Fourteen years of building things that were designed to be built.

We started in 2012 as a two-person architecture practice working out of a shophouse in Kemang, taking on small residential renovations because that's what walked through the door. What we noticed early was that the projects that went smoothly weren't the ones with the most ambitious designs — they were the ones where the structural engineer and the contractor were in the room from week one, not brought in after the drawings were finished.

That observation became the studio's structure. Today, TongDSK runs architectural design, structural engineering and construction management as one coordinated practice rather than three separate handoffs. The same team that draws your floor plan also checks whether your contractor's quote for the foundation actually matches the soil report.

We work across Indonesia, from single-family houses on narrow urban lots to community pavilions, adaptive reuse of old industrial buildings, and mid-scale commercial fit-outs. The scale changes; the process doesn't. Every project starts with a site visit and an honest budget conversation, not a rendering.

We're a team of twenty-eight — architects, structural engineers, interior designers and site supervisors — organized into small project teams so that the person who designed your building is still the person answering your calls once construction starts.
