(MD) (Friends of Sligo Creek) Join us on a roughly one hour walk looking at the different ways houses are built for and respond to their sites adjoining park land along Sligo Creek. The architectural design of homes along the stretch of Sligo Creek from Maple toward Piney Branch is uniquely varied and adopts the styles, ideals and the evolving design trends of 20th and early 21st century residences. During this walk we will identify different architectural features of selected homes and how (or whether) they successfully establish a relationship to their natural environment.
