Lilu Natural Swimming Pool

Hybrid Architecture for Aquatic Facility

The 1000 m2 aquatic complex includes a swimming pool, a hamman, a health club, and an organic cafe. It is an attractive and easily accessible center dedicated to bathing, swimming, and exercising, with flexible hours. It is also a place to relax and socialize with friends to meet for informal meals and healthy snacks, play, and sun bathe.
Ancillary sports amenities adjoin the aquatic complex and encourage diverse sport practices and games in the middle of the rural park (football and handball fields with tennis courts, jogging, strolling, basketball).
The 300 m2 swimming pool basin is filled with natural recycled water. The rainwater coming down from the olive orchard hill, the roofs of the collective housing pavilions and other facilities is harvested, filtered, then purified by plants. This recycling process establishes an active dialogue between residents and local eco-system enriched by a newly introduced bio-diversity whose role is to ensure the upkeep of a low maintenance, self-sustainable rural park, natural pool and botanical garden. The pool construction materials are local rocks, gravel, field stones and larger demolition stones recovered from on site existing ruins. Construction does not necessitate concrete.
The 540 m3 basin is filled with filtered rain water requiring no chemical addition but only natural plants cultivated within the pool. Water is naturally cleaned by two types of plants through a purification and oxygenation processes then recycled and reinstated through a low energy consumption adjustable pump.
The vaults will be erected by local masons using local materials. The roof is composed of three vaults. The main one spans the basin’s total length. The two smaller ones shelter lateral sides from adverse weather conditions. The Vaults parametric design and digital fabrication involve the use of RhinoVAULT software. It is a structural form using the Thrust-Network-Approach to intuitively create and explore compression-only structures.
