How to read GFA, plot ratio and building rights on a Dubai plot

Two plots of the same size, four hundred metres apart, can differ in price by a factor of three. Buyers new to land assume the gap is location. Usually it is building rights: how much floor area the authorities will let you construct, and in what form. Once you can read that, plot pricing stops looking arbitrary.

The three numbers on an affection plan

Every Dubai plot has an affection plan issued by Dubai Municipality. It carries the plot number, the land use and the development controls. Three figures drive everything.

Plot area is the land itself. It appears in square metres on the deed and is almost always quoted in square feet in the market.

Plot ratio, also written FAR or floor area ratio, is the multiplier applied to plot area to give the permitted built area. A ratio of 1.2 on a 10,000 sq ft plot permits 12,000 sq ft of construction.

GFA, gross floor area, is the result. It is the total floor area you may build, counted across all storeys. It is the quantity a developer buys, and everything else constrains how that GFA is arranged.

G+N notation

Alongside the ratio, the plan states the permitted massing in the local shorthand:

• G. Ground floor only.
• G+1. Ground plus one upper floor. This is the standard villa-plot right in Jebel Ali Hills, Al Furjan and Dubai South.
• G+1+basement. A basement is excluded from GFA in most zones, so the allowance is worth chasing.
• G+2. Ground plus two. In several Dubailand pockets it also permits multiple dwellings on one plot.
• G+4. The typical low-rise commercial or residential envelope in Majan, Arjan and Jumeirah Village.
• G+P+N. A podium level for parking sits between the ground floor and the tower floors.
• Unlimited. No stated height or GFA cap, applied on parts of the Sheikh Zayed Road corridor and in DIFC. In practice the envelope is then set by aviation height clearance and civil defence access. What the authority approves on the massing study decides the rest.

Height and ratio are separate controls, and both bind. A G+4 right on a plot ratio of 2.0 may not give you five full plates. The ratio can run out at the third.

Setbacks, coverage and the difference between GFA and a building

GFA tells you how much you may build. It does not tell you what shape the building takes. The affection plan also fixes setbacks from each boundary and a maximum ground coverage. On residential plots that coverage is commonly forty to sixty per cent. On a narrow parcel, setbacks can make the theoretical GFA physically unbuildable. You run out of footprint before you run out of allowance.

Corner plots price at a premium for more than light and access. Two street frontages usually mean a friendlier setback geometry and a more efficient footprint.

What is normally excluded from GFA

Rules vary by zone and should be confirmed against the plan. The common exclusions are basements used for parking or services, covered parking at ground level, plant rooms and lift machinery. Shaded terraces are also excluded up to a stated proportion. Balconies are frequently counted at fifty per cent. Each exclusion is saleable area you get without spending GFA, so it belongs in the appraisal.

Turning rights into a price

The developer's arithmetic runs backwards from the finished product.

1. Take the permitted GFA and apply an efficiency factor to get net saleable area. Residential schemes typically run at 80 to 85 per cent, and a tower with a large core runs lower.
2. Apply the achievable rate per square foot for finished product in that community.
3. Deduct construction cost, consultants, DLD and authority fees, finance, and a developer margin of fifteen to twenty per cent.
4. What remains is the residual land value.

Run that on two plots and the price gap explains itself. A 10,000 sq ft plot at G+1 with a 1.2 ratio yields 12,000 sq ft of GFA. The same plot at G+4 with a ratio of 2.5 yields 25,000 sq ft. The land has not moved, and the product on it has doubled.

Questions to ask before you sign

• What is the current affection plan date, and has the zoning been amended since?
• Is the stated GFA granted, or indicative pending a massing submission?
• Are basement and covered parking excluded from the GFA count in this zone?
• What are the setbacks on each boundary, and what footprint do they leave?
• Is there an approved concept or a stamped drawing set transferring with the land?

That last question is not paperwork. A plot with ready drawings and an approved concept removes months from the programme. In a market where finance is priced monthly, that time has a number attached to it.
