How to build your new Surrey Shed

How to build your new Surrey Shed

So, you’ve just received your brand new Surrey 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 Surrey Shed?

The prepared D.I.Y’er is the smart D.I.Y’er, and as your Surrey shed is going to be with you for the next quarter of a century, it’s 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 your 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”. For example, if you’re building our apex 6×4 shed, we recommend a base size of 1800 x 1200mm.

What equipment do I need?

All the fittings and everything you need to build your shed are included, 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 Surrey 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.Garden Shed Installation - Step 1
  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.Garden Shed Installation - Step2
  3. Place one roof panel onto 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.Garden Shed Installation - Step3
  4. Fit the long fillet in the gap between the 2 roof panels.Garden Shed Installation - Step4
  5. Fit the 4 x corner fascias using 3 x 40mm nails in each fascia.Garden Shed Installation - Step5
  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 so they 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.Garden Shed Installation - Step 8 - Fitting Window
  9. Fit fascia pieces into place on the front and rear of the shed, and screw them into place with 8 screws in each panel (2 screws per panel)Garden Shed Installation - Step9

Voila! You have just built your new Surrey 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 shed in tip-top shape.


4 things to consider

“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. However, 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 and Maidstone. When you add a Surrey 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.

5 Things that are not as tough as a Challenger Shed

1. Chuck Norris

There are many overblown rumours about ‘Walker, Texas Ranger’ star Chuck Norris, from the slightly plausible to the downright ludicrous. We say “Chuck, you’re not so tough!” Chuck Norris may be able to make a snowman out of water, but does Chuck Norris have a heavy duty, mineral felt waterproof roof with 7 years’ life expectancy like a Challenger shed? We think not.

2. Climbing Mount Everest

OK, so you’ve climbed 29,000 feet of mountain through a snow-ridden blizzard, pretty impressive. Want to know something even more impressive? When you get to the top you might just find a Challenger shed, standing strong against the elements. If you’re really lucky, you’ll find Chuck Norris inside it, sheltering from the cold.

Every Challenger shed comes flat packed with full self-assembly instructions and a comprehensive fitting kit (you won’t even need to dress for the cold)

Everest? Easy

3. Selling a used mattress

They say that people spend up to 25 years of their lives sleeping. A quarter of a century’s use can take its toll on ‘old bouncy’. It’s served you well, but the time has finally come to pass your mattress on to the next life. Unfortunately, selling a used mattress complete with broken springs can be harder than killing two stones with one bird (something else Chuck Norris is rumoured to be capable of). Thankfully, the high quality 15mm Scandinavian redwood on the Challenger shed is 100% pressure treated for up to 25 years’ protection and beyond (so you can spend more time in the shed, and less time in bed).


It served you well, but its time to move on.

4. Making Baked Alaska

Ah – Baked Alaska! Everyone’s favourite meringue topped ice cream cake is a notoriously tricky dessert to master. Oftentimes beginners can find their Baked Alaska representing the wake of a snowplough carefully slopped into a bowl. Alas. Thankfully, building your Challenger shed is much more straightforward, and our expert team @Chall_Fencing or in your local branch is always on call to give you a helping hand. Unfortunately, they can’t help with dessert.


Baked Alaska? No problem.

5. The Terminator

Another famous tough guy, the Terminator spends a lot of his time beating up Cyborgs, saving the future and “Getting to the Chopper”. That’s all very impressive, but does the Terminator have a 25mm tongue and groove floor and roof for extra strength? We don’t think so. We’re even more certain he doesn’t have galvanised fittings to prevent rusting. Don’t worry, Arnie. We’re always on hand to give advice.

Our high quality Challenger shed range is manufactured from Scandinavian Redwood, and is 100% pressure treated to protect it against wood decay and insect attack for up to 25 years.


The Terminator? Not so tough.
