A beautiful house can only be so when the windows of the house are right. All too often today houses that would otherwise be beautiful are not because of choices made in the placement and selection of windows. While there are many issues of good design that affect the cost of a building, placing and selecting well-designed windows do not. In the past, while directing the ICAA’s Program in Classical Architecture for Design and Construction Professionals, I have seen a wide range of today’s houses and common window products and have thus been able to see many of the most typical errors in fenestration. For a catalog of windows and their details visit my collection of windows.
