Render vs reality

We build what we promise.

Every client approves a 3D render before we start. Drag the line to compare it with the finished house, photographed from the same spot.

FAQ

Questions homeowners ask first.

Can't find yours? Message us and we'll answer it.

Ask on WhatsApp
Is the price really fixed?

Yes. After the site survey and design you sign one contract at one fixed price for the agreed scope. The price only changes if you change the scope, and every change is quoted in writing before work starts.

How long does building a house take?

Most two-story homes take 8 to 12 months of construction after permits, depending on size and finish level. The estimator above gives a first indication, and your detailed schedule comes with your quote.

Do you handle permits (PBG)?

Yes. We prepare the drawings and structural calculations and manage the PBG application for you as part of the contract.

Can I see progress if I live in another city?

Yes. Your client dashboard has weekly photo and video updates, a live progress percentage, your payment schedule and a direct chat with your project manager.

What warranty do you give?

Every build comes with a 10-year structural warranty, plus aftercare support after handover.

Do you work outside Jabodetabek?

We build in Jabodetabek, Bandung and Bali. If your land is elsewhere, message us and we will tell you honestly whether we can serve your site well.
