I started Heritage Garden Studios because too much of this industry focuses on selling units, not delivering outcomes. The building arrives, the team leaves, and the client is left to figure out the rest.
That’s not how a £50,000 investment should work.
We approach garden rooms the same way we approach building a home. Residential-grade SIPs construction. Genuine thermal performance. Properly specified electrics and plumbing. And a dedicated team that stays with your project from initial design through to final handover.
We’re also honest about what shouldn’t be built.
If a garden room won’t deliver what you actually need, we’ll tell you. If a full SIPs extension is the better solution, we’ll guide you in that direction. You’re making a significant investment—you deserve clear, straightforward advice.
PS. Our work has been recognised with multiple industry awards, including the Doncaster Business Award 2025, Houzz Pro Service Award 2025, and Compare Garden Rooms – Best Garden Room 2025 Award.
Every Heritage garden studio starts with one of five designs. Each is a proper architectural response to a different way of using the space, not a cosmetic variation. Once you’ve picked the design, the rest is yours: size, cladding, glazing, doors, interior. Nothing gets built until the spec is right.
Every model is available in over 150 size configurations. Cladding options include larch, cedar, thermowood, and composite. Doors include patio, bi-fold, sliding, New Wave, and Crittall-style heritage doors. If you want something different, say. We design around the brief, not the catalogue.
From £25,000 garden rooms to high-spec buildings designed for long-term use, every Heritage Garden Studio is constructed using SIPs panels — the same system we use for annexes and extensions.
Most garden studio projects fall between £28,000 and £75,000, depending on size, specification, and use.
We’ll give you a realistic price range before anything is designed. We don’t just sell buildings. We help you decide what’s worth building — and what isn’t.
Specification
A garden room might look similar on day one — but how it performs over time comes down to how it’s built.
We use Structural Insulated Panels (SIPs), the same system used in our annexes and extensions, to deliver real insulation, strength, and long-term performance.
Every Heritage garden studio is specified as a permanent, year-round building — not a lightweight seasonal room.
From the SIPs structure to the glazing, electrics, plasterboard finish and external cladding, the important details are built in from the start.
| Wall & Floor construction | 97mm Structural Insulated Panels |
|---|---|
| Roof construction | 123mm Structural Insulated Panels |
| Insulation | Integrated within the SIPs system for year-round use |
| Glazing | Double-glazed units with Pilkington K Glass™ as standard |
| Electrics | Professionally installed an compliant with BS 7671 |
| Internal finish | Plasterboarded, skimmed and decorated finish |
| External finish | Choice of timber and composite cladding options |
| Doors & glazing | Sliding, bi-fold, heritage-style and patio door options |
Specification isn’t an upgrade — it’s the foundation of how the building performs.
Our process
A well-built garden room starts long before we arrive on site. We take you through a structured process so the design, specification, costs and timescales are clear before the build begins.
We start with a conversation about how you want to use the space, your site, your timescale and what you want the building to achieve.
We look at access, groundworks, planning position, services and budget so you understand what is realistic before we move into design.
Your building is designed around your brief, including size, layout, glazing, cladding, internal finish and specification.
Materials are scheduled, key details are confirmed, and your project timeline is planned before work starts on site.
Groundworks, SIPs construction, glazing, electrics, plastering, finishing and handover are managed through one coordinated process.

Download the guideBefore you build
Most of our clients have already spoken to other suppliers before they come to us. These are the questions that tend to matter most when making a decision.
It depends how it’s used. A well-built garden room used daily for work, training or living space delivers long-term value. A poorly specified one rarely does.
It may not add a direct like-for-like increase in value, but it can improve appeal, usability, and saleability — particularly for buyers looking for flexible space.
Many garden rooms fall under permitted development, but not all. Height, position and site constraints all matter — we guide you through this early.
Structure, insulation, specification, and who actually builds it. Not all garden rooms are built to the same standard — even if they look similar.
If you need connected living space, an extension often makes more sense. If you want separation, speed and flexibility — a garden room usually wins.
Choosing an experienced, structured team reduces risk significantly. And if anything does need attention, you want a company that’s still there to support you.
THE OLDHAM-ROBERTS FAMILY
What more can we say? ABSOLUTELY FANTASTIC!
Heritage Garden Studios built our granny annexe late last year, and we couldn’t be happier. It’s a perfect, cozy home for my elderly mother, and she loves it! Sarah and her team went above and beyond, even with our constant changes.
