An in-depth look at building a garden room with a cold roof build-up

When building a garden room, you have a choice when it comes to the roof structure you choose. These Sample Plans look at the typical build-up of a well-specified garden room with a Cold Roof.

With a Cold Roof, the insulation sits between the rafters, and it requires a constant ventilation space above. These plans show you how that can be achieved.

The 3m x 3m Garden Room with Cold Roof Build-up Sample Plans Package is made up of four components:
to give you an in-depth look at designing and building a well-specified garden room.


Step by step plans offer insight into each layer of the build

We have designed a 3m x 3m garden room that is 2.5m high, meaning it is Permitted Development friendly

The Sample Plans look at the build-up of a well-specified, insulated, timber frame garden room. The 106 pages, look at each stage of the build-up.

The plans look at each layer of a Cold Roof build-up with detailed drawings.

The sample plans will give you insight into the construction of a 2.5m high garden room; even if you are planning on building a different size building, they will give you valuable insight to design it.

Frequently asked questions

You’ve got questions about the 3m x 3m Garden Room with Cold Roof Build-up Sample Plans. We’ve got answers.

Do you sell the Sample Plans separately to the Self Build Garden Room Guide eBook?

No. The Self Build Garden Room Guide eBook and any Sample Plans and Costings we produce need to be read in conjunction with each other.

Throughout the Sample Plans, we make reference to the materials you might use. The Self Build Garden Room Guide ebook explains these materials in greater detail.

The eBook also contains valuable information about Planning Permission and Building Regulations, which you should be fully aware of before contemplating building a garden room.

In short, The Self Build Garden Room Guide eBook can be read without the Sample Plans element. But, the Sample Plans and Costings need to be read in conjunction with The Self Build Garden Room Guide eBook.

Are the Sample Plans Building Control Compliant?

No. Unless you are planning to sleep in your garden room, the size of our sample garden rooms does not need to be Building Control compliant.

It wouldn't be difficult to adapt the plans to make them Building Control compliant, but advice on that is beyond the scope of our service. 

Will the Sample Plans & eBook be updated?

Yes, we will update the costings in the 3m x 3m Garden Room with Cold Roof Build-up Sample Plans from time to time. We also update the Self Build Garden Room Guide eBook as the industry adopts new techniques and materials. You will have access to the updated versions via your account dashboard.

Do you offer any deals if I buy more than one set of Sample Plans?

Yes, if you would like to compare the different roof build-up options, you might find our 3m x 3m Sample Plans Bundle useful. With this package, you get all three of our 3m x 3m Sample Plan sets looking at a cold roof build-up, a warm roof build-up and an insulated roof panel build-up.

Alternatively, our All Access Bundle will give you access to all our eBooks & Sample Plan sets.
