Drawings & approvals
Issue sets, track revisions, collect client sign-off with a timestamp.
■ For design-build architecture firms
Run every home you design, from first sketch to handover.
Plinth keeps your drawings, estimates, site progress, vendor orders and client approvals in one place. Your studio and your site work from the same information, and your clients always know where their home stands.

Why firms switch
Designing the home is the easy part. Keeping studio, site and client in step is where projects slip.
Site builds from last week's drawing
One live drawing register
Every sheet, revision and approval in one place. Site engineers always open the current issue, and superseded sheets are marked so nobody builds from them.
Estimate and actual cost drift apart
BOQ connected to purchase orders
Raise vendor orders straight from your BOQ. See committed versus estimated cost for every item and every project before it becomes a margin problem.
Clients call every day for updates
A client portal they actually use
Clients see dated site photos, approve drawings and material choices, and track payment milestones on their phone. Fewer calls, faster decisions.
Billing milestones get missed
Stage-linked invoicing
When the site team marks plinth, slab or finishing complete, the matching invoice is ready to send. Cash flow follows progress instead of chasing it.
The platform

From practising architects
What design-build firms say after the pilot.
Sample testimonials · replace before launch
"We used to send drawings over three different chat groups. Now the site team opens the register and builds from the right revision. Rework on our last two villas dropped noticeably."
"Our clients approve finishes in the portal instead of over the phone. Decisions that took a week now take a day, and we have a record of every one."
"Seeing BOQ against purchase orders for every project changed how we price. We caught a steel overrun before it hit our margin."
Questions
Common questions before a demo.
More answers on the full FAQ page, or ask us directly on WhatsApp.
Who is Plinth built for?
Architecture firms that design homes and also take responsibility for building them, whether as design-build, turnkey or design plus project management. It suits studios from 3 to about 60 people running several residential sites at once.
Does it replace AutoCAD, Revit or SketchUp?
No. You keep designing in your usual tools. Plinth manages what happens after: issuing drawings, approvals, estimates, procurement and site execution. You upload PDF and DWG exports.
What happens in the free demo?
A 30-minute video call. We ask how your projects run today, show the platform on a sample villa project, and outline what a pilot would look like for your firm. There's no obligation.
How is pricing structured?
Plans are priced per firm based on team size and number of live projects, billed monthly or annually. We share exact pricing after the demo once we understand your setup.
Can my site engineers use it on their phones?
Yes. Site progress, photos and snag lists are built for phones and work on patchy connections, syncing once the signal returns.
