I think It might actually be much easier to separate favourite buildings, spaces, architects etc up by category. I think it might be a very useful exercise to discuss, reference to buildings which do well in the Irish natural landscape. As many people seem to have their favourite piece of architecture, as some type of building in the landscape. And then perhaps discuss favourite open spaces on a different thread.
One thing which intrigues myself about building in the countryside, is the changing light and views, you see through your window each season. Bearing in mind, that Ireland doesn't have distinct seasons, like say Denmark etc - Snow etc. - you still find gradation of light, and some changes in nature. I quite like these images in an Irish context, restraint of materials and expression etc - strong and understated, like the landscape itself.
2 Winter light and views. Cold, hard, clear light/weather.
1 Spring light and views. Thawing out, everything soaking wet, hear the grass growing.
3 Summer light and views. Hazy, aromas, green-blue blinding light.
4 Autumn light and views. Sharp, golden.
Btw, I have spoken a small bit about this phenomena of light and design in relationship to restaurant premises in Temple Bar. A totally different context to the Irish landscape, but much the same idea in many ways.
