Today I took the plunge and ordered an ISE Drying Cabinet which is the best - if expensive - clothes dying solution that I could find. Clothes drying is a major source of moisture, which in an eco-house won't be able to escape, so hanging up clothes within habitable rooms won't be allowed - hence the need for the drying cabinet. This is something like a modern-day version of an airing cupboard, with moisture from the clothes taken out via a duct to outside air.
Like all the other large and/or novel elements of the design, I'm taking the approach of buying things in sooner rather than later, as physically having the items helps understand what's required to make them work as intended, and avoid "gotchas". With the drying cabinet, the manual isn't clear on how long a load of clothes will take to dry, so we're going to set it up at my house initially, to see how it performs; there's also a height issue, as the basement ceiling is only 2m high, and we need to be careful with door lintel heights etc, that we can actually get the unit in!
In other news, the Velux windows are now ordered, roof work is ongoing. Also got an email from the neighbour, so we're now in dialogue via email.
This weekend I'm going to visit Redfield Community - a housing co-operative that's been going 35 years.
