Hi All,

If you are thinking to buy a section for your new home I would strongly recommend that you search for a flat section because there could be a huge foundation cost difference between a flat and steep section.

Building Foundation For A New Home On Flat Section

If you build a new home on a flat section the construction cost of foundation for your new home will be relatively cheap.

You can just build a rib raft concrete foundation (concrete slab) overthere and its cost for the standard sized new home could be less than $40,000 – $50,000 (excluding GST and depending on the soil condition)  .

Below is the single storey new home Japan Homes recently built.

We just put a rib raft concrete foundation on the flat ground.

Solid, quick and very cost effective construction.

Foundation on A Steep Section

Building a new home on a steep site would be a different story.

It depends on how steep is the ground and how you design your new home, however, the foundation cost could be more than $80,000, $90,000 or even more than $100,000.

This is due to lots of earthwork and retaining wall required to support the foundation.

Example here.

This is not our project but my neighbor’s site.

Very steep.

So builders needed to excavate a large part of the site and built concrete block retaining wall around.

And it required lots of backfill that is also costy.

Foundation complete.

You see lots of concrete block wall had to be built.

In Summery, building foundation on a flat section is much easier, quicker and cheaper than a steep section so you should look for a section like this.

Good Luck for your section search!!

I love architecture and design so much that I have been to so many buildings and places around the world such as Sydney Opera House in Sydney, CCTV building in Beijing, Empire State Building in New York, Royal Palace in Bangkok, Houryu-Ji in Nara, etc. However, the residential building attracts me the most. For nearly 10 years I have visited heaps of local and historical homes around New Zealand which I feel the builders’ great workmanship as well as occupants’ life.

From this experience my aim is to design and provide the comfortable and affordable houses with the spirit of Japanese workmanship that people enjoy and improve their quality of life.

In this blog I write my everyday experience of work to show what is a designer’s work and how it goes at Japan Homes.

Any comments or questions are very welcome.
