Elevating your property's potential...

Let's walk you through this 2-bedroom Granny Flat we did last year in Padbury as an investment property.

Nothing has been missed. Kitchen, Meals and Living areas. Separate Laundry facilities and generous Bathroom to facilitate the 2 good-size Bedrooms with larger than average robes. The space even allowed us to fit in a gorgeous Alfresco area.

A Granny Flat like this might just be the ticket for your place.

Reach out if you'd like to discuss and see if we can elevate your property's potential.

Our recently completed 2 Bedroom, 2-bathroom Granny Flat in Ellenbrook.

Blending seamlessly with the existing home, cause that's how we like it.

Our Granny Flats elevate your property's potential, not detract from it.

This is the best way to get maximum return on your investment.

It's the style and quality of workmanship that sets us apart from the rest.

13/01/2025

We're in the final stages of construction, for this 2-Bedroom Granny Flat in Ridgewood ensuring that everything is perfect for its new owners.

This custom design made the most of the irregular shaped block and the space we had to work with, something you can't get from a pre-fabbed Granny Flat.

We are proud to offer designs, built to suit your personal needs and site requirements, and why pre-fabbed construction is NOT for us.
