Union station: the average passed, the blocks didn't

Case study · Union metro station, Deira · measured 11 November 2026

The question

If a station area's average density already clears a target, is there still room to grow, and where?

The place and the method

The built urban blocks within a 10-minute walk of Union metro station's exits in Deira, Dubai, along the streets, measured in OSMosis's Room to grow on 11 November 2026, inside a 1.5 km study area.

What was measured

Measure	Union station, 10-minute walk
Built urban blocks read	39
Floor area in those blocks	2.66 million m²
Average floor space index of the blocks	3.4 (2.85 with the station's own 26 ha block)
Target used for illustration, every block	2.5
Blocks short of the target	11 of 39
Floor those blocks lack, together	about 190,000 m²
Share of that gap in five blocks	89%

What it shows

The average clears the target easily. The 39 built blocks hold 2.66 million m² of floor, an average floor space index of 3.4 against an illustrative target of 2.5.

Eleven blocks don't. 11 of the 39 blocks fall short of 2.5 and together lack about 190,000 m² of floor.

The gap is concentrated. Five blocks hold 89% of it: those are the places to look first.

An average hides where change would happen. Read block by block, a station area that passes on average still shows where intensification would actually occur.

What it means for planning

Screen station areas block by block before setting zone-wide targets.
Use the walk from the station's exits along the streets, not a circle, to decide which blocks belong to a station area.
Dubai's TOD Manual sets indicative minimum floor-area ratios of 1.75 to 4.0 for whole station zones, by centre type and distance: they apply to zones, not to single blocks.

Limits

Blocks, not plots: parks, civic land, street land and the station's own 26 ha block are left out; with that block the average is 2.85, still above 2.5.
About half the floor area uses estimated heights, so every block needs a check by eye.
The single 2.5 target is for illustration; it is not a planning requirement.

Questions

How much room to grow is there around Union metro station in Dubai?

Read against an illustrative floor space index of 2.5, 11 of the 39 built blocks within a 10-minute walk of Union station fell short, together by about 190,000 m² of floor, five blocks holding 89% of it (measured 11 November 2026). The average of all blocks, 3.4, already cleared 2.5.

Can I read the development potential around a metro station?

Yes: OSMosis Room to grow reads every block within a 5, 10 or 15-minute walk of a station against a target floor space index you choose, or the place's own published figure where there is one.

The same readings can be made for any place in OSMosis: see how.
