About ALTECH Construction
We are a residential builder based in Leppington, working with homeowners across South West Sydney on new homes, granny flats and the outdoor work that goes with them.
Who we work with
Homeowners planning their next step
Some people come to us with a block and an idea of the home they want. Others want to make better use of land they already own, with a duplex or a granny flat out the back.
Each project starts with a conversation about the block, the budget you have in mind, who will live there and how you want the home to work day to day.
Being based in Leppington, South West Sydney is where we focus our work.

Inside and out
A home is more than its frontage. We talk through layouts, kitchens, bathrooms and finishes with you, as well as how the yard, driveway and levels will work once the build is done.
