There's a book called "Country Flying", buy Geoff Farr, which I think you can buy from the PFA shop - costs around a fiver. It gives some very clear advice on how to make your own.
Don't know about the UK, but..... .BEWARE, if the T hangar you build is not an "approved" plan with a proper building permit, your hull insurance may be at risk if it collapses on the plane, due to high winds, for example.. .Better safe than sorry.
