Week 1: Excavation

We begin by marking out the pool, setting a datum for water level, and then start excavating the swim zone and installing a subterranean drainage system.

Pool Concrete Construction


Week 3: Wall Construction

We construct the swim zone with engineered, reinforced concrete walls and a reinforced concrete raft. A smooth finish on the blockwork and raft is important for our lining finish.

Regeneration zone


Week 5: Regeneration Zone

After backfilling around the swim zone wall, we excavate and profile the regeneration zone and beach and construct the pool edge. We screed the regeneration zone to a smooth finish which allows us to access it for lining.

Week 6: Pool Lining

We install a thick pond fleece to the swim zone and regeneration zone. Then we water proof the pool with a thick flexible liner which is heat welded together to a tailored finish which allows us to use a pool robot for cleaning when the pool is filled.

Deck construction


Week 7: Deck Construction

We construct the deck frame over the filter chamber as we are lining the pool, framing around the pool’s biological filters to allow access hatches to be constructed within the deck.

Week 8: Ground Preparation

After completion of the pool and construction of the decks and walkways, our landscaping team begins work on the wider garden installing steel edges for borders, constructing paths, installing the retaining sleeper walls and paving the wider garden.

Pool Planting


Week 11: Garden Planting

Finally our specialist soft landscaping team moves in to prepare the ground and plant up the garden, lay turf, seeding meadows and plant trees.

Week 12: Pool Planting

After filling the pool we let the clay settle in and absorb water for a couple of weeks then plant up the pool edges with beautiful marginal plants, encapsulating each plant into the softened clay.


Week 14: Wider Garden

Here you can see the landscaping of the wider garden, our soft landscaping team is laying turf and planting up the top garden.

Our Quality & Service Guarantee

Unwavering high standards

We're accredited by the British Association of Landscape Industries (BALI), Association of Professional Landscapers (APL) and the Horticultural Trade Association (HTA) which means we're recognised for continuously meeting the highest industry standards.

Water quality and hygiene

We set the bar high for water quality and hygiene. Utilising world-renowned BIOTOP’s water balancing technology to filter your pool biologically, expect crystal clear water and water hygiene to the German FLL international standard for commercial natural pools.

Quality assurance and commissioning

At each stage of the construction, your pool will be inspected and signed off for quality assurance. Once completed, we commission your pool over a period of time, returning to check plant establishment and water quality. You'll receive a handover with full training in pool maintenance. Each project is completed with an Operations and Design manual and we’re a phone call away should you have any technical questions.


Once we hand over your pool we continue to monitor the water, providing help and aftercare.

We record water tests, monitor plant growth, and maintain pool service data so we understand your pool and water ready to provide professional assistance should you need it.

You’ll also receive reminders for things like turning on the carbonators, starting to fertilise your pool and monitoring plant growth during the summer season.

In addition, you pool will be serviced in winter leaving you with a full service report and water analysis. Some clients enjoy a spring service too, to get their pool ready for the swimming season.
