Heartlands homes get the go-ahead from Cornwall Council
Cornwall Council has given the go-ahead for the next stage of a £35m visitor attraction.
Heartlands has been created at the Robinson's Shaft of the former South Crofty mine in Pool.
Work will begin in the autumn on 138 new homes as well as new shops and office space.
Heartlands has craft studios, botanical gardens representing countries Cornishmen mined in and the biggest adventure playground in Cornwall.
The houses, a quarter of which will be classed as "affordable", will include high levels of insulation and be securely airtight, as well as having triple glazed windows and photovoltaic panels on roofs.
Set in 19 acres on industrial wasteland and with 400 years of mining history, Heartlands forms part of Cornwall's World Heritage Site.
