The Sasman House was built in 1890 by Clement Sasman designed and constructed by the famous Philadelphia Architect, Horace Trumbauer (1868-1938). In addition to this Oreland Residence, Horace Trumbauer is known for other local landmarks like Edward Stotesbury's "Whitemarsh Hall" in Wyndmoor, "Lynnewood Hall" in Elkins Park, "Gray Towers" in Glenside (Now Arcadia University). In the 1920's he expanded and help to modernize the locally beloved, Erdenheim Farm. 1640 Walnut Ave has been updated over the years. The seller's father changed the original design of Trumbauer's layout by widening the rooms on the first floor by eliminating the hallway that once connected the front door to the Kitchen in the rear. While some things have changed since its construction, some things remain the same, like the original and beautifully maintained slate roof.
