The hot and humid climate in Thailand is inevitable. But where there’s a will there’s always a way. This energy efficient home clearly illustrates that. The old house belonging to Assoc. Prof. Tonkao Panin Ph.D., of the Faculty of Architecture, Silpakorn University was lovingly restored to its former glory. The result is a place of residence that’s very pleasant, airy and well-lighted.

The house floor consists of prefab concrete slabs raised on a solid framework of steel. The lower floor right underneath it is covered with concrete in glossy finishes.

Located on the bank of a canal, the property faced a long-term problem. Flooding tended to happen often. This eventually necessitated a complete teardown to make room for a new home.

“We had full-grown trees on the land, which we intended to keep. So, the architects designed the building around them. Due to some limitations, parts of the old home remained intact. The space where the trees are standing now has since transformed into an atrium,” Tonkao said.

The staircase leading to the second floor has simple looking handrails that match the style of the house.

“I want a home that’s open and airy – a house that breathes, so to speak. The new design calls for a system of wide corridors and ample spaces underneath it. The low land is now filled up to bring it to street level and create semi-outdoor multipurpose room.”

Tonkao chose steel for the main structure because it reduced construction time and enables a flexible construction schedule.

The two-story, L-shaped home splits into two wings located on either side of the warm and pleasant center courtyard. The canopy of tall trees keeps the entire living spaces cool and comfortable all day long.

For indoor thermal comfort, the exterior walls are made of hollow bricks to block the sun while allowing the wind to pass through. Plus, long eaves overhanging the outside walls protect the home from heat waves, while house-on-stilts design improves ventilation.

A sliding door separates the home office and sitting area on the second floor. The two rooms become one when the door is opened.

“We sleep soundly in a compact bedroom. A wide corridor helps when we walk pass each other. Semi-outdoor walkways enable us to keep abreast of current weather conditions and we don’t need air-conditioning,” said Tonkao apparently content with the design.

All things considered, it’s an energy efficient home, one that embraces natural light, increases airflow and makes daily living not only comfortable, but also enriching.

The design of this modern steel house fosters a harmonious relationship between man and mother nature. What presents itself as a chic, cubic steel structure draws its inspiration from traditional homes in the neighborhood and the lifestyles characteristic of the people in a locality.

Modern Steel House
The materials selected for this house are primarily recycled. The use of steel structures enables rapid construction, aligning seamlessly with the Dry Process approach.

For the most part, the house is made of recycled building materials adapted to suit a new use. Among them is the steel structural framing that reduces building time and noise pollution on the job site, making it suitable for dry construction.

The homeowner, Thitiwoot Chaisawataree, who is an architect and professor of architecture at Kasetsart University, shared the following with us:

“My parents wanted to transform the storage building at the back of their house into a relaxation room for hosting friends and relatives. The renovation plan involved dismantling and repurposing parts of the old structures that were no longer needed.

“The plan also emphasized adapting materials from past projects for use in a different purpose. They included hollow cement blocks, glazed tiles, electrical switches and outlets, paint, cast iron decorations, spiral staircases and steel rod fencing. And as the result of all this, a bright and airy modern steel home was created.”

The area beneath the house is spacious and well-ventilated. A long wood bench securely mounted on H-shaped steel framing is a perfect addition to the entrance of the building.

To lower humidity and enhance air circulation in the home, the floor was elevated to a plinth height above the natural ground level. Hardwood flooring materials were scarce. It was fortunate that the homeowner had purchased these materials and stored them for eight years prior.

They included wood planks 20 inches wide, 2 inches thick and 5 meters long that were used to build hardwood flooring. The design stipulated that none should be cut. One advantage of reclaimed timber is its low humidity content and reduced vulnerability to insect infestations.

Lightweight building materials were chosen since the renovated home rests on the original, long-standing foundation. The foundation sits on older pilings, which are shorter and have a limited weight-bearing capacity.

The master bedroom boasts a variety of features, ranging from a workspace and sitting area to a cozy nook for relaxation.

The newly renovated home, spanning approximately 100 sq. m., is spread over two floors. The ground floor encompasses the primary open-plan living area. The second floor, which can be reached through a staircase outside the first-floor corridor, houses a bedroom, sitting room, workspace, and bathroom.

The architect, reflecting on his project, said: “Despite the ceilings being lower than usual at around 2.30 meters, the sitting area feels spacious. It draws inspiration from traditional Thai-style homes which prioritize creating living spaces in harmony with the environment, rather than emphasizing decorative elements.

“With this in mind, even a box-shaped house can be adapted to incorporate such design principles.”

Reclaimed wood planks find a new use as flooring materials on the first level. The use of movable furniture allows for future updates to meet the changing needs for space.

Speaking of the current trend in urban design, the homeowner wrapped up his perspective about this modern steel house very nicely.

“I’ve observed that today, we often face challenges in integrating the environment seamlessly into our home design. We’ve distanced ourselves so much from nature and, consequently, become more reliant on energy for various necessities, such as air conditioning and insulation.

“It seems we’re prioritizing the aesthetics of our home’s exterior over a design that naturally shields us from environmental factors. Over time, when we realize that the house doesn’t meet our needs, we consider expanding our living spaces. Ill-conceived designs can sometimes result in aesthetically displeasing outcomes.”

“Specifically for the Thai lifestyle, a comfortable home is one that’s tailored to the needs of its residents. Even better if the functional spaces are adaptable, allowing for potential future expansions.

