Measure your workbench, tools, door opening and working clearances before choosing a flat-pack timber workshop shed.

What size workshop shed do you need?

A bench and hand tools can fit in a much smaller space than a saw and long timber. Work out what needs to move inside the shed before you choose a footprint.

Start with the work you do most often

For repairs and hand tools, measure the bench depth, the distance a drawer opens and the space you need to stand in front. A wall-mounted tool board can keep the bench clear. If you work with bikes, mark the footprint with the bike on its stand and check that you can get to both sides.

For woodworking, lay out the longest piece you expect to cut. A saw needs clear space on both sides for the workpiece. A bench against a wall may suit hand tools, while a mobile bench can leave the middle of the shed open when you need it.

Measure the route in as well as the floor

Measure the widest part of any bench or machine that will go in assembled. Compare it with the clear door opening on the exact product page. Include the approach outside and any turn needed just inside the doors. Use the external footprint for the base and the internal space for your layout.

Check where the roof is lowest

An apex roof is highest down the middle. A pent roof slopes from one side to the other. Compare the internal height where you plan to stand with the height of tall shelving, drill presses or stock you need to lift. The highest point on the drawing only applies to part of the building.

Before you choose a workshop shed

Mark the bench, door swing and main route through the workshop.
Measure the clear door opening against your largest assembled item.
Check the internal height where tall tools and storage will stand.
Ask us about the proposed floor loads if you plan to use heavy machinery. Heavy Duty upgrades the walls. The floor and frame use the standard specification.
Budget separately for any bench, shelving, lining, extraction and electrics you need.
