When we first visited the house the Realtor actually suggested we take down the oldest section of the house and just keep the front. Granted, there are valid arguments for that (no insulation, low ceilings, jam packed with ceramic cat trinkets), but we saw potential... or at least the glimmer of something.
Today we took the first step of that idea coming together, the solarium has glass. Not a lot of glass, really just three good sized skylights, but they make so much difference. On the inside we are opening up the ceiling to the attic (which is quite large) and creating a double height space which we hope will be bright and airy. A good spot to hang out next to a wood stove and feel cozy in the dead of winter; or on summer days, a nice place to open the double doors and let the breeze in.
