The FSC Sentry Box is a compact garden storage shed which is ideal for storing your long or tall garden items. It has a single door secured with a pad bolt and oriented strand board (OSB) solid sheets on the floor and roof making it both robust and durable. Manufactured using FSC-approved timber, this quality shed is constructed around 2.7cm x 3.2cm framing and 8mm tongue and groove cladding.

With an apex shed, the roof is in two wooden sections which meet at the highest point to create an upturned ‘V’ shape so that the maximum height of an apex roof runs centrally from the front to the back. The height of the eaves is designed to allow for generous storage at the sides while allowing for optimum standing height in the centre so that you can work comfortably.


This product comes untreated, so it should be painted with a good quality preservative once it has been installed, and you should continue to maintain it every year or two, in accordance with the manufacturer’s instructions. This will ensure that your shed will last for many years. Box includes:

  • Roofing felt
  • Manufacturer's 10 year anti-rot guarantee

The perfect shed for a little garden Sara on 4 July 2018

My handyman found this shed easy to build using the instructions. With a couple of coats of paint to protect the wood it fits perfectly into my small garden and is a great storage solution for my garden tools. Fair value for money..

Solid shed N Hill on 16 October 2013

I bought this shed after purchasing the Sentry Apex shed last year, as I needed a bit more storage space. The shed is well made but the timber is not as well finished as the Sentry shed with a few rough faces and nail holes, but it is much more robust. I gave it a quick sand down and filled some of the nail heads that were noticeable once it had had its first coat of paint. There is more construction involved with this shed as you have to fix the roofing felt and cut the fascia boards to fit. This is pretty easy following the well written instructions. It is recommended that you treat the shed after its built . I've fitted mine out with shelves at the top with space below to store garden seats. I'm very happy with this compact little shed and it should last many years having been well constructed.
