Not everyone wants technical data for their building, but for those that do, you should be able to find further information here.

Building Sizes

External, internal, clear dimensions for each building.


In order to ascertain whether you need Building Regulation Approval, amongst other things, you will need to see if your building is over the internal floor area allowed under the regulations.

The other items you may need to take into account will be found on the government website, Planning Portal. Please note the planning portal only covers England and Wales. If you live in Scotland you will need to contact your Local Authority.

Below you can download a list of the internal areas depending on the size of your building.

Computer Aided Drawings (CAD)

Our CAD drawing service is available to anyone who needs to submit drawings for Local Authority Approval.

Below are is an example of the type of drawing we will provide. We will provide a similar drawing but for your specific project, simply tick the box on your order form. Drawings requested after a building is ordered are usually supplied free of charge. Drawings requested prior to an order being placed may be chargeable.

Base Design

Sectional concrete garages and buildings are very heavy. As a result, all of our buildings require a concrete base. Unfortunately we cannot build on block paving, flagstone paving or tarmac. If you are unsure about the location of your garage/building, your local Lidget Compton agent will be able to help. In many cases they will also be able to provide you with a free site survey so you can find out exactly what you need and perhaps more importantly, what will fit!

Concrete garage bases should be perfectly flat, square and level. The picture below shows the preparation for a good solid base.

Ideally your concrete garage base should be 6″ (150mm) wider and 6″ (150mm) longer than the external dimensions of your building. It should also be chamfered slightly around the edges, this is to allow any rain or water to run away from the garage and off the base. This will help to prevent any water ingress underneath the garage panels.

Below you can see a concrete garage base being finished (or floated) off.

The design of the base should be suitable to the local soil conditions. While your agent can give you advice on most aspects of your concrete garage purchase they not be able to advise you on this. However, normally they can provide the service of refurbishing your existing base or putting in a new base.

Garage Planning Permission

The rules regarding Planning Permission are reasonably simple, but the interpretation of them does vary from authority to authority.

Visit the government’s Planning Portal, where you will be able to see what is required.
