Case Studies


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 have 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.

The home workshop is great, more than I imagined.

The prior information, drawings and links to instructional videos were a great help, and prepared us for the task ahead . The thermowood cladding was great to work with on two sides and the box profile cladding was straight forward. The roof was just as the instructional video and went on well.

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.

The kit was fantastic!

Here are some pictures of my project I completed about 2 months ago, the kit was fantastic!

It’s such a good design!

We love the 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 am very pleased with everything

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