Welcome to the most interesting building in Brooklyn -- the original office of the William Ulmer Brewery.Designed by famed architect Theobald M. Engelhardt in 1885 and described by Brownstoner as a "Romanesque Revival Masterpiece in the German Rundbogenstil (round arch) style of architecture," this fully detached two-family mansion features everything you could imagine in a historical masterpiece: Soaring 13' ceilings with arched windows on three sides and giant skylights above; cherry wood floors and moldings with various types (Carrara, Rosa Aurora, Grays Creek, etc.) of marble and granite fixtures; a beautiful wrought iron fence opening into a cobblestone courtyard en route to your 530' private garage; and a Mansard roof highlighted with terra cota trim and tons of original detail...they simply don't build to this level of quality anymore.This listing is for the newly vacant downstairs unit (not the entire building), which boasts nearly 3,300 SF without including the full basement, and is full of original details and history. It is truly unique and can be purchased on it's own in a partnership with the upstairs tenant. For investors, the M1-1 zoning allows any commercial use in one of the Brooklyn's most quickly-appreciating neighborhoods, with an average retail rent of ~$50/SF. This offers investors a unique opportunity for substantial short-term cash-flow, and capability to sell at a premium down the road. A pro-forma can be provided upon request, and the building has been approved for either residential or commercial financing.Please feel free to reach out with any questions, and take care of yourself during this unique time!
