Characterized by charm, good looks stripped down to the bare essentials, a two-story mountain retreat embraces the beauty of imperfection of brutalist architecture. From a distance, the rough appearance of raw concrete enhances the building’s exterior and façade rising above terraced contours that follow the natural descent towards the lush green landscape below.

Thanks to trees creating a camouflage privacy screen, a brutalist style mountain retreat merges harmoniously into the dark green of a wooded hillside outside Batangas City, the Philippines.

Located in Batangas, a city two hours by car to the south of Manila, the quiet vacation getaway named “Casa Borbon” is the brainchild of Cali Architects, an architectural practice based in Baguio City. It offers 77 square meters of living space nestled among trees and wooded hills. It was a difficult job, but the design team led by Amon Cali was able to create a home that merged into the countryside, a place advocating thoughtful use of the landscape and keeping the environment exactly like they found it.

Made for cozy simple living, the brutalist style home boasts generous wall openings that admit plenty of natural daylight and cool breezes into the interior. As the architect intended, it exudes an air of raw, vibrant personality evidenced by what appears to be bare concrete surfaces and stark geometric shapes. By emphasizing honesty and natural materials, it blurs the boundaries between indoors and outdoors; meanwhile, treating functionality as more important than architectural embellishments.

Stark geometric shapes paired with the exterior devoid of embellishments create a unique look that gives the home warmth and a touch of nature.

But there is more to it than meets the eye. Where appropriate, polystyrene wall cladding is installed. It’s a lightweight material that’s resistant to water and moisture, plus it’s able to withstand a wide range of extremes of the seasons. Because it’s easy to install, the builders were able to complete the project in just eight months.

Taking everything into account, the house plan embraces minimalist interior design. On the ground floor, the dining room at the center gives an impression of the positive energy of family life. Nearby, tall glass walls separate the living room from a small dipping pool with poolside deck furniture. The second floor holds a more private area consisting of a sitting room and two bedrooms with balconies overlooking breathtaking landscapes.

Generous openings on the second floor balcony allow air to flow in and out freely, creating the perfect chill-out zone with a view of the surrounding landscape.

From architectural viewpoints, Casa Borbon is unique in that the second floor can be accessed via stairs located both inside and outside of the house. Indoors, a spiral staircase built of steel connects downstairs to upstairs. Outdoors, another set of stairs leads to the second floor and continues to the rooftop deck hemmed in by planter boxes for gardening.

For privacy reasons, an outdoor set of stairs provides direct access to the second floor without passing through the interior of the first floor.

In a few words, it’s well-thought-out home that conveys a great deal about brutalist architecture, one showcasing the rawness of materials fit to perform in the Tropical climate prevailing in Southeast Asia.

The lush appearance of plants growing vigorously makes the house entryway warm and welcoming in contrast to the rigidness of bare concrete walls.

Small space? No problem! Here’s a tall and slender concrete home built and furnished in a modern style. Plus, it transforms into a verdant oasis that’s beautiful and warm in a class of its own. Albeit small in size, the house boasts the relaxed interior ambience bedecked with houseplants thriving in containers scattered throughout. Nearby, the walls painted a cool-toned cream are lined with troughs where leafy exotics grow, creating an atmosphere for calm.

The tall and slender concrete home rises amid shade trees in lush full bloom that provide indoor thermal comfort all year round.

Located in Bac Ninh, a city just an hour’s drive to the northeast of Hanoi, it’s a small family residence ingeniously devised to deal with space constraints and limitations. To make the most of the situation, the four-story concrete home occupies the full extent of an 80-square-meter plot. The elongated rectangle measures 4 meters wide and a whopping 20 meters long.

What makes the home stand out from the rest is its front façade adorned with shade trees and lush vines thriving luxuriantly, keeping the interior cool and comfortable. Walk in the door and you come to a living room with minimalist flair and a dining room in dark brown lying further inside.

One thing for sure, nature permeates through the entire home. Overall, the effect is impressive thanks to space design solutions created by a team of architects at the design studio Kien Truc NDT based right here in Bac Ninh.

The house’s external envelope boasts the simplicity of clean lines and geometric shapes with muted and earthy colors typical of modern style homes. Directly overhead, concrete beams spanning an opening at the top have an obvious rawness feel to them, creating a seamless blend with nearby shade trees in the front yard.

The principal face of the house itself is bedecked with climbing vines that provide added privacy plus freedom from noise and disturbance from the outside.

Interior walls are covered in cement plaster painted a cool-toned cream that’s easy on the eye. They stand in contrast to the exteriors made of raw concrete and brick masonry, resulting in charm, good looks that blend with surrounding landscapes.
Illuminated by an overhead skylight, the stair chamber at the midpoint of the house plan separates the dining room in dark brown from the living room at the front.

According to the design team, by aligning the building with the sun’s path and prevailing wind direction, the house sits facing in the north direction that gets moderate amounts of sun, resulting in indoor thermal comfort even during summer months. This makes it possible to set up outdoor furniture anywhere under shade trees in the front yard.

The living room at the front of the house provides access to the dining room that lies furthest in.

Skylight systems built into the rooftop provide enough light to keep indoor plants alive, creating a pleasant visual appearance.

On top of that, open-concept design admits natural daylight and fresh outdoor air into the home all day. This is achieved by positioning the building slightly toward the rear of the property, resulting in a win-win situation. The house becomes quieter and more secluded, while the front yard gains bigger space for rest and relaxation under shade trees.

A stairway painted white is built flush against the wall, rising above the foyer illuminated by skylights.

The bedroom has en suite facilities enclosed by clear glass for uninterrupted visual continuity.

From a design perspective, the house plan has two parts to it, separated only by a well-lighted stair chamber occupying the in-between space.

To avoid the interior feeling stuffy typically occurring in row houses, the architects installed a skylight system in the rooftop to regulate the amounts of sun and fresh outdoor air streaming inside, turning the ordinary narrow lot home into a salubrious living space.

To create rough textured walls, the home is built of structural concrete with exterior walls made of exposed brickwork that allows climbing vies to thrive. This contrasts with the indoor living space that’s covered with plaster and painted a cool-toned cream, an entirely different story.

Serene surroundings in the semi-outdoor bathroom without a ceiling provide a salubrious atmosphere well-ventilated and well-lit by natural daylight.

An outdoor room showcases the rawness of concrete beams and a garden oasis hemmed in by exposed brick walls, a beautiful sight that blurs the boundary between inside and outside.

In the big picture, it’s a beautiful concrete home made possible by dealing with space limitations in the most practical way. For the design team, because the land is long and very narrow, the only way to go is up and hence the tall and slender home bedecked with lush vegetation as you see it.

More importantly, it’s made for a green lifestyle that’s simple, power efficient and architecturally pleasing.
