Prefab garage kit prices 

Our timber garage kit prices depend on what exactly you require for your new building. But as a guide, for a single, wooden garage kit with no additional features, the price starts at £2,495 plus delivery. For a large, double garage kit, ready for tiling, the price is between £4,724 and £7,366 plus delivery. 

Timber frame garages are a more affordable alternative to brick and a full oak-framed Carriage House is likely to cost two or three times as much. Plus, there is no loss of quality and they are a valuable addition to any property.

Preparation: Things you must do before you can erect your self-assembly garage kit

You’ll need a solid concrete base in place for the new building. We recommend that you talk to at least two local groundworks contractors to understand exactly what is required. 

A detailed foundation drawing will be sent out with order confirmation paperwork.  If the base is level and square the kit will go together like clockwork.

We also suggest that you independently check the base for levels and dimensional accuracy long before delivery is due should any remedial work be needed. The foundation needs to be ready at least a week before delivery of your build it yourself garage kit.

In some cases an alternative design may be necessary or it may be possible to re-use an existing foundation. If you are planning to do this, it is important to discuss this with us first.


Delivery of your timber frame garage kit 

We will deliver your garage kit to the nearest point of convenience to your foundation. The driver is likely to be on his own so please provide him with assistance to unload. If something is not clear in the itemised packing list and comprehensive erecting instructions, we are able to offer telephone assistance so don’t hesitate to call. 

If you are not erecting your timber frame garage kit immediately, then we recommend that it is stacked on bearers and covered with a tarpaulin to protect it against weather damage.

Passmores garage kits have been purchased and successfully erected by hundreds of satisfied customers across the UK.

Passmores – the trusted name in timber garages

Passmores is a trusted family business that started more than 100 years ago. In the 1950s, the demand for stables, garages and cricket pavilions took off and many of the designs we use today can be traced back to that era.

Over the years our product designs have been refined and improved and we now offer a wide range of timber frame garages and garden buildings.

All Passmore prefabricated garage kits are individually manufactured in the UK by our team of skilled staff in our workshop. Our timber mill is able to produce all our specialist requirements in-house by trained staff, under careful supervision, using modern woodworking machinery.


Sustainability and sourcing of timber 

Remember, when you choose a prefab garage kit from Passmores you are actively helping keep forests alive by opting for a building made of sustainable timber. We are part of an environmentally managed forestry scheme in Sweden that plants two new trees for every tree used. 

Forests are natural carbon sinks and producers of oxygen which means ensuring they are full and thriving has major benefits for the environment and global warming. All the wood we use in Passmores build your own garage kits comes from this sustainable scheme. 

Timber is also the only truly renewable construction material on the planet. It is becoming more popular in building construction over traditional steel and concrete because of its environmental benefits.

We’ve sold our timber garage kits to thousands of satisfied customers across the globe, including many through our partner in New Zealand. If you’re undecided and need more information, check out our Timber Garages Buying Guide here

Timber garages truly are a win-win.  Plus, they look great. But we would say that wouldn’t we?
