What is genuinely customisable — and what is not
Customisable: width, length, leg height, roof style, panel gauge, colour and two-tone wainscot, number and position of roll-up doors, personnel doors and windows, lean-to additions, and whether it is open, partially enclosed or fully closed. Not customisable in any useful sense: the fundamental frame geometry and the panel profile. Anyone offering unlimited customisation on a pre-engineered system is overselling.
Where custom saves money and where it costs
Custom length is nearly free — buildings are built in five-foot increments and the frame simply repeats. Custom width is expensive, because clear-span framing has to carry more load. Custom leg height sits in between. Extra openings each cost material plus labour. So the cheapest way to get a custom building is to be flexible on width, generous on length, and deliberate about how many doors you actually need.
Design it in 3D, then let us check it
Our 3D designer lets you configure size, colours, doors and windows and see it before you commit. Do that first — it is genuinely useful for getting the layout in your head. Then talk to us, because the configurator will happily let you specify a building that fights your site, your county's wind rating, or the way you will actually use the floor. That conversation is free and it is where most orders get improved.
