Classic Haven DIY Garden Room Kit

The Classic Haven is exactly that – a little self-build Haven for your garden.

This angular design offers a striking visual in your garden with a diagonal overhang giving a real sense of design. A single opening door with glazed panels to either side make the front elevation sleek and clean, allowing plenty of light into the room.

Cladding Options

Our Shell & External and Complete Kits give you the choice of external cladding for your garden room kit. There are 3 choices: Thermowood, British Cedar and Western Red Cedar. Prices are shown for each option on our kit models pages and assume all four walls of the building are clad in one timber type.

You can vary whether all sides of your room are clad in the same timber; where external walls are not visible you may prefer to opt for the cheaper timber and we can provide a price change for this on request.

Glazing Options

Shell & External and Complete Kits: 2400mm of glazing with a single opening door and glazed panels either side.

Reviews

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.
