A cherished property in North Jakarta’s, premier waterfront enclave, faced a looming threat: land subsidence fueled by excessive groundwater use. The owner turned to K-Thengono Design Studio for a solution to revitalize and protect their home. The task was to design an elevated sanctuary that harmoniously blended luxurious living with robust resilience, enhancing the home’s connection to the waterfront whilst fulfilling the homeowner’s desire for a penthouse-esque experience.

Building a foundation for the future means addressing imminent challenges head-on. For the owner of this remarkable house, the alarming news of Jakarta sinking, especially in the northern part of the city, was a call to action. They sought to turn this challenge into an opportunity to create a well-designed, aesthetically pleasing home that was also prepared for the future.
“With the building site sitting 0.7 metres below sea level and projections indicating a further three-metre descent by 2041, a strategic approach was crucial to ensuring the residence’s longevity and stability,” explained Kelvin Thengono, the lead designer.
A pile-slab foundation was utilized to bear the structure’s load and secure the residence’s structural integrity amidst ground shifting. In addition, a 4.5-metre-high dike was constructed along the rear of the property facing the canal, safeguarding the home against potential coastal flooding for decades. The plumbing and electrical systems were strategically installed underground and attached to the foundation to minimise damage from future land subsidence.
Elevating the Living Experience
Living areas were cleverly elevated on sleek, black V-shaped stilts to maximise views and create a flood-proof space. This ingenious design preserves clean aesthetics by minimising the number of columns, hence ensuring panoramic ocean vistas.
“The layout was tailored to the homeowner’s lifestyle. The raised ground floor, now at a safe height of 3.3 metres above the original terrain, accommodates parking and service areas,” affirmed the lead designer.
One level up reveals a communal area with a refreshing pool, ideal for socialising and relaxation. In contrast, the third level houses a private sanctuary, offering serene bedrooms with captivating sea views. Crowning the residence is a multipurpose space with a spacious balcony overlooking the canal.
A Seamless Blend with Nature
Sustainability shapes the design, with each floor positioned to optimise natural light and minimise reliance on artificial cooling. Kelvin explained that the second-floor workspace, for example, is placed under a cantilevered volume that blocks harsh east-west sunlight. Similarly, the living room’s orientation towards the neighbouring park shields it from the intense afternoon heat.
“Materials were deliberately chosen for their durability, minimising maintenance needs. Furthermore, a rainwater harvesting system collects and distributes rainwater for landscape irrigation, showcasing the commitment to this house’s eco-friendly design,” Kelvin disclosed.
Coastal-adaptive, low-maintenance, and edible plants line the expansive outdoor area. Strategically placed throughout, these plants also serve as natural windbreaks against sea breezes. Beyond the edible garden, the outdoor space includes a designated dry area for the homeowner’s pets, whilst a terrace offers an ideal setting for yoga sessions or barbecues. This terrace leads to a private pier, completing a seamless transition between indoor and outdoor living.
By harmoniously integrating the sea and land, K-Thengono Design Studio has crafted a home that defies the challenges of a sinking coastline. The result is an environmentally conscious and resilient haven offering the luxury of nature, privacy, and peace of mind amidst an ever-changing environment.
