When moving to Galway you need to consider maintenance when you see your new garden.
Our house is on about half an acre. That's a lot of grass. No problem. But....(there's always a but)...we never thought about a garage to store a mower, a rake, shears, etc. etc.
So, if you are buying a house consider the size of the garden, how long it will take you to cut and manage, and where you will store whatever you need to do that.
On a separate note about gardens - considering the recent downpours throughout Ireland, be sure to also check your garden and house are not in the floodplains of a river or lake. Google maps can be handy for finding what waterways are near you - http://maps.google.com/maps?f=q&hl=en&geocode=&q=galway&ie=UTF8&ll=53.445535,-9.063721&spn=1.452647,3.383789&t=h&z=8&iwloc=addr
Also consider how much time you will actually get to spend in the garden. If you can't spare the time to manage it, do you want the extra expense of having to get someone in to do it?
A garden is a big commitment. This is especially true when you have just moved to a new city, or even if you just need to get your first house to the stage you can call it home. It takes time, and if you are based in Galway that means a lot of gaps between showers too!
On the other side of that, a big garden which is well laid out and maintained can add vastly to the value of your house, as well as how much you can enjoy it.
Summary: when you make your list of things to consider when finding a home, be sure to include your ideal garden - be that small or large, paved or bedded.
