[MassHistPres] Sunroom addition

[Dennis De Witt]

If I might add some thoughts to Rosemary's exhaustive list, based on  
personal research and experience.

I have been in the Glass House production shop in Pomfret and was  
impressed by the quality.  Ditto re another firm called Colebrook in  
Winsted Conn., which she doesn't mention and which may not survive.

I would agree that something like this should only go on the back --  
especially of an 1812 house.

It looks like she has appropriately ignored the typical "1970s"  
greenhouses, like Four-Seasons, which often are about as durable and  
inappropriate as a 1970s solar collector.

Most of these are in style and construction "english" greenhouses.   
The original designs were intended for the english climate -- nor  
were they originally designed for human occupation -- nor necessarily  
for use in all seasons.  But that isn't the way people see them here  
-- which can cause problems.   Many of them are rather lightly built  
-- England does not see our snow loads.  Many do not have very good  
ventilation -- England has mild cloudy summers compared to ours.  And  
mild winters compared to ours.

The typical english greenhouse may be more compatible in scale and  
temperament with a later Victorian house.

Let me suggest an alternative that might be much more comfortable  
with an 1812 house.  It is possible to make an addition entirely out  
of sash windows, whose walls will have 80% of the glass area, above  
the sill line where it matters, with solid wall below, where the snow  
accumulates in our climate, and to make a roof that is 80% glass out  
of Veluxes, which are available with ganged flashing.  They can be  
supported on gluelams with appropriate trim to produce an elegant  
greenhouse like effect from the inside which is much more compatible  
with the appearance of the house and will have much better  
ventilation from its sash widows and venting skylights.

Note.  All skylights leak at least a little under unpredictable  
circumstances, I would not suggest a drywall interior.  Varnished  
wood, doesn't care.

Based on my experience, such a design, elegantly crafted by a good  
finish carpenter will be less expensive per SF (but still not cheap )  
than a comparable quality "English" greenhouse.
