Kotilo – also aptly dubbed the Seashell House – has had architecture enthusiasts spinning in their seats with its wonderful, whimsical, winding design. Scottish architect Lewis Martin has revealed this wonderful house design on his website, Lewism, where he offers a tour of the work of modern Finnish architect Olavi Koponen. Designed by Koponen as his own private home, this unique house in Espoo, Finland, is contemporary creativity at its best. With the hearth at its heart, the entire home literally twists its way around this main focal point. Surrounding the impressive fireplace, a staircase meanders its way from bottom to top, open to the home’s various rooms. The unique design boasts a grass roof and is clad in timber shingles – Larch on the exterior and Aspen on the interior – which adds to the home’s organic appeal. Olavi Koponen.
