Kerri Erler, Owner Teesdale High Performance House

Working with Aphi Projects to achieve my vision for my ideal home was easy. My aspiration of a home that met key sustainability principles and delivered on my design outcomes within my budget was always their aim.

The team were willing to go that little bit extra to make it happen and were always clear on budget implications of the bespoke elements I was after. To top it off they are just lovely people to work with – we clicked! as they say. I had full trust in them to deliver and they did.
