Designed by Metropolis Design architects, this house gets it's name from a term used in astronomy. Colure are great-circles (a circle whose centre is also the centre of the earth) which bisect the ecliptic plane at the equinoxes and solstices. The circular cutouts in the concrete slab, a feature of the design, set off the rectilineal structure, and are mimicked throughout in furniture and light fittings. The most striking function of these cutouts is how they create a spotlight that creeps across the living space each day, changing incrementally each day as the earth travels around the sun and the seasons change. You'd have to live in the space for a least an entire year to appreciate the full effect of the design. An added bonus is the circles also allow you to see the mountain and sky through their negative space.
