A light rusting had started before the concrete was placed. The concrete has to be placed before this gets too progressed. Note The vacuum cleaner at the base of the pool. The surface of the pool has to be kept clean of leaves and other debris and the strip footings have to be kept free of dirt otherwise they will not bond with the shell when poured.

The spa showing reinforcing and plumbing. Note 2 suction inlets at the bottom of the pool to comply with safety regulations. Once the plumbing is placed I bent up reinforcing to form the shape of the seat. This is not a structural requirement but helps eliminate shrinkage cracks beteen the seat and shell and gives the concretor a template to guide his concrete placement. I did the same for the concrete steps into the pool.

This Architect Designed Pool in Outer Metropolitan Adelaide was an Owner Builder Project

I drew the plans and provided much of the labor myself, providing a cost saving of around 50%
This Swimming Pool is situated on a hill with a 1 in 3 fall. The site is tiered and over 50 stairs have to be negotiated from the street. Due to the difficulty of site access all materials had to be carried in by hand. The site was also excavated by hand. Provision for a fully enclosed glazed structure around the pool complicated the build by imposing additional structural requirements.
I designed a concrete shell as this could be used as footings for the room over. The structural Engineer advised to found the pool on natural ground.  This advice meant that some structural savings could be made. Instead of having to use piers, a series of strip footings could be used to key the pool into the hillside.  By following this concept the design of the pool became what is known in the industry as a "split level pool." This means that the depth increases from side to side rather than end to end. This has the advantage of giving a fairly continuous depth swimming lane for the entire length of the pool.
There were serious space constraints due to the existing house and garden layout, and an existing sewer easement at the rear of the property that had to be avoided. The room over is still under construction. If you live in Adelaide and are thinking of putting in a pool or pool enclosure - email grantluc@grantlucasarchitect.com.au  I will make sure your pool suits your site and integrates into your garden. An architect designed pool is the difference between a suit off the rack or one tailor made..... and the best bit is that if you have your own plans you can shop around for the best price.
