Residential
Our reference list includes 71 residential projects, and the SECCO group has its own condominium specialist, Grand Intersec.
Condominiums from Bangkok to Phuket
Our 71 residential projects are mostly condominium towers and serviced apartments. 42 of them are Supalai developments, from Supalai Park and Supalai Lite towers in Bangkok to Supalai Mare Pattaya and Supalai Vista Phuket.
Most are in the Bangkok area, with others in Sriracha, Rayong, Pattaya, Phuket, Hat Yai and Chiang Mai. Three are on site now: Laguna Beachside and Laguna Seaside Residences in Phuket, and Niche Mono Bangpo in Bangkok.
Our EPC service includes mechanical and electrical design for condominiums, and our civil and architectural construction references include high-rise condominiums as well as hotels and factories.

More about the SECCO groupWhat a residential tower asks of its systems
People live in these buildings around the clock, and each home has its own supply, meter and air conditioning. These are the demands that shape their engineering.
Water to every floor
A tall tower stores water, pumps it up in pressure zones and drains it down again, day and night.
- Storage tanks, booster pumps and pressure-reducing stations
- Cold water, and often hot water, to every unit
- Sanitary drainage and waste water treatment before discharge
- Swimming pools and water features for shared amenities
Cooling, unit by unit
Most condominium units have their own air conditioners, so the building carries pipework, drains and power for hundreds of separate systems.
- Split-type or VRV systems for each unit
- Condensate drainage and space for outdoor units
- Ventilation for corridors, car parks and refuse rooms
Power, metering and connectivity
Every unit needs its own supply and meter, and residents expect TV, telephone and data to work on the day they move in.
- Transformers and main switchboards for the whole tower
- Separate electricity metering for each unit
- TV, telephone and data outlets
- Access control and CCTV for shared areas
Fire safety where people sleep
Residents may be asleep when a fire starts, so early warning and clear escape routes are essential.
- Fire alarm and detection in units and common areas
- Sprinklers and fire hose cabinets
- Pressurised escape stairs and emergency lighting
- Standby power for fire pumps and fire lifts
