The pioneer of the net-zero 'Sustainable City' — now building near Muscat.

Diamond Developers

Q: Who is Diamond Developers?

Diamond Developers is a Dubai-based developer founded in 2003 that pioneered the operationally net-zero 'Sustainable City' model. Its first community in Dubailand was the Middle East's first fully operational sustainable community, and the same model now underpins its work in Oman.

Q: What is Diamond Developers building in Oman?

It is building The Sustainable City – Yiti, on the Gulf of Oman coast near Muscat. The project is delivered through SDIC, a joint venture between Diamond Developers and the Oman Tourism Development Company (OMRAN Group), and is Oman's first community committed to net-zero carbon by 2040.

Q: Can foreigners own property at The Sustainable City – Yiti?

Yes. Yiti sits inside an Integrated Tourism Complex (ITC) — the zone type where foreigners can buy freehold, holding full ownership of the home and the land, with the right to sell, lease and pass it to heirs.

Q: What taxes apply to property in Oman?

Oman currently levies no annual property tax and no capital gains tax, and personal income tax is 0% (a 5% income tax on high earners is set for 2028). A one-time stamp duty applies at purchase. This is general information, not tax advice.

Q: What makes the Yiti project 'net-zero'?

The masterplan is built around solar power, recycled and treated water, electric mobility, on-site urban and vertical farming, and recycling, designed so the community can operate at net-zero carbon by 2040 — the same approach proven in Diamond Developers' Dubai community.

Diamond Developers is the Dubai-based firm that pioneered the operationally net-zero 'Sustainable City' model — master-planned communities that pair solar energy, electric mobility, urban farming and circular waste systems with full social infrastructure. Founded in 2003, it delivered the Middle East's first fully operational sustainable community in Dubai's Dubailand. In Oman, it partners with the Oman Tourism Development Company (OMRAN Group) through the joint venture SDIC to build The Sustainable City – Yiti, the country's first community committed to net-zero carbon by 2040.

THE TRACK RECORD

Diamond Developers's record.

Recognised as a regional leader in sustainable urbanism. Its communities are designed to be operationally net-zero: rooftop and carport solar, recycled and treated water, EV-only or low-car streets, on-site urban and vertical farming, and recycling at the heart of daily life — wrapped around schools, clinics, retail and leisure.

Delivery record

Diamond Developers' flagship reference is The Sustainable City in Dubailand — the first fully operational sustainable community in the Middle East — followed by Sharjah Sustainable City (with Shurooq) and further projects. This gives it a working, occupied proof of the net-zero model rather than a concept on paper.

Years active

Over 20 years (since 2003). Multiple 'Sustainable City' communities across the UAE

Financial strength

In Oman, delivery sits inside SDIC — a joint venture with the state-backed OMRAN Group, Oman's tourism-development arm — which aligns the project with Oman Vision 2040 and adds public-sector backing to the build.

WHAT SETS THEM APART

What makes Diamond Developers special.

Property types ApartmentsStudiosVillasServiced residencesHospitality

Price segment Mid to luxury

Signature style

Diamond Developers specialises in operationally net-zero master-planned communities — integrated developments where renewable energy, water recycling, electric mobility and urban farming are built into the masterplan, not added on. In Oman this lands inside an Integrated Tourism Complex (ITC), the zone type that lets foreigners buy freehold.

Payment plans

Off-plan purchases in Oman ITCs are protected by an escrow mechanism: buyer payments go into a regulated escrow account and are released to the developer against verified construction progress. Specific plan terms vary by unit and release at the project level.

THE HONEST VIEW

Strengths & considerations.

Where Diamond Developers shines

A proven net-zero model — an occupied, operational reference community already exists in Dubai
State-backed Oman delivery via the SDIC joint venture with OMRAN Group
Freehold for foreigners inside an ITC, with eligibility for Oman investor residency
Strong sustainability and operating-cost story (solar, recycled water, low utility bills)

Worth considering

A single Oman location (Yiti) — concentrated exposure versus multi-area developers
Yiti is ~30 km from central Muscat — convenient but not city-centre
Still under construction — buyers take on off-plan timing risk (escrow mitigates funds risk)
A relatively new resale and rental market for net-zero stock in Oman
