Keep the base clear of standing water and allow practical access around the building so the timber can dry after wet weather.

Choosing Pressure Treated Sheds in Portsmouth
Pressure treatment helps protect timber over the long term, but the building still needs a level base, sensible ventilation and normal care. Compare wall construction, framing, roofing, doors and guarantees rather than treatment alone. Pressure treatment reduces the timber maintenance burden, but drainage and airflow still matter. Keep the base clear of standing water and allow practical access around the building so the timber can dry after wet weather. For Portsmouth deliveries, the exact postcode, access and any installation requirements are confirmed before the order proceeds.
Delivery, installation and preparation
Delivery options vary by product and postcode. Installation is available on selected garden buildings. Always check the product's base requirements before ordering and make sure there is suitable access to the delivery or installation area.
How do I choose the right size?
Measure the usable garden area and allow space for access, doors, roof overhangs and maintenance. It is usually better to allow some spare internal storage space rather than buying to the exact minimum.
Can installation be arranged?
Installation is available on selected buildings. Availability depends on the product, postcode and base conditions, so our team will confirm the details before the order proceeds.
Do I need a base?
Yes. Every shed or garden building should stand on a firm, level and well-drained base. The base is the foundation underneath the building; it is different from the internal floor supplied with some sheds. Common options include concrete, paving slabs, timber frames and plastic base systems. Shop shed bases →
Are wooden sheds waterproof?
Wooden garden buildings are designed to be weather-resistant rather than completely waterproof. Correct assembly, a level base, a properly fitted roof covering, timber treatment and ventilation all help keep the building dry and performing well. Read our wooden shed care guide →
Do I need planning permission?
Many garden buildings in England can be installed under permitted development rights, subject to height, position and coverage limits. A key rule is that a building within 2 metres of a boundary is generally limited to 2.5 metres overall height. Listed buildings, flats and some restricted or designated properties need extra checks.
