Home improvement stores like Lowe's and Home Depot probably have books with project ideas:

A local library may have similar books, but there are probably good online sources worth browsing as well.

Make sure you don't run afoul of any local building codes, though…that the shed's not too close to the main house, too close to utility poles, and so on.

Good luck.

This is a link to a post on a person building a shed/barn and what you all need to consider

Do your plans need to be drawn up by a certified architect ?

Why Brick??? it's more costly than wood………

Sometimes they will accept just a sketch with some rough dimensions. They usually aren't looking for a full set of architectural prints, especially for a small shed.

home depot or lowes

what ever do you need plans for building a shed just buy 2"x2" timber and some shiplap and start nailing

go to a place where they sell sheds ..and find the shed size you want …have a tape with you and spend some time checking it out ..it cheaper to buy a new one than to build it yourself

A couple of other places to look at is

Homebase,Jewson,Focus,B&Q, depending on the size you require they are quite easy to construct so good luck with your initial plans.
