"They shall grow not old,
As we that are left grow old;
Age shall not weary them,
Nor the years condemn.
At the going down of the sun
And in the morning,
We will remember them."

Elegant simplicity 💙

This living room was part of our second story addition of a family home in Glenelg North.

A special feature we are super proud of is the sourcing and use of 90-year-old floorboards to match the existing flooring, which allowed for not only the same visual aesthetics flowing from the original home into the new extension, but similar acoustics underfoot, providing total continuity in the finish of the design.

With a bunch more housing estates being released, it’s important to understand the impact of soil types before building your new home…

We explain how to understand the different Adelaide soil types and how they can affect the need for underpinning.
