House O, designed by Jun Igarashi, forgoes hallways and interior doors in favor of casually interconnected rooms.

The chic contemporary interiors feature concrete floors and plywood paneling, with black accents that echo the cabin’s exterior.

Found in Seis am Schlern, Italy, this ornate, gothic-style staircase is a showstopper. The black metal tread and railing heighten the home’s drama and elegance. Designed by Italy’s Network of Architecture, the idea behind the detailed staircase design is that the further one ascends, the more it heightens intimacy.

Tucked away on the edge of a small lake surrounded by mountains and topped off with a grass-covered roof, this hunting cabin designed by Snøhetta is made with locally sourced stones. The 376-square-foot prefab mountain hut sleeps up to 21 guests around a central fireplace.

Sleeping nooks that look like the grooves in a block of cheese.

A passage between the walls for hide and seek.

The addition’s two stories of cedar-framed sliding doors and window provide generous views of the house’s prized jacaranda tree. The addition’s polished concrete floor and white cladding extend into the garden, drawing occupants to the serene rear porch. There, they can relax on stools designed by Alvar Aalto and Charles Wilson while admiring the luscious greenery.

Situated on a sloped-site, each renovated space provides a unique perspective and vista to the dramatic natural surroundings. The office, with its stark modern furnishings and subtle artwork, allows the large window to serve as perhaps the most dramatic, singular frame to the foliage beyond.

This living/bedroom space showcases neutral tones and shades of white to contrast the continued use of natural, treated wood surfaces.
