A place to learn architecture and engineering for students, juniors and firms in Indonesia. Lessons are short, practice uses drawings you can actually change, and the teachers are practitioners who run their own classes as creators.

Start with the Beginner courses. The Reading Working Drawings and Building Science tracks have no prerequisites. You don't need to have visited a project to follow the first chapter.

Chapter 1 of every course, daily practice, the Glossary and Liga Studio. No card, and no ads.

Three to eight minutes. Enough for one train ride or the gap before a morning meeting. Ten minutes every day beats three hours on a weekend.

Here you do the work, not just watch. You stack the layers of a detail, find the fault in a drawing, and slide a parameter until the drawing changes. Video is there when it helps, but it isn't the point.

Arvy is the tutor at Detarva Academy. With Tanya Arvy you can ask about a lesson, and Arvy helps you find the relevant material and sources. Technical decisions on a project stay with you and your senior.

No. Every detail in the courses is an illustration for learning, not for construction. For a real building, follow your firm's standards and the project engineer's drawings. If an existing building has a problem, ask an expert who can see it in person.

Pro at Rp149.000 a month opens every course, track, exam and certificate while you subscribe. Single course starts at Rp199.000, priced by its creator, and is one payment for one course, and that course stays yours. Track exams and certificates come with Pro, Team and Firm.

Yearly is Rp1.188.000, which works out to Rp99.000 a month. That saves 34 percent over paying monthly.

Yes. A monthly subscription stops at the end of the period you've paid for. Certificates you've earned stay yours, and your progress is still there if you come back.

Checkout on this site is a simulation: you go through the same steps as a normal purchase, but no money moves and no card is charged.

Try chapter 1 before you pay. If you've already paid, the refund policy sets out what happens.

Team is Rp119.000 per seat per month, minimum 5 seats: everything in Pro plus the seat dashboard, cohorts and reports. Firm is Rp169.000 per seat per month, minimum 15 seats: plus firm standards as private tracks. Both are billed yearly.

A skill track covers one subject end to end, such as Core Details, and closes with an exam and a certificate. A career track pulls courses from several subjects in the order one role needs them, such as Studio-Ready Drafter.

40 questions in 60 minutes: multiple choice, calculations and reading drawings. You pass at 75 percent. The clock keeps running once you start, so set aside a quiet hour.

You can retake it after 7 days. Your results show which parts are weak, so use the time to redo those chapters.

It's proof you passed a Detarva Academy track exam. It isn't a professional competency certificate or a licence to practise. Many people use it in their portfolio when applying, and how much it counts is up to the employer.

Yes. Each certificate has its own number and can be downloaded as a PDF or shared through a link.

Team starts at 5 seats and Firm at 15. Below that, Pro per person usually makes more sense.

Active seats, tracks in progress, progress per person, exam scores and exercises marked Needs revision. Private conversations with Arvy are not visible.

Firm standards live in Detarva as reviewed details. The curriculum team turns them into lessons and exercises, so juniors learn from the firm's own details rather than generic examples.

Only seats in your firm. Private tracks don't appear in the public catalog and aren't used for other courses.

The seat returns to the firm and can be reassigned from the dashboard. Any certificates that person earned stay theirs.

70 percent of what your courses earn. Single-course sales are counted per transaction. Pro revenue is split by minutes learned in your courses, and 70 percent of that is yours. You can see the breakdown per course every month.

You do. Set each course's single price between Rp99.000 and Rp999.000 in Creator Studio, and 70 percent of it is yours. Your course stays open to Pro learners.

It stays yours. You license it to Detarva Academy for as long as we work together. Your videos, notes and drawings don't change hands.

Yes. The arrangement isn't exclusive. Your online classes, bootcamps and community keep running as usual.

For a five-chapter course, plan on two to three days of recording and a few hours of review. The curriculum team builds the interactive practice, questions and translation with you. If you already have class material, much of it can be reused.

On the 25th of each month for the month before, with a report per course.

Give 30 days' notice. Your course stops being sold after that. Learners who already bought it keep access, and your share of past sales is still paid.

No. Income depends on your topic, the quality of the course and how actively you bring your audience. The numbers on this page are illustrations of how the maths works.

Only you, unless you're on a firm seat. On a firm seat the principal sees progress and scores, not your conversations.
