Re “Heart of Glass” (9/5): The Wheaton nest of Goodman contemporaries, of which I had one, were built around 1950. They had more glass than the Hollin Hills houses: The living/dining space occupied one whole end of the house and had glass from foundation to roof. Bedrooms had a little less glass, but because there were cathedral ceilings, they each had a glass wall reaching from about 36 inches above the floor to the roof, and almost from side to side. There was so much glass that we could re-stain or paint the entire exterior with a gallon for $10 plus trim.

Goodman had trouble selling them; most of my neighbors bought them only because they were cheap—$13,000 new. I bought mine when it was 15 years old, and the valuation then set the price at $17,000. Mine was set into the land correctly for solar heat; the big glass wall faced south, and the winter sun heated the house from 10 a.m. to 4 p.m. However, this was uninsulated glass, so we pretty much heated the yard from 4 p.m. to 10 a.m. Lack of insulation was a severe problem: The walls had none at all, and the slab was only 2 inches thick (in violation of the 7-inch requirement in the building code), so in spite of thick carpeting we had cold feet.

Some of these problems were less pressing in the Hollin Hills houses, which tended to have considerably less glass than the Wheaton houses. They also had somewhat larger kitchens, with eat-in space. Back then I had friends who had one of them.
