On a construction site, the difference between a standard result and a truly finished project rarely comes down to the shell of the building. Once the walls are up and the roof is on, it’s the furniture, the windows and the finishing details that decide how a space actually feels to live or work in. That’s exactly where 3LH comes in — the newest of the three companies in the Indo Construction group, founded in 2009 in Phuket.

After years spent coordinating sites for I.C.E. and I.C.P., the pattern was clear: custom furniture and aluminium joinery were too often handed to outside subcontractors — along with the delays and approximations that can come with it. Creating 3LH meant bringing that skill in-house instead of staying dependent on third parties for work that, in the end, shapes much of how a villa, restaurant or office actually turns out.

3LH designs and builds custom furniture sized to the exact dimensions of a space, its use, and the style the client is after. Kitchen fit-outs, built-in wardrobes, bathroom furniture, or more specific pieces for a restaurant or shop — the team works from the real needs of the space rather than offering standardised solutions. This made-to-measure approach makes the most of every square metre, which matters most on projects where space is tight or the architecture brings its own constraints. Materials, timber species and finishes are chosen together with the client, always with the same goal: furniture that lasts and still matches the original brief once it’s installed.

The second pillar at 3LH is manufacturing windows, doors and frames in aluminium. It’s a material particularly suited to Phuket’s climate — far more resistant to humidity and corrosion than many alternatives, while still allowing plenty of design freedom. 3LH builds each piece to measure, working from the exact dimensions of every opening, which guarantees a tight fit and avoids the water infiltration issues that are so common when standard elements get adapted to an existing structure after the fact. On an island where the rainy season tests every piece of joinery, that level of precision tends to make the long-term difference.

Beyond furniture and aluminium joinery, 3LH also handles smaller, one-off jobs: mirror fitting, marble work, repairs and everyday fixes. That versatility means the team can take on a full build or a single isolated request without the client having to find a different contractor for every type of job.

What really sets 3LH apart is its mobile workshop, built to move directly onto the site. Instead of delivering fixed pieces designed far from the project, the team can adjust, refine and build on site, close to the real constraints of the build. That proximity changes the relationship with the client: the last-minute adjustments that are so common in construction become a simple formality instead of a source of delay.

By bringing 3LH into its organisation, the Indo Construction group makes sure no project stops at the building’s shell. From furniture to joinery, finishes to small repairs, the entire last stretch of a project stays in the hands of one team — trained and coordinated to deliver a consistent result, from the first plan to the last detail.
