The Harmony by Wallaya Villasvillas in Si Sunthon, Phuket

The Harmony by Wallaya Villas is a pool-villa development by Wallaya Villas Development Co., Ltd. in Si Sunthon, Thalang district, Phuket. The architecture is tropical contemporary, with open-plan interiors built around natural light. The villas were handed over in the second quarter of 2026.

The project comes in only two fixed sizes: three-bedroom villas at exactly 272 m² and five-bedroom villas at exactly 897 m², more than three times larger. There is nothing in between — a buyer chooses either a compact family villa or a large residence built for guests and staff.

If you are going to live here

The three-bedroom villas get a rooftop terrace and jacuzzi, the five-bedroom ones a private pool, pool deck and dedicated work and leisure areas. Everyday infrastructure is not within walking distance: Ban Liphon School, Life School Phuket and Thanyapura medical center sit 2.2–2.3 km away, and Porto de Phuket mall is 2.25 km out. Si Sunthon is still an area filling in, not a settled neighbourhood with amenities at the door.

If you are buying to let

The developer states no in-house management or rental programme — only general language about rental potential. The villa format is family-sized, with none of the compact units that nightly income depends on, so this suits a long family tenancy rather than a tourist turnover, and arranging management is left to the buyer.

If you are holding for capital growth

The project is already handed over, so the construction-stage gain is fully taken for anyone buying now. Supply comes in exactly two rigid sizes with nothing between them, and the area around Si Sunthon is still maturing — how liquid the large five-bedroom residence proves on resale will depend on how quickly that infrastructure fills in.