They also landscaped our garden, and thanks to Richard’s expertise, we now have a stunning outdoor space and a lovely view from our kitchen window.
Thank you, Sarah, Simon, and Richard!”
THE ELLIS FAMILY
The experience from start to finish of our garden room build has been absolutely fantastic! Sarah and her team worked tirelessly, even during storms, to complete it in time for our family Christmas. We’ve never seen a team work so hard, even around other work going on in the house. We’re so grateful—they made our Christmas! This won’t be the only project we’d like them to do, and we highly recommend Heritage Garden Studios
THE ROTHERY FAMILY
Our plans for a garden room in 2025 changed when we met Sarah at the Yorkshire Show in 2023. We always dreamed of a space to enjoy the garden year-round, and Heritage Garden Studios delivered far more than we imagined.
Despite the challenging topography of our garden, the team designed a bespoke room with a wrap-around deck, glass balustrade, and storage underneath. The attention to detail and expertise from Sarah and her team were unmatched.
Friends thought we were building a glorified shed but were amazed by the result. We love our garden room and use it in all weather. Thank you, Sarah and team—we highly recommend Heritage Garden Studios!”
THE WALKER FAMILY
We couldn’t be happier with our new SIPs home extension from Heritage Garden Studios! The team was incredible, ensuring every detail was perfect and making the process seamless.
Replacing our old conservatory with a stylish SIPs extension exceeded our expectations. The high-quality materials, like aluminium windows and composite cladding, make it energy-efficient and durable year-round.
Sarah, Richard, Simon, and the team were professional, and friendly, and kept us informed throughout. Our home has been completely transformed—we highly recommend Heritage Garden Studios!”
THE BONNER FAMILY
Sarah and the team made everything simple from the start of the project, they completed works when they said they would and to a very high standard and went above and beyond to be helpful in anyway they could. The quality of the build and finish is exceptional and the after sales service is easy to request and they are only to happy to help.
THE PALMER FAMILY
’We are so pleased with our new SIPS garden annexe—it’s far better than standard! Sarah worked closely with us to design and build a stunning, high-quality annexe that exceeded our expectations. Despite challenges with our tricky plot, the team handled everything brilliantly.
If you’re looking for a bespoke garden annexe in Yorkshire, you can’t do better than Heritage Garden Studios. We’d be proud to show off the results—it’s absolutely stunning!’
THE TEASDALE FAMILY
We wanted a flexible indoor/outdoor space for quiet time or entertaining and chose Heritage Garden Studios for their personal touch and understanding of our vision.
Sarah and her team guided us through the design, offering expert advice on lighting, flooring, and heating. Their attention to detail exceeded our expectations, and the end result is amazing.
We highly recommend this family-friendly business!”
THE COWLING FAMILY
Sarah & her team have been fantastic from start to finish. We honestly couldn’t be happier with both the quality of work carried out and the service that was offered to us by Heritage. We had a Garden Office installed using the Slatted cladding effect & what a transformation it has made to our garden. We absolutely love it, we couldn’t recommend Sarah enough.
THE WILLIAMS FAMILY
Excellent Service and a Great Quality Product
This was a great experience from start to finish, from great design help to final touches in creating our garden gym/studio. The team was efficient and unobtrusive, started on time and finished ahead of schedule but mostly we were just delighted with our new purpose-built space. Huge thanks to Sarah and the team.
THE HALLAM FAMILY
We looked at many garden room providers and Heritage really stood out to us. They clearly care deeply about what they do and this has come across in every interaction. The design process was simple and intuitive and Sarah was constantly on hand with such useful pearls of wisdom. The installation was incredibly smooth; we had a skilled and professional team. This building has become a central part of our home, we use and love it every day!
THE MELLOR FAMILY
I can only say this has been a very smooth journey with a fabulous team of Sarah, Simon,Richard and Paul. From the point of meeting the team, to get assistance on our design for my mums garden room, nothing has been too much trouble. The quality of the product and workmanship is amazing. I can fully recommend you use this family business as we research some of the bigger companies and nothing compared. Now just waiting for it to dry out and get it painted. Thanks you all
THE WELLS FAMILY
I couldn’t believe my build took only two weeks, and the result is fantastic. I can’t fault the friendly team, who were extremely tidy.
I have artificial grass, and they vacuumed it each evening. They were here from dawn until after dusk each day. I can’t recommend them enough.
