Coupled with the increasing popularity of the 4WD leisure vehicle comes a demand for increased size and height of replacement concrete sectional garages.
Typically a prefabricated building is 6ft6in (1.98m) to eaves which provides actual under-door clearances in the region of 6ft1in (1.8m). For example this height is equal to that of a Land Rover Discover and a Classic Range Rover and that's before your consider the roof rack and aerial!
Most manufacturers of concrete sectional buildings offer an increased eaves and door clearance; some can achieve greater clearance simply by exchanging the main door for vertical-lift 'shutter' type operation. There is a common misconception that roof style will affect actual internal clearance, this simply is not true.
We recommend an eaves height no less that 7ft6in (2.29m) as other factors such as the slope towards your garage may reduce your actual clearance as well as a weather-bar situated behind the door. Only a few manufacturers can offer 7ft6in panel height as the technology behind fabricating such a tall panel escapes some brands.
For commercial applications such as required for minibuses, lorries and forklift truck comes a completely different breed of industrial and commercial prefabricated building which uses the same concrete panels to eaves but achieves greated height through steel cladding to the desired height.
It is worthwhile to note that even at 2.29m to eaves this building is still below one of the planning thresholds which places a restriction at 3.0m to eaves and 4.0m to ridge height.
