Quarry sand was used under the pavers between the pool and the house. This shows the service run for the solar hot water between the pool and the house. I used recycled cement paving on edge and sections of stormwater pipe as inspection points at all of joints in my pipework so visual inspection would be possible at a later date if I had a leak

The existing monolithic paving around the house was removed between the pool and the house to reduce the feeling of clutter and make the space cohesive. Note I recycled these pieces of concrete by standing them on edge, forming a small retaining wall (the pool is 1 step below the patio) which also provided  point to mortar the edges of the new concrete pavers to. Note the 50mm space between the pool edge and the concrete. The formboards had bowed in and the pool edge was not straight. The coping tiles will hide this.
The existing monolit...
Solar pipes between the house and pool. One up to the roof and one back from the roof plus a conduit for a 12 volt temperature sensor cable. Note I have cut away the existing cement paving around the house to provide easy cable access. The finished unit paving level is to be one step below the existing monolithic paving level. This fixes a fault with the existing house where the existing paving was above the damp-course.

Paving almost finished. Cuts were left until last to save on machine hire time. I hired a large table brick saw and did all the cuts in one day

Note The bullnose edge for the pavers in the foreground. This is to be inside the pool room enclosure and so will become a step. The pavers beyond will be outside the room and therefore needed no special edge treatment.

I finished off the edge of the cut concrete with 75mm of new concrete and tooled in grooves to match the existing stairs. To ensure the new and old stuck together properly I used steel dowels and 3 coats of Chemstick to the existing face

One of the column baseplates in position. Note the cantelever on the baseplate due to the pool edge not being in the correct position. Additional monolithic concrete was poured under after the baseplates bolts were epoxied into position. Hilti HAS HVU system epoxy system with stainless steel holddown bolts were used as seen in background. The baseplate had megapoxy H mixed with sand to form a flowable grout placed under it.

This hammer drill and 20mm masonry bit from bunnings did a great job. Together they cost $100.

I had to place an acrylic skim coat over the concrete shell as a prep for the plasterers. This keys the Qpebble to the shell and provides an constant substrate so the Qpebble colour does not look patchy. Thoroughly wetting the shell down is a requirement to get the skim coat to set properly. I applied a broom finish with a bannister brush.
I had to place an ac...
Formwork for the hob in the background. This was tricky due to the fact the outside board was 2.5m above the ground. Note that on this side of the pool the hob is formed in 3 separate pieces as I had to leave spaces at the column baseplates.
Formwork for the hob...
My plan included a section of stainless steel posts with glass balustrade. Before I formed up the section of hob that this was to be fixed to I had to prepare the reinforcing bars so they would allow the steel posts to be set into the full depth of the hob. Steel twitching tool and ties shown adjacent.
My plan included a s...

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.
