Software for architecture,
engineering, and
construction.
PT Holixora Digital Technology builds Cetharia and the systems around it for design and build firms. From drafting and rendering to BOQ and clash detection, we deliver software shaped around how a studio actually works.
Three ways we work with design and build firms
Whichever model fits, we stay end-to-end owners of the work, with you in control of direction.
Off-the-shelf product
Cetharia, our platform for drawing, visualizing, costing, and clash-checking. Subscribe per team, active within days, no installation, just a browser.
Studios use Cetharia directly for CAD drafting, AI rendering, BOQ, and clash detection.
Custom software development
Internal systems for studios and contractors: project management, administration, and reporting. Drawing computation matched to your office's own standards, integrated with tools your team already uses.
Built internal project and BOQ tooling shaped around an existing studio workflow.
White-label partnership
Our product runs under your brand and your working rules. Scope and phases are agreed together, with development-cost or revenue-share terms.
The model Lumbung Architect and Teras Rumah Studio use today.
How we work
From first conversation to running results, in four steps.
First conversation
We hear the problem, and look at the files and workflow your team uses today.
Scope and proposal
Deliverables, phases, and cost are written down clearly before any work starts.
Staged delivery
Work is shown to you in phases, so it can be corrected early, not at the end.
Handover and warranty
A short training for your team, then a warranty period once the handover is done.
Standard terms for project engagements: 30% upfront, 50% at the main phase, 20% after handover. Part of the payment is held until the warranty period ends.
Proof: from Griya Studio to Cetharia.
We shipped Griya Studio, an AI BOQ and rendering platform, in 30 days and grew it to 63 registered users and 553+ renders processed. That engine is now part of Cetharia, our current platform, alongside CAD drafting and clash detection.
