As one of the UK’s leading manufacturers of garden offices and garden rooms for over 15 years, Future SIPs, The Garden Room Superstore, has used its experience to manufacture DIY garden room kits for gardens of every size and style. Our kits use SIPs manufactured in our own workshops, making them straightforward to order and quick to install.

We have eight modern and versatile Premier models to choose from, with selected designs also available in the Classic range. You can also choose how much or how little of the kit you want us to supply.

Self-Build Garden Room Kits to Suit Your Budget

We offer two ranges: Premier and Classic. Premier offers the widest choice of models, sizes and upgrade options, while Classic is a fixed off-the-shelf range available in selected models and sizes. Both ranges use insulated SIP wall and floor panels, with PIR-insulated composite roofs now used on future orders.

Our flat-pack kits are delivered directly to your home, with short lead times, ensuring that you don’t have to wait months to enjoy your garden room. To spread the cost, we offer finance options.

With a beautifully designed garden office pod or garden room, you can enhance your home while adding space and value.

DIY Garden Room Kit Types

We offer two specification ranges: Premier and Classic, with kits available across three build stages: Shell, Shell & External and Complete Kits.

Our Premier range offers the widest choice of models, finishes and upgrade options. Premier kits use 122 mm SIP wall and floor panels with 100 mm insulation, plus a PIR-insulated composite roof. Most models use an 80 mm composite roof, with a 100 mm composite roof used on sizes 4.0 m depth and above.

Our Classic range is a fixed off-the-shelf option, available on Studio, Executive, Haven and Metro models only. Classic kits are available in eight sizes: 3 m x 2.5 m, 3 m x 3 m, 3.5m x 2.5 m, 3.5 m x 3 m, 4m × 2.5 m, 4m x 3 m, 4.5 m x 3 m and 5m x 3 m. Classic kits include 75 mm insulation to the walls and floor, an 80 mm PIR-insulated composite roof, pre-adhered MDF wall finish and an exposed composite roof finish internally. Bespoke options are not available on the Classic range.

The composite roof system is lighter than a SIP roof, while still offering strong insulation performance.

FAQs

Yes, we can adapt any of our Premier rooms or create a bespoke kit to your size and specification, which we will provide a price for.

We provide a comprehensive installation guide with every room.

You will need to consider the type of base that your self-build garden room kit will be constructed on. Typically, we would expect you to need one of three types of foundation: pad, ground screws existing/new concrete base. You can use adjustable feet to level off the base. Please discuss with us the type of base you are considering as we progress your order.

The kit you have ordered will include the elements that are applicable to that kit and the SIP panels will be cut to size, ready for installation. Kits are delivered to the kerbside at the property.

Most rooms will not require planning permission and will fall under Permitted Development rights. However, if you are unsure, please seek guidance from your Local Planning Authority. All planning permission requirements are the responsibility of the Householder.

Thermowood, British Cedar and Western Red Cedar will all weather over time but do not require treatment. Composite cladding is maintenance free.

Premier Kits can be modified with additional/alternate-sized windows and doors and aluminium glazing if required. Prices will be quoted accordingly.

It takes 6–8 weeks from confirmation of your order and is subject to our production schedule.

Self-Build Garden Room Case Studies

Reviews

Thanks once again for your support when we were buying/building the garden room.

We are using the space all the time now, as we are having major work done on our house, so the garden room is being used as a study, living room and yoga studio – sometimes at the same time! With a perfect view out over the lagoon through the large window at the end, it is proving to be a sanctuary away from the madness of the building work. Wishing you all the best, and thanks once again for your support when we were buying/building the garden room.

I couldn’t be happier. Top quality product, top quality service. Great end-to-end experience.

I was worried about my garden office project. I know nothing about DIY, it was a very challenging site, and I wanted lots of customisations on the building itself. I really needed a partner, not just a supplier. The team at Future SIPs were fantastic, and gave me expert guidance all the way through the process. They were all very friendly and patient when I had questions. Even the driver who delivered the kit took the time to talk me through all the elements and helped me to get it stored away properly prior to the build. The contractor that built it for me was full of praise for the quality of the kit, and said the precision of the SIPs, cladding etc made his job much easier. I’d recommend Future SIPs in a heartbeat.

Really, really pleased with it

Really pleased with it all and enjoy sitting and taking in the view, glass of wine in hand of course! We did new decking immediately outside of it, in order to open the bi fold doors fully as an extension to the room. All in all, really, really pleased with it.

Such excellent service!

My wife and I just wanted to thank Richard, yourself and the rest of the team for all the support, ad hoc technical tips and advice that we got whilst building our Garden Room. I know that I visited the show room 2 or 3 times and Richard and the team, even though quite busy, showed us every courtesy and help. Such excellent service! I have finally completed the build of our 3 x 5m Garden Room, and we are very pleased with it.

It’s such a good design!

We love the garden room and it was so easy to build. It’s such a good design!

It’s perfect and we love it!

We use it as a gym and use it most days, it’s perfect and we love it!

Great customer service and I’ll definitely be using you guys again.

Just wanted to email to thank you and your team. Great customer service and I’ll definitely be using you guys again. The driver was a really nice guy and very helpful. The build went really well and the customer was very happy.

I have completed the build of my DIY room that I purchased from you and I am very pleased with everything, looks really good.
