Ephraim Macht and sons built around 8,000 homes in the Baltimore area. Macht Real Estate and Banking became Welsh Construction in 1911. Many Victorian homes are a mix of styles. The beautiful home on 701 is heavily influenced by the Romanesque Revival style, popular in the 1880s. Hallmarks of the style include lots of detail, a mix of building materials, rounded windows, or door arches that show an elegant, masculine style. (The Queen Anne style features a feminine look).
That is a beautiful building, especially the ornate pediment over the door.
