Custom Home Builder Recommendations $500-600K range

[Freedom]

Looking to build a home. ~2750SF one level, 3 car garage. Would like it to be energy efficient with quality construction/materials. Nothing exotic/special. Would like to spend $500-600K including lot. Just starting looking.

Did a search here but didn't find anything recent and the only builder name I saw was Blue Heron, which appears to do >$1M properties.

Any reputable builder names welcome. PM me if posting names is not acceptable.

Thanks in advance.

I'm currently building with https://kinghomesnsw.com.au/ and would easly recommend them (2-3 weeks from completion)
