Fixed-price villa extension for The Sustainable City homes — from AED 120,000. Diamond Developers community approvals handled in-house. Free 3D design. 3-year warranty across 800+ Dubai projects.
Quick Answer · The Sustainable City
A villa extension in The Sustainable City costs AED 120,000–280,000 for a single room, AED 280,000–600,000 for a full ground-floor extension, and AED 600,000+ for an additional storey. Every extension needs a The Sustainable City community NOC plus a Dubai building permit and stamped structural drawings, all handled in-house. Timelines run 8 weeks to 8 months. Fixed price, 3-year structural warranty.
After 800+ Dubai projects we see the same problems in The Sustainable City again and again. Here's what goes wrong — and how we fix every one.
Most The Sustainable City plots have room to extend. We unlock the extra majlis, bedroom or open-plan living you need without moving home.
Set-back, height and coverage rules differ by community. We design to The Sustainable City's exact rules so the permit passes first time.
A bad extension shows where old meets new. We engineer movement joints, tie reinforcement and waterproofing so the addition is seamless and dry.
Nothing devalues a villa like a mismatched extension. We match render, roof, glazing and proportion exactly to the original.
