whether you need a garden office for focused work, a garden gym for staying active, or a garden studio for creative pursuits, each SIP build is tailored to how you'll actually use the space.
Thick SIP walls and roof give you excellent insulation and airtightness, making the room comfortable all year round.
Every build is tailored – from door and window positions to internal layouts, hidden storage and integrated shed space.
I'm not a big limited company. My name, reputation and workmanship go into every project – from first survey to final clean-down.
Every garden and access route is different, so all projects are quoted individually. Here's a realistic guide based on a popular 5m x 3.8m layout using a quality flat-pack SIP kit, professional labour and full finish.
£24,500 inc. VAT
Based on current SIP kit prices and a full, professionally finished build. Final price will depend on specification, access, groundworks and location.
I'll always be upfront about where cost goes. On survey we'll walk through each element together so you can choose what matters most.

How it works
Clear, simple and personal. No sales reps, no call centres – just a straightforward process from first chat to finished garden room or extension.
Send a few photos and rough sizes and I'll give you honest advice and a realistic price range – no pressure, no hard selling.
I visit in person, check access and ground conditions, then we refine the layout, finishes and electrics so the design is exactly right.
You get a clear fixed price and staged payments. I'm on site throughout and you only pay the balance once you're happy with the finished build.
Every garden room and extension is constructed using high-performance SIPs and premium materials – warm, solid and ready for year-round use. No thin cladding, no "summerhouse" tricks – just a structure that feels like a natural part of your home.

Peace of mind
Every Helps & Co garden room includes a full 10-year structural guarantee, covering the SIP structure, foundations and core build — giving you total peace of mind long after the project is finished.
SIP-based construction, solid foundations and details finished like an extension – not a thin-walled shed that only feels good in summer.
Written quote, agreed scope and sensible staged payments so you know exactly what's included and when each stage is due.
All electrics tested and certified by qualified electricians, with the right documentation for your records and future buyers.
I'm on site, not hiding behind a brand. You have my direct number from day one and you only pay the final balance when you're happy.
Based in Molesey in Surrey, I design and build SIP garden rooms, studios and extensions across Surrey, Hampshire and the Greater London borders. Most projects are within 45–60 minutes of Molesey, and for larger SIP builds I can travel further afield.
Typical garden room and extension projects in Surrey include:
For the right SIP projects I also work across parts of Hampshire and nearby counties:
I regularly work on the Surrey / Greater London border and can take on specialist SIP builds further into London where access and logistics make sense.
If you're not sure whether you're in range, just send your postcode and a couple of photos of the garden and I'll let you know.
Most SIP garden rooms range from £18,000–£38,000 depending on size, finish and glazing. For an estimate, try our cost calculator.
Many garden rooms can be built under permitted development if they meet certain height and usage rules. I'll always advise honestly and, if needed, can help you speak with the local council or a planning consultant.
Most projects are completed within 7–14 days depending on size and foundations.

A complete Helps & Co garden room usually includes the SIP shell, foundations, doors and glazing, internal lining and flooring, electrics, internal & external lighting and decoration. We'll agree the exact specification before you commit.
Yes. I regularly install high-quality flat-pack SIP kits, adapting details on site to suit your garden. This keeps quality high and speeds up the build, while still allowing for bespoke layout and finishing.
