Other Things to Consider Before Building


It is highly important to consider the path of the sun throughout the day in summer and winter. Doing this will optimize natural light, improve energy efficiency and create a comfortable living environment.

Termite or Other Bug and Insect Protection

To protect against this you can do things like soil treatments, use certain materials that are resistant to termites or do regular inspections of the building to ensure there are no infestations.

Electrical and Water Systems

Take into consideration the utilities that are available on your site and decide what's best for you depending on what's available. An electrical plan should be designed by a qualified electrician and a plumbing plan should be designed by a qualified plumber.

Drainage and Grading

Proper drainage is essential to prevent water damage and flooding. Ensure that the site is graded away from the dwelling's foundation, and install gutters and downspouts to direct water away from the structure.

Soil Conditions

Different soils have varying properties, which affect the ability to support the building. The building foundations should be designed by an engineer and be based on the site specific soil conditions, taking into account depth of fill soils, bearing strength and reactivity of the founding soils. This information is found by having a soil test completed on the site by a geotechnical engineer.

Plumbing Articulation

Any building services that transition from the building into the natural ground should be appropriately articulated by an engineer to suit the site soil reactivity. This is to ensure that over time if there is slight movement in the soil it won't damage or break the connections that are going into the ground.

Site Plan

This will most likely be required for building approval. The documentation standards will vary depending on your location, some places will require this to be done by a licensed professional and others will just accept it as long as its up to a certain standard. Talk to your local building authority to find out more.

Anything Else

It is essential to talk to a local professional to get advice tailored specifically to your site. As each site can vary significantly there may be other things to take into consideration.
