Wooden playhouse - Preparation...

[Peter Watson]

Some advice sought...

I've ordered a wooden playhouse to put in the garden. Not very DIY I hear you shout (well it is flat pack and I'm going to put it up!) but lack of time etc.....

The playhouse in question has a resin bonded board floor. I have an existing concrete slab in situ to put it on so do I:

a) Just build it on the concrete base? b) Put some bearers (say suitably treated 2x2) on the concrete and put the playhouse on them? c) As b), but put a plastic membrane between the bearers and the floor?

b) or c) sound like the best options as the bearers can always be replaced if/when they rot but to membrane or not?

Any thoughts?

Thanks,

Peter

Anything that will hold water in puddles is a no, no, so you need a layer under the shed that will allow water to drain away from the underside as quickly as possible so it doesn't sit on the timber.

So your plan "B" sounds the most suitable.

Hi,

What about putting it on bricks or blocks? If the tops can be coated or covered with something waterproof, even better.

cheers, Pete.

Hi Pete,

I hadn't thought of that as an option...

The kit has now been delivered, and it actually comes with bearers to go under the floor so I guess I'll just use them....

It is frequently worth not using the floorboards that come with the kit. They will undoubtedly be around 5mm thick and bouncier than a trampoline assuming you don't manage to put your foot right through. I'd get new 22mm T&G, plywood or flooring grade chipboard instead, unless the supplied flooring really is usable.

Hi,

Does water drain off the slab when poured over it or does it form puddles?

If the latter it might still be worth putting some thin blocks or something like that under the bearers.

cheers, Pete.

Fortunately the slab is flat but not quite level, so water runs off OK.

Cheers,

Pete
