Modular Flexibility

This design is known as a modular Apex Combi Summerhouse. Panels can be positioned anywhere you like, enabling you to design the perfect door/wall/window setup for you. The storage shed can be positioned on either end, and generally comes available in 4ft or 6ft wide (4ft wide only on the smallest buildings).



This Apex Combi Summerhouse is supplied pre-treated with a quality, brown (golden oak), non-toxic preservative base coat. Each panel is treated inside and out (including end grain, tongues, grooves and cut-outs. This is a long-lasting preservative, allowing you to use the shed straight away. There is no need to paint for the first year, but you can change the colour or over-paint at any time if you prefer.


Doors, Locking System & Windows

The joinery-made double doors on this summerhouse are great… they are pre-fitted with toughened safety glass, are fitted internally with a rim-lock c/w mortice key for convenience, and have an easy grab handle, non-rusting, zinc galvanized hinges, and a turn-button are supplied as standard onto a 1034mm (40″) wide double door.

Windows are made from strong, secure toughened safety glass, and they are pre-fitted onto a non-rot window sill. Alternatively, this summerhouse can be supplied with fewer window units if you prefer (at no additional charge).

The storage unit on the end can be 4ft or 6ft wide, and comes with a solid shed door, c/w internal lock with a key. The shed door can be fitted on the back, front or side, and it can be upgraded to a double door if required.



This Apex Combi Summerhouse is supplied ready to go down onto an existing solid base made from concrete, slabs, or decking, however if you don’t have anything in place, you can purchase a Power® Base. It is pressure-treated, and is fitted below the summerhouse to create a solid base for your building to sit on, whilst allowing ventilation below your building.

Please ensure that regular general maintenance is carried out on all moving parts, and inspect the roofing felt regularly (especially before and after storms), and replace when required.