“Simultaneously, the Tropical hot and humid climate of Thailand should be a primary consideration in home design. Comfortable interiors stem from design that harmoniously coexist with nature. Well-conceived floor plans ensure optimal air circulation and offer protection from the elements. It’s advisable to steer clear of materials that retain excessive heat.”

This house on stilts in a riparian neighborhood just off of Rama 2 Road represents a confluence of ideas between traditional craftsmanship and modern technology. There is timeless elegance and beauty in traditional design that provides an ample relaxation space on the open lower floor. The second floor features a wood balcony large enough to be used for several purposes, while the third holds a quiet, more secluded living space.

House on Stilts bangkok
The three-story wood and concrete home features a mix of traditional and contemporary designs highlighting simple, clean lines that are easy on the eye.

On the outside, long eaves overhanging the walls of the building protect the interior from the elements, while solid walls shield the home from intense glare of the sun. The result of all this is a comfortable indoor environment.

Nanthapong Lertmaneethaweesap, of the Arsom Silp Institute of the Arts, designed this home as part of an affordable housing program for the institute’s most valuable assets — their teachers. The program has aided the teaching staff in owning a home of their dream, hence the name “Baan Bang-Gru”, meaning houses for the teachers.

He said that for the most part a house plan based on simple design is the most comfortable to live in. That has a lot to do with finding the right balance between functionality and the house’s overall dimensions – or how big it is. Easy living can be achieved without spending a fortune on sophisticated decorative details.

Inspired by the rice granary in former times, the house’s exterior wall features upright studs on the outside and wood paneling on the inside. The hardest part is making reclaimed wood panels fit in with the new design.

Our documentary crew visited this house in the waterside area just off of Rama 2 Road that was famous for its simple lifestyle. We witnessed people go about their business in ways that were distinctive to a riparian community. We also noticed that change was just around the corner.

Overall, the design and build quality of the house represented the combination of ideas between traditional knowledge and technology of the modern era. Interestingly, it was like is a journey through time.

The charm of a riparian wetland. The house at the water’s edge strikes the right balance between traditional and contemporary designs. Here, it makes a refreshing change to be able to live close to nature.

Charatsri Sribumrungkiat, the homeowner, said: “I acquired this piece of land thanks to assistance from the Arsom Silp Institute of the Arts. It was part of an effort to provide affordable housing for the institute’s instructors. The program has aided the teaching staff in buying a piece of real estate at cost price, hence the name “Baan Bang-Gru”, which means the teacher’s home.”

Family members are all smiles with the Thai-style ranch home in the backdrop.

Nanthapong added: “In my opinion, this piece of land has great potential. It affords good views both of the lake and the waterway that runs past the rear of the property.

“The house’s front façade rises facing south, and the building is oriented along the east-west axis. This enables it to reap the health benefits that come with southerly winds.

“The house plan in itself fits in very well with the waterside setting. Its house-on-stilts design provides an ample relaxation space on the open lower floor. The second floor features a wood balcony large enough for multiple functions, while the third holds a quiet, more secluded living space.”

The rear of the house affords a view of lush greenery and a peaceful waterway. The designer puts in a gallery large enough for multiple purposes. The covered loggia provides plenty of relaxing outdoor spaces and keeps the house cool all year round.

Occupying 120 tarang wah (480 sq. m.) of land, this house on stilts boasts high quality craftsmanship, albeit built on a small budget. This is possible because as much as 90 percent of lumber supplies came from reclaimed wood and other recyclables. New lumber used in the project accounted for only about 10 percent.

The homeowner attributed the success to his sister, who was good at finding recyclable ideas and putting them to good use around the house. This not only saved a lot of money, but it also filled the home with cool pieces of furniture.

Reclaimed wood left over from other projects is used in making a covered gateway separating the serene courtyard and the car park.
The house elevated on concrete piles provides ample multi-use spaces on the open lower floor.

By design, the open lower floor is a feature that makes life less stressful. It provides easy access to practically everything, from the little lake in front of the property, to the peaceful waterway behind it.

It is the area that is used all day every day for relaxation, dining, tending plants and pruning trees in the garden. Plus, correct building orientation ensures the home receives the full benefits of natural ventilation especially during summer months.

The lower floor under the house lies open on all sides.

Originally the homeowners had intended to build a normal two-story house, but later decided to raise it on concrete piles instead. The change of plan resulted in the first floor becoming second, and the old second becoming third.

The main kitchen is on the ground floor. There is a good-sized sitting space with a small kitchen and dining room on the second floor that’s reserved for use in the event the ground floor is flooded. The third floor holds three bedrooms and a Buddha room.

A waterfront piece of ground is used for growing an herb garden. Earthen jars are placed underneath the gutter to harvest rainwater for use when needed.

The exterior walls are inspired by the rice granary in former times, in which vertical studs are installed on the outside and horizontal wood palettes on the inside. The edge joint technique that has existed for a long time ensures the wall is water impermeable during rains.

A minimalist staircase without risers between the treads creates good ventilation and a lightweight look. The same treatment applies to balusters and handrails crafted of steel rods.
A beautiful array of windows opens to take in the view and plenty of fresh air. Narrow window design is used instead of side railing as protection against falling.

On the whole, it’s a beautifully crafted house on stilts, one that fits in perfectly with the peaceful riparian landscape on the outskirts of Bangkok. The interior living spaces are uncluttered in keeping with the minimalist style, while the exterior showcases the architecture, waterfront lifestyles and experiences unique to this part of Central Thailand.
