Century Regalia features a robust infrastructure with an RCC framed building structural system that complies with Seismic Zone II standards, using concrete solid block masonry for both exterior and interior walls where applicable. The apartments are adorned with imported marble flooring in the foyer, living room, dining room, and all bedrooms, while vitrified tiles are used in the kitchen, washrooms, utility areas, balcony, servant room, and servant washroom.

The doors are crafted from engineered wood for both entrance and internal doors, and the balconies, ventilations, and windows are equipped with UPVC or anodized aluminum sliding doors with glass and mosquito mesh. In the kitchen and utility areas, electrical provisions include 4 sockets of 16 AMP and 4 sockets of 6 AMP, along with plumbing points that include two water supply points in the utility and one in the kitchen, as well as a drainage point provision in the utility.

Security is a priority, with a biometric lock on the main door, video phone, ANPR solution, EV charging station, retina or biometric scanner for staff, smart common lockers, and 24-hour CCTV surveillance. The electrical setup includes split AC units, smart switches compatible with home automation, and ample power supply—8 KW for 3 BHK units and 10 KW for 4 BHK units, with corresponding power backup of 4 KW and 5 KW respectively.

The painting work features acrylic emulsion paint for interior walls, ceilings, kitchens, and utility areas, weatherproof texture paint for exterior walls, and cement paint above false ceilings in toilets. The bathrooms and kitchen are equipped with high-quality sanitary fittings and faucets from brands like Kohler or TOTO, along with shower partitions and branded exhaust fans in all toilets.
