I am new at gardening and I want to get a new clean looking metal shed
(because cheaper than wood and plastic sheds).

My family want me to buy an expensive kind of barn or shed but they
just spend my money, they don't earn it. I am the one who works hard.

So, I will get a metal shed

But it will not have atmosphere. How can I make it look pretty in
winter and summer?

If it looks good and has atmosphere, my family will get out of my hair
too.

Can I grow something over it or do you have other ideas?

Metal sheds become very hot on warm sunny days, the heat is radiated
and anything you plant in close proximity will cook.

Metal sheds are not necessarilly cheaper than wood. Granted there are
metal out buildings that are well made and will last for many years
but they are also quite costly (ie. Morton Buildings and others of
that type). But with the typical el cheapo hardware store metal shed
you'd be lucky to get five years before it looks like an old rusted
sardine can... they are so poorly made they can barely support
themselves let alone shelving and tools, a few gusts of wind adn they
buckle. Whereas a home made wooden shed is not very expensive and if
some thought is given to choice of materials and construction it can
easily last a lifetime. Providing the labor yourself there is no
reason why you can't have one of those fancy schmancy $3,000 ready
made wood jobs for under a grand and built twice as strong.

Most often cheap is expensive.
