Rooms that let the air back in.
We renovate terrace houses, condos and small shops for heat, rain and real family life. Deep shade first, cross breeze second, then terrazzo and timber you want to touch.
How we think about a room
Our houses were built for shade and moving air. Then we sealed them with glass, glossy tiles and air-cond. Rongga puts the old sense back: roster walls that breathe, eaves that keep rain off the window, floors that stay cool under bare feet.

Four ways in.
Most clients start with a renovation and come back for the shop. Every service runs on the same drawings, the same weekly report and the same site lead.
Renovation
Kitchens, bathrooms, whole floors. We draw it, price it line by line, then run the site.
Commercial fit-out
Cafés, clinics-to-be, studios and shops. Built around your licence dates and opening day.
Design-and-build
One contract, one team, one price. Design, permits, trades and handover under our name.
3D visualisation
Photoreal views and a walkthrough of your room before a single tile is bought.

Client words (fictional, demo)
"We stopped running the air-cond in the afternoon. The house just stays cool now, and the kids do homework on the terrazzo."
"They opened our café on the date printed on the licence. Nobody else would promise that."
"The Friday reports had photos of every wall before it was closed up. I keep them for the next owner."

Permits, weeks, money.
The six questions we answer on almost every first call.
Do I need a permit to renovate?
Usually, yes. Most councils (MBPJ, DBKL, MBSA) want a renovation permit for hacking, wet works or anything outside. Condos also need management approval. We prepare and submit both. Structural changes or extensions need a submission by a registered architect or engineer, which we coordinate with partners.
How long does a terrace house take?
A Rework of an 1,800 sf terrace runs about 20 weeks from site visit to keys: 8 weeks of design and approvals, 10 to 12 weeks on site. Permits are the part we cannot rush.
Can we live in the house during works?
For a Refresh, often yes, room by room. For a Rework we strongly suggest moving out: dust, water cuts and power cuts are part of hacking.
How do payments work?
Design fee in two parts (start, and sign-off of drawings). Build in five progress claims tied to work you can see on site, never ahead of it. 5% is held until the defects period ends.
Are you architects?
No. We are an interior design studio. The word architect is reserved by law for persons registered with LAM, and we work with registered architects and engineers whenever a job needs one.
What if something cracks after handover?
We fix defects caused by our work for six months at no charge, and our carpentry has a two-year warranty on hinges, runners and carcasses.
