Design, Space Constraints, Goals
This old rowhouse, like so many that our clients come to us with, was compartmentalized into small cramped rooms and was lacking for natural light in the interior. (It was what they call a “Wardman style” here in DC – but in this case, a mini-Wardman.) (insert link about history of Wardman style) Since the house was so small (less than 400 square feet per floor on each of the existing three floors) we knew right away that an addition to the house ranked high on the wish list (see “Pop-ups” & “pop-backs” below). After a few months of exploring different design ideas, we arrived at a scheme that will add a new upper level 3rd story to the house along with some modest additions on the back of the existing house. The selected design aims to open up each floor of the house by removing many of the internal partition walls on the living levels and by creating an open stairway that will bring in daylight from a three-story glass block window that will be inset into the existing west-facing alley-side wall. Glass block is a good choice for this location due to it’s inherent durability, and its ability to buffer sound better than most window wall systems. We also liked glass block since it is still a masonry (modular) product and we felt it to be a more complementary material for creating a large glass opening in the 100+ year old wall.
Expanding the Envelope: “Pop-ups” & “pop-backs"
As mentioned, this house was small – about 980 square feet total in 3 levels. If ever there was a time where a vertical addition (aka “pop-up”) or rear addition (“pop-back”) made sense, it was here. We have successfully designed several of these additions for other clients – and yes, we know that this is a touchy topic for some out there. Our feeling on the subject is that these additions are not, in and of themselves, either good or bad. There are well-designed additions – and well, those that should have never been allowed to be built. These additions should always be set back from the existing architectural features of the house, which should be preserved. When designed correctly, and in deference to the original façade and historical features of the house, these additions are an opportunity for great creativity and possibility in revitalizing old housing stock in a city faced with rising property values and a shortage of good quality housing. We also believe that the added density created by these additions is an important component of sustainable redevelopment. By adding square footage, bedrooms, or even additional living units to existing buildings we are doing so without putting a strain on new infrastructure (roads, utilities, services) that is typically associated with new housing developments. In fact, in our opinion, zoning regulations for cities like DC with so much existing single-family housing stock, should encourage this kind of increased density – the new DC 2016 Zoning Regulations landed somewhere in the middle on this topic (more on this in a later post). With well-designed additions to existing stock, we can create within our existing neighborhoods, more living space and more opportunities for families and individuals to live together within these revitalized neighborhoods.
