How to build your new Challenger Shed


So, you’ve just received your brand new Challenger shed, that flat-packed bundle of excitement is sitting there, just waiting for you to get building. This article should give you some advice and instructions on preparing, building and looking after your shed.

What do I need to do before building my Challenger Shed?

The prepared D.I.Y’er is the smart D.I.Y’er, and as your Challenger is going to be with you for the next quarter of a century, its important you give it the best possible start in life. As with all buildings, it is essential that you provide a firm and level base on which to build your shed. The very best base (and the one we always recommend) is a concrete base.

Top tip: if you’re base is made of concrete, we recommend it does not extend beyond the dimensions of the shed. This avoids rain water collecting on the base, and in the words of Mary Berry “nobody likes a soggy bottom”. If you’re building our apex 6×4 shed, we recommend a base size of 1800 x 1200mm.

What equipment do I need to build my Challenger Shed?

All the fittings and everything you need to build your shed are included with your Challenger, so you’ll just need to have a basic tool kit to put it together (a hammer, tape measure, a Stanley knife, clear mastic sealant for the window pane & a screwdriver). We recommend an extra pair of hands for the larger sheds and a good supply of tea and biscuits.

How to build a Challenger Shed

  1. Place the floor section on the base you have prepared and fix the back panel to one side panel, screwing through the vertical battens of the back panel into the battens on the side panel using 3 screws. Repeat this process when fitting the other side, also using 3 screws.
  2. Fix the front panel (this is the panel with the door) to the 2 side panels using the same method as in the previous step, using 6 screws.
    Top tip: After all the panels are fitted together, make sure it is all square and the cladding overlaps the floor.step2
  3. Place one roof panel on to the top of the shed. The batten will fit into a central recess on the front and rear panels.Repeat this step with the other roof panel. Screw each roof panel into place on top of the shed using 7 screws for each panel. Once the roof is screwed into place, fix the panels to the floor section using 3 screws for each side panel and 2 screws each for the front and back panels.step3
  4. Fit the long fillet in the gap between the 2 roof panels.step4
  5. Fit the 4 x corner fascias using 3 x 40mm nails in each fascia.


  6. Now it’s time to cut your felt. Measure and cut 2 lengths of felt by measuring the length of the roof panel and adding an extra 100mm. Once the felt is cut lay, the pieces to overhang the side of the roof by at least 60mm.
  7. Nail the felt around the outside of the roof every 10 cm.
    “Perfection never ‘felt’ so good”
  8. Place the glass panel into the window frame using a suitable sealant, then nail the 20mm x 20mm interior beading strips into place starting with the bottom strip.

  9. Fit fascia pieces into place on front and rear of the shed, and screw into place with 8 screws in each panel (2 screws per panel)step9

Voila! You have just built your new Challenger shed. Before you start moving in your assortment of tools, pots, buckets and general gubbins, we’ve got a few extra tips for keeping your Challenger in tip top shape.


4 things to consider after building your Challenger Shed

“It’s good to touch the green, green grass of home…” – Tom Jones, 1966

As Tom Jones stated in his 1966 hit, it’s good to touch the green, green grass of home. However, it’s better that not too much of it touches your shed. Keep the area surrounding your shed clear of any grass or vegetation (including pruning any trees overhead)

“Pressure, pushing down on me, pressing down on you…” – Freddie Mercury, 1982

Freddie mercury was right to worry about pressure, but can rest assured your shed has been pressure preservative treated. This means it’s designed to prevent rot and insect attack for up to 25 years, as well as to give the timber an extended and low maintenance service life. This treatment is not intended to perform as a waterproofing agent.

“I see a red door and I want it painted black…” – Mick Jagger, 1966

What colour should one paint one’s shed? Whilst black might prove a controversial choice (sorry, Mick) we recommend painting your shed with Barrenttine Shed and Fence treatment. Available in 5 litre tins in four natural colours (Dark Brown, Evergreen, Harvest Gold & Red Cedar). These can be bought at checkout from our website, or in any of our branches in Cobham, Woking, Farnham, Maidstone and Gloucester. When you add a Challenger Shed to your basket on our website, you’ll see a range of shed accessories to browse, including shed treatments.

“I’ll sing my song to the wide open spaces…” – Roger Daltrey, 1971

We recommend a minimum of 400mm (15″) clearance around all sides, although having 600mm (24″) allows more comfortable room for painting and any maintenance.
