Villa Kogelhofan is a minimalist house located in The Netherlands, designed by Paul de Ruiter Architects. Villa Kogelhof is designed based on complete autarky: therefore the house is energy neutral. By using several techniques, the villa will have a comfortable climate all seasons, whilst being extremely energy efficient. It was an important wish from our client to create a simple, abstract, yet spectacular villa. The result is a composition; consisting of two square stacked volumes: one underground and one floating above ground. It is designed as an uncompromising glass box, supported by a steel V-frame.
