Four years, of which about six months is actual building
The timeline
Two years of survey and consent, one of fundraising, and about six months of work. That order cannot be rearranged.
Why so long
It is a scheduled monument. Consent requires a written scheme of investigation and an archaeologist present throughout. Both are legally required.
What is needed now
Nothing physical. Two people willing to help with grant applications, which is the entire activity for the next eighteen months.
