The renovation, which focused on the living-dining-kitchen area, strikes a balance between intimate and inviting, hence the project's name, the Open/Private apartment.

The Floating Farmhouse’s semitransparent addition has a roofline that matches the pitch of the original 1820s farmhouse. A porch, tucked under the side eaves, is cantilevered over a stream that runs through the property. Ikea loungers are illuminated from the interior by commercial gymnasium lights repurposed as pendant lamps.

The apartment's entryway features a hidden storage wall and media console.

The new volume houses the dining area, which includes stairs to the bedrooms. The table is from Blake Avenue and the walnut chairs are from Room & Board. “You don’t want bright colors to take away from that relationship between the interior and the exterior,” Walker says.

The living room and dining room were originally separated by a central fireplace, which interior designer Nicole Hollis removed to create this great room. She installed a modern, custom eight-foot-long open gas fireplace in the living room, equipped with sensors that automatically turn it off when someone gets too near to the flames.

The owners toured this home, which surrounds a mature tipu tipu tree, while visiting relatives for the day. The brick is original to the 1947 construction.

Sliding doors by Quantum were made to look like the original panes that couldn't be saved, and they lead to a fire pit outside.

A double-height space encompasses the kitchen, dining and living area, and features 36-feet-wide glass doors that pocket into southern and northern walls.

The kitchen opens to the elements thanks to sliding doors from C.R. Laurence. The anigre in the kitchen is the same employed in the master bedroom.

In the sleek kitchen, the white Ikea cabinet uppers seem to disappear into the wall, while the bases get a distinctive custom walnut wrapping. Flanking the cabinets are open bookshelves, which provide secondary function as a spacial divider for the children’s play area. A Dornbracht faucet sits on a slab of Vermont Olympian White Danby marble, which is also used for the island and backsplash.

In order to maximize light, even the upper section of the bathroom walls are transparent, meaning anyone taking a shower can be seen from the living room, but only from the neck up.

“A building can have far greater impact than the space it stands in.”—William Carpenter, architect and resident

New zoning allowed for a zero-lot-line structure, but required a public storefront, which Carpenter uses as an art gallery.

Two smaller, adjacent structures house autonomous bedrooms, each equipped with a full bathroom.

The neutral color palette extends to the kitchen, which is overhung by several pendant globes.

The main bathroom is only partially separated from the sleeping area by a glass partition. The absence of opaque walls creates a feeling of openness and cohesion in the bright mezzanine space.

Soheil steps into the music and screening room, which is concealed behind a masonry-veneered door. “We were able to hide a lot of the square footage below the main level, but not in a way that would hurt the design,” he says.

An installation by Willem Cole hangs in the gallery, which leads to an open stairway to the office and private bedrooms upstairs.

Designed by Jagoda, the door swings open to fit in front of a bookshelf.

The resident, a Tokyo transplant, commissioned architect Tadashi Murai to create a fully-equipped structure that comes with its own power, heating and cooling, water, and waste-disposal systems.

Joaquin Altamirano and Silvia Martín worked with Daniel Bergman Vázquez of Estudio Untercio to create an open-plan oasis in an apartment building in central Madrid. Estudio Untercio designed the medium-density fiberboard cupboards, which are coated with lacquer paint matching the ceramic-porcelain countertops. The tubular hood above the island is by Teka.

“There is a lot of glass so you can enjoy the view and the outdoor lifestyle even inside,” Henrik explains. “You live in the middle of the weather somehow. It’s a really harsh environment, as you have these southwesterly winds blowing through the house. But it is really beautiful as well.”

See Arch restored the exterior fireplace wall and painted it a deep blue hue to match the repainted blue timber cladding.

Despite their dark color palette, black and white kitchens can still feel bright. This tiny kitchen perfects the art of chiaroscuro with white shiplapped walls, custom-built open shelves and dark concrete floors. The owners selected sleek faucet fixtures by Santec and a sink by Blanco to complement the white laminate countertops. The stainless steel appliances include a Bertazzoni oven, Fisher & Payel refrigerator, and Thermador dishwasher.

The lower floor houses a spa, gym, and office. A built-in bathroom by Espace Cuisine includes a sauna.

After a day at the beach, an outdoor shower tucked toward the back of the house allows everyone to rinse off without tracking sand indoors.

“Parker was dipping brass faucets into his magic solution and Jan was like ‘what are you doing, it was so shiny and beautiful!” laughs Duwayne.

Amending Meeuwissen’s early request for an open bathroom space, the architects devised a more private chamber with an overhead skylight and walls in stone tile from Intercodam Tegels.

Nakada works from an Alvar Aalto table in the living and dining area, adjacent to the kitchen. He saved on some elements, such as the plywood cabinetry, and splurged on others, such as the Finn Juhl chairs and Vilhelm Lauritzen lamp. A skylight beneath the angled roof allows in a sliver of constantly changing light.

The indoor pool adjoins the main house, and features a pair of Easy Chairs by Jørgen Høj and Poul Kjærholm.

In the kitchen, Walker continued an earthy color scheme. The range and wall oven are by BlueStar, the hood is from Zephyr, and the island is Caesarstone.

At a home in California, wood and glass take the lead, including wood drawers with cutout pulls for a custom but simple look.

Brammy and Kyprianou hung Koura pendant lights by New Zealand designer David Trubridge above the dining area. Their organic forms and diamond-shaped shadows create intimacy in the vast space. Among Bilardo’s contributions were the black tulipwood cabinetry and ceiling and the cantilevered concrete countertop that appears to go through the glass wall.
