The five points where your zoning department loses the most time
3Donay was designed around how Turkish zoning actually works in practice; every module answers a real problem from the field.
Physical paperwork ends
DWG, NCZ, GML and PDF files are drag-and-dropped onto a secure cloud infrastructure instead of being hand-delivered on CDs and USB drives.
Process uncertainty disappears
Which stage the project is at, who holds it, what is expected — both the architect and the administration see it live on the same screen.
Phone traffic drops
Automatic SMS and e-mail go out on every status change; "what happened to my project?" calls and visits come to an end.
Revision chaos becomes order
Requested corrections are flagged per file; the architect updates only what is needed with per-file "Replace" or "Add". No version confusion.
Institutional memory is preserved
All review history, notes, file versions and activity logs are archived permanently; the process survives staff turnover.
The process becomes measurable
Approval times, project volume and unit performance reach management as statistics and reports.
From upload to land registry, on one platform
Complete for both sides
Architects and citizens follow the process from their own panel; the municipal team manages everything from a single hub.
Architect / Citizen Side
- Personal panelAll projects, their statuses and recent activity on one screen.
- Multi-file project uploadDWG, NetCAD (NCZ), GML and PDF support; drag-and-drop bulk upload.
- Staged revision flowPer-file "Replace / Add" options update only what is needed.
- Project detail pageReview history, file preview and download.
- Notification centre and messagingCorrespondence with the municipality on the project itself; every notice is on record.
- Announcements and help centreMunicipal announcements and a step-by-step user guide.
- First-run wizardNew users learn the system in minutes with a guided tour.
Municipality / Admin Side
- Admin panelOverview of pending, in-review, approved and rejected projects.
- Review screenFile preview, per-file revision requests, approve/reject with reasoned notes.
- Land-registry tracking moduleSubmission to the registry is tracked on a separate panel; access is role-based.
- User managementRole and permission assignment: admin, review, registry rights and more.
- Statistics, reports and calendarApproval times, project volume, periodic reports and a process calendar.
- Advanced search and announcementsMulti-criteria search across all projects; publish announcements to citizens.
- SMS management and access logsTrack sent SMS; who signed in, when, from where — a full audit trail.
Security worthy of public data
The system has undergone an independent penetration test and logic audit; all findings were remediated.
Enterprise authentication
Enterprise-grade session security with Google Firebase Authentication.
Role-based access
Every user sees only the screens and data they are authorised for.
Session timeout
Idle sessions are closed automatically after a warning.
Server hardening
HTTP security headers, rate limiting and schema-based input validation.
Full audit trail
All sign-ins and critical operations are logged centrally.
Secure file storage
Files live in S3-compatible object storage; every access passes an authorisation check.
Modern, scalable, easy to maintain
| Layer | Technology |
|---|---|
| Frontend | React 19 + TypeScript — modern, mobile-friendly, fully localised user experience |
| Server | Node.js (Express), running 24/7 under PM2 |
| Database | Google Firestore — real-time, auto-scaling |
| File storage | S3-compatible object storage |
| Notifications | SMS provider integration + SMTP e-mail + in-app notification centre |
| Hosting | On your municipality's own domain — e.g. 3donay.yourcity.bel.tr |
Proven in the field, designed around zoning practice
Live reference
Actively used by a municipality; matured on real zoning cases — not a desk demo.
Fits Turkish zoning practice
The revision flow, land-registry process and SMS notifications match how the legislation works in practice.
One end-to-end platform
Upload → review → revision → approval → registry tracking; no extra software or mandatory integrations.
Fast adoption
A fully localised interface and first-run wizard keep staff training to a minimum.
