I've been thinking a lot about arches lately, especially in connection with building brick walls, an increasingly interesting construction method for new architecture. If you have an ideal of the true construction of a building being visible, as I do, you have you use either arches or lintels to cover any spans, for example for windows and doorways. You could of course, as many do, fake the whole thing by using hidden steel lintels, covered by the bricks, but that is in my opinion a cheap trick, unworthy of an architecture with ambitions beyond a certain wow-effect. A Norwegian example here, from the otherwise rather tasteful Bøler church, by Bjørndal/Hansen Architects A/S:
*Sigh* Back to the arches. There are many kinds of arches to be found, and they're all suitable for different situations.
Parable or catenary arches may be good for a gateway, or a building you want to look soaring and strange,
a semi-circular arch may be suitable for a solid and classic look,
the segmental arch is good for informal red-brick architecture,
the right-angled flat arch or jack arch (there's also a variant called french arch) can be used in architecture with a geometric or minimal expression,
and the four-centred ("tudor") arch may be fitting if you're a hardcore romantic,
perhaps combined with some sort of pointed ("gothic") arch.
Still, I think one of my favourites (What's your "favourite arch"? God, I'm such a geek.) is the three-centred arch. This gentle shape creates good vibrations all around, feels earthbound and yet poetic, and doesn't require great height.
The first place I thought of that uses these, is my former school, the eminent Nansen Academy in Lillehammer.
The old school building, originally a private residence built in 1918, features three-centred arches in the ground floor windows of the entrance facade. There's also a tiny side building, connected to the main volume via a very short arcade made up of a couple three-sided arches.
It seems this shape was very popular in early 20th Century Norwegian architecture, but it seems to have more or less vanished around 1925. Now, how do you construct this three-centred arches, you ask? You already love them that much? That's good. Here's a youtube video with a very simple explanation:
Now, go ahead and design your own!
