About our Power pent potting sheds
A pent potting shed is the answer when the building must sit against a wall or fence. The single slope tucks flat under an eave, and rain sheds off the front away from whatever stands behind. We stock 27 Power pent models, all with a glazed growing side and a boarded store under that low roof. If your shed stands in open ground and you want more headroom, the Power apex range is the better pick. To split growing and storage into two doored bays, see the Power combi range. For a hand-made building in heat-treated ThermoWood, look at the Swallow Jay and Swallow Rook potting sheds.
We fit the pent range where an apex simply will not go. The 6ft 6" ridge slides under a kitchen window or low fence line. The flat back leaves no awkward gap to a wall. Same timber, same staging, same glass as the apex. You only give up a little headroom for a shed that fits a tight spot.

Pent or apex: which roof should you choose?
Choose pent when the shed sits against a wall or fence, because the single slope fits flat under an eave. Choose apex when the shed stands in the open and you want the extra standing headroom of a central ridge. Both Power ranges share the same timber, staging and glazing, so the roof is the main decision.

Matt's pick
For a tight side return, the 6ft-wide pent at £546 is the one we fit most. It holds a working bench and a row of tools without crowding the path beside it. Go narrower at 4ft only where the gap really demands it.
How big a potting shed do you need?
Match the width to your work, not just the gap. A 4ft-wide pent suits seed-raising and hand tools down a narrow side return. A 5ft 10"-wide pent gives room to turn with a tray and store compost on the floor. Lengths step up in roughly 2ft increments, so a longer run adds staging without widening the footprint.
Do you need planning permission?
Most gardens need no planning consent for these sheds. The 2028mm ridge sits well under the 2.5m permitted-development limit near a boundary. That is part of why the pent suits a tight fence line. Check your own plot if it sits on listed or conservation land. Your local planning office confirms the detail for your address.
Matt's installation tip
Leave a hand's width between the flat back and the wall behind it. The gap lets air move so the rear boards dry after rain. It also gives room to re-treat the timber every couple of years. Build on a firm, level base so the door does not bind. Decide which end the door goes before you start.

Frequently asked questions
Will a pent shed fit against my house wall?
Yes, the single-slope roof is designed to sit flush against a wall or fence. Leave a small gap at the back so the timber can dry.
Is the staging included?
Yes, full-length two-tier staging is fitted as standard. It runs 500mm deep along the glazed side, ready for trays and pots.
Which end does the door go?
The door panel fits either end during construction. You decide at build time so the door matches your path or access.
Is the glass safe around children?
Yes, all windows use toughened glass measuring 457mm x 610mm. Toughened glass crumbles rather than splintering if it breaks.
How is the shed delivered?
Delivery is free to mainland UK, usually within 5-7 working days. The supplier books a slot with you by text before the shed arrives.
