Upper-floor, rooftop and precast pools

Pools above the ground

On an upper floor or a rooftop, the pool, its water and its finishes all sit on the building. We plan the pool around what the structure can carry. Early on, we also plan the waterproofing, space for the overflow and balance tank, drainage and access for equipment. On an existing building, we start by reviewing the drawings and the structure with the engineer.

• Rooftop and terrace pools on new and existing buildings
• Pools on the upper floors of villas, condominiums and hotels
• Cantilevered pools that project beyond the supporting structure
• Pump rooms on upper floors, close to the pool they serve

Lightweight and precast structures and elements

Where weight or site access matters, lighter structures and precast elements help. Precast parts are made to shape in advance and set in place on site, so there is less wet work at height and in tight spaces.

• Precast coping, including slabs that sit over an overflow channel
• Precast steps and benches
• Precast wall and edge panels
• Lightweight shell options, agreed with the engineer for the individual project

Design and engineering

We design the pool itself: the concept, sketches, 3D views and renders, the hydraulics and the equipment sizing, as described on our Pool design page. When a pump room sits on an upper floor or above water level, the hydraulics are calculated for that height. We work on structural decisions with you and your engineer — or, if you don't have one, with our licensed partner engineer, who prepares and signs the shell calculations, reinforcement details and permit drawings.

Waterproofing and services

A leak from a raised pool shows in the rooms below, so we plan the waterproofing with the structure rather than add it at the end. Waterproofing is one of our main areas of work, and we cover the roofs and terraces around the pool as well. Leak finding includes pipework pressure tests and water-level checks with the pump on and off, though we cannot promise to find every leak. Electrical work for pumps and lights, including isolation, earthing and earth-leakage checks, is carried out by a licensed electrician agreed with the owner.

What to send for a first discussion

For a first discussion, send us:

• Drawings or photos of the building and the place where the pool will sit
• The property location in Phuket or elsewhere in Thailand
• The pool size and shape you have in mind, and whether it is a new pool or an existing one to renovate
• Any structural drawings or reports you already have
