Sobha Sienna Master Plan
Sobha Sienna Master Plan is designed across 8.5 acres at Egattur on Old Mahabalipuram Road (OMR), Chennai, with three towers of B+G+32 and 650 apartments set among landscaped open spaces and shared facilities. This makes it a well-planned gated community on OMR.
Sobha Sienna Master Plan Overview
The Sobha Sienna layout shows a premium residential community of 650 homes in 3 BHK and 4 BHK configurations. It is developed by Sobha Limited and planned across 8.5 acres at Egattur on OMR.
Three towers rise from a B+G+32 profile. This keeps the built footprint compact and leaves the rest of the site open for gardens, a grand clubhouse and community spaces.

What the Sobha Sienna Master Plan Shows
A master plan explains how the whole community is organised. It shows where each tower stands and how vehicles move through the site.
For a 32-storey development on 8.5 acres, these choices shape daylight, privacy and outlook for every home. The plan shows:
- The location of each of the three towers
- Entry and exit points
- Internal driveways and vehicular circulation
- Basement parking and service areas
- Landscaped open spaces and gardens
- The clubhouse and amenity zones
- The direction and orientation of homes
This helps buyers understand the community before they choose a tower and a floor.
Tower arrangement and open spaces
The Sobha Sienna tower plan has three high-rise residential towers. Each follows a B+G+32 structure, with one basement level, a ground floor and 32 upper floors. The 650 apartments are shared across the three towers.
Building tall rather than wide frees the ground. With the footprint concentrated in three towers, more of the 8.5 acres goes to landscaped gardens, open spaces and common facilities.
- Three towers: a compact cluster of high-rise homes.
- B+G+32 profile: one basement, ground and 32 upper floors in each tower.
- 650 apartments: shared across the three towers.
- Open ground level: parking is planned so that the ground stays pedestrian-friendly.
Tower names, per-tower unit counts, core layouts and lift details are part of the layout shared on request. This makes it easy to compare towers before you choose a home.
Tower spacing: the distance between the three towers, and their orientation, shapes the daylight and privacy each apartment gets.
Which side your home faces: on a corridor site, a home facing OMR and a home facing inward offer a different outlook and feel. The plan lets you pick the view that suits you.
Clubhouse and amenity zones
The Sobha Sienna clubhouse is the social heart of the layout. Outdoor zones for active, leisure and family living sit around it.
- Grand clubhouse: a multi-level hub for fitness, social events and recreation.
- Resort-style pools: swimming areas for relaxation and laps.
- Wellness and fitness: indoor fitness facilities and wellness zones.
- Indoor sports arena: a climate-controlled space for indoor games.
- Social spaces: areas for community gatherings and celebrations.
Outdoor living across 8.5 acres adds more choice:
- Active living: sports courts and outdoor fitness areas.
- Leisure living: landscaped gardens and open spaces for quiet time.
- Family living: family and kids’ recreation and community spaces for all age groups.
The position of the clubhouse and amenity zones helps you balance convenience and quiet. Some buyers prefer to be close to the action, while others prefer calm. The complete list is on the amenities page.
