A RIBA winner in 2015 this contemporary architecture sits at the heart of the Waddeson estate in Buckinghamshire

Two wedge shaped buildings face each other

The main house with a dining and drawing room, a study and main bedroom

There is a flint grotto with a mirrored ceiling

A river flows under the internal walkway

The first floor and annex has more bedrooms with terraces

The interiors of the house were designed by David Mlinaric incorporating natural fabrics, warm colours and neutral shades
