A flat-pack shed can pass through an opening much narrower than the finished building—but the largest delivered panel must fit. Get that panel’s dimensions before ordering, then measure your narrowest opening and every turn. The size on the shed’s nameplate will not answer the delivery question.
Ask what will arrive
Request the dimensions and weight of the largest delivered item, whether it can be unpacked before carrying, and which orientations the supplier permits. Ask where the delivery service ends and whether moving the parts through the garden is included.
Measure the actual openings
Record the clear width and overhead clearance at every narrow point. Include latches, hinges, steps and low branches in the route notes. Do not substitute a gate’s advertised panel width for the usable opening.
Look beyond the gate
Sketch changes of direction and spaces where people would need to stand or turn an item. A component that fits through a straight opening can still be impossible to move around a corner or carry safely. Tell the supplier about slopes, soft ground and steps.
The fit checker compares rectangular face orientations against an opening. It cannot assess a complete route, item weight, a diagonal manoeuvre or safe manual handling. Treat its result as a way to prepare the right measurements for the supplier.
Delivery and assembly can end in different places
For Keter’s assembly service, the customer must position the boxes near the installation area; its fitters do not move them. Ask the seller how your delivery service connects to the booked assembly. Check Keter’s installation requirements.
Before ordering
Send the relevant measurements to the supplier through their normal enquiry route and keep their delivery confirmation with your order.
