Sitting in a library at the University at Buffalo are pages upon pages of letters about Frank Lloyd Wright’s Martin House, a historic home in the Queen City that is celebrating its 120th anniversary of completion this year.

If you've ever dreamed of living in a home designed by Frank Lloyd Wright, you're far from alone. Each building's mid-century modern finishes, open living floor plans, and expansive, integrated windows that bridge the home's interior with the outdoors (while also bringing in plenty of natural light) have made the homes an iconic part of the history of home architecture - and the rarity of them hitting the market makes them extremely valuable.
