Description
If you’re here, you probably know that building homes in a more sustainable and independent way is not just increasingly popular, but also grows more and more vital every year. It’s a growth industry with viable prospects and a widespread culture of positivity.
The skills you will develop here can be applied in a multitude of ways. Maybe you’re looking at building your own house? Maybe a career change? Or maybe just because you’re passionate about the application of heritage methods in a modern context. Maybe you can’t commit to a full-time residential build course and want to dip your toe?
Whatever your motivation, you will gain an industry-leading education to build from. And build upon.
