One of the most difficult jobs in the building business is “whole house” remodeling. At O’Neill Development (OD) we call it “graduate work” because of the degree of difficulty and the knowledge required to manage such a complex job. OD is currently involved in a whole house remodel in the Palisades area of Northwest Washington, DC. The work actually started with demolition of the entire rear of the house including one corner and half of the existing roof. The difficulty was in holding up multiple floors and the front gable of the 3 story roof while the extension was added. This involved inserting large intersecting steel beams to support the upper floors in place of the rear walls and the corner of the house that was removed. It should be noted that removing the corner of an existing house creates huge risk in potential “racking” of the entire structure because it removes 1/4 of the support of the house. Our crews successfully completed this difficult maneuver with speed and efficiency.
Of course when a new extension is added, it must be accomplished in such a way to create a seamless addition to the original house.
In the images below one can see the original gable shape of the house and the sequence of pictures showing the side of the house with the rear corner and roof removed and the beams in place to hold the upper floors to accommodate the extended first floor.
O’Neill Development has accomplished many of these complex jobs over the years. This particular renovation was designed by the North Carolina architectural firm of Meyer Greeson Paullin Benson for a couple from North Carolina, both of whom hold down demanding jobs. So the additional difficulty of sometimes long distance communication and coordination to make sure all details and owner/architect wishes were executed precisely was an additional challenge. But OD field and site staff have brought this complex project to the finishing stage and are scheduling completion late this Spring. Hats off to Rob, Kerri of OD and their respective teams.
