With land prices often coming at a premium it is important to maximise the space inside the building to ensure you get the best bang for your buck. Often people are finding that sites in desirable locations such as arterial routes, distribution hubs and the region you service may be a smaller size than if you were to seek a location farther away with more land. A compromise between location and size, however, doesn’t mean a compromise on the usable square meters of the building itself.
The first way to make sure that the internal space is fully maximised is by ensuring that the structure itself has been optimised to maximise the internal clearances. Too often bulky portal frames, purlin and girts are used to create large spans. In extreme cases reinforcing braces are required, which may impact things like racking space. Partnering with a firm that has engineered their portal frames, purlin and girts to be as strong as possible, while being designed to optimise space, can reward your business or tenants with a more efficient internal volume and a greater return on their investment.
In this next section, we’ll explore the different aspects of a commercial warehouse or manufacturing facility’s constructions and identify optimisations to look for.
The best way to optimise space is to have a clearspan portal frame design. Internal props or columns may seem like a way to save some money, but they can quickly become a false economy.
Props midway inside the building can often create the following inefficiencies in the internal space of any building:
The depth of the portal frames is also a consideration – typically the building dimensions are taken externally which means that the internal clearances are less. Because of this it is important to ensure that the portals are designed to maximise the internal space. Things like corner knee braces and deep lattice rafters can reduce the internal space more than people realise.
Purlins and girts between the portal frames can give another 200-350mm of internal space and while it’s possible to arrange racking, forklift lanes, compressor lines and overhead crane layouts around these, that will place constraints on your building layout and may lead to additional costs later down the track. It’s better to have a building designed with minimal internal encroachments from the beginning to increase long-term layout flexibility and reduce the costs of any future changes.
There are also other extra design elements that can help maximise the internal space beyond the portal frames:
Canopies provide advantages like:
Cantilever canopies also have the advantage of not impending yard space or turning areas, while giving extra covered area.
Mezzanine floors can be a great use of space as they maximise often unused roof area. They are particularly good for extra office spaces as an upstairs work environment can also come with a nice elevated view.
If you, or your planned tenant, can foresee a lot of low-height work where the space above will be under-utilised then a mezzanine is an excellent solution. Storage, showrooms or reception areas can be classic applications for low-height ground-level space whereby offices above are a natural fit.
However, a large mezzanine may not be a cheap way to get extra space as sometimes they do require a lot of extra steel support and can change fire rating requirements. It’s worth talking to the team at XL early in your planning process to understand the additional requirements for a mezzanine.

The team has extensive experience factoring a multitude of considerations into a build. Our in-house design team makes reworking designs a breeze, which is perfect if you have multiple stakeholders with input on how the building needs to be designed.
