Washington D.C. real estate development news














In pursuit of sweeping river vistas and the great outdoors, a young Bethesda, Md. family went west, in a manner of speaking, about 4.5 miles, securing a pristine lot on a Cabin John bluff overlooking the C&O Canal and roiling Potomac.
Tasked with building what would become a 4,589 s.f. four bedroom, four-and-a-half bath residence that provided comprehensive views of the evolving terrain, ecosystems and
elements in all seasons, Mark McInturff and project architect David Mogensen of McInturff Architects confronted a not-so-uncommon Mid-Atlantic region issue. With 15-foot ceilings and an expansive southwest-facing wall of glass firmly on the family’s agenda, searing sun and heat—and their impact on heating and cooling—would require more than a conventional approach to climate control. What’s more, the homeowners wanted to spend the brunt of their day in an elevated wing, embracing their surroundings
with an unobstructed view.
“When we first stood out there, the homeowner said she thought the main living spaces—living room, kitchen, dining room— should be on the second floor with the bedrooms below,” said McInturff, which he added is a strategy the firm often undertakes when considering the landscape.

In an effort to “circle the wagons,” according to McInturff, sheathing the home in adequate shading—kind of a preemptive strike before the sun heats the glass— European technology was employed in the form of computer-controlled exterior aluminum blinds. 
“They’re almost like exterior venetian blinds but much more robust,” McInturff explained. “It’s technically fairly complicated and not inexpensive, though slowly creeping into the (U.S.) commercial market.”
Also acting as a buffer at night for high winds endemic to the coastal site, the louvers essentially allow the home to be closed down. “In a way the house is active,” McInturff said, affirming at the same time he does not endorse filled or tinted glass. “That’s like sunglasses or a Band-Aid. There’s a better way to do it, which is to prevent the sun from reaching the glass in the first
place.”
With optimal energy efficiency on the homeowners’ dance card, geothermal HVAC systems, soy-based foam wall and roof insulation at R-21 and R-38 values, respectively, radiant heat throughout and passive strategies such as cross ventilation were utilized. On the entry side, which faces away from the river, a pitched roof provides for an 8-foot ceiling which ascends to 15 feet, accommodating the glass wall and band of clerestory windows. “Fifteen feet is a comfortable height which does a lot in terms of gathering natural light into the space; it becomes quite luminous,” McInturff said. An exterior overhang also precludes sun from flooding the space at this height, as the clerestories don’t have blinds.
On the lower level, two children’s bedrooms with 9-foot ceiling height, a bath and a “homework room” share a courtyard, with a master suite and private courtyard completing the composition. An outside paving motif is teased inside this level with the inclusion of a porcelain-tiled entry. A guest suite is featured above a garage, connected by the upper level living spaces, but which reads like two buildings.
On the exterior, factory-finished metal siding and metal-clad windows provide for a tighter, more energy-efficient envelope, with masonry used for the same purposes on the home’s lower level. When the sun goes down, indirect and strategic uplighting are key components in the residence’s energy conservation quest.
According to the architect, a balcony or loggia with durable ipe decking was located off the second level on the view side. Here, too, operable aluminum blinds off the railing can protect the home and outdoor materials from the ravages of intense sun, with the added aesthetic of a modified closure providing a beautiful, dappled light.
“It’s a house we really love and have put a lot of work into,” McInturff said.


Walmart, in response, launched a Web site to help convince skeptical residents and activists that its presence would be a boon to improving access to groceries in poorer neighborhoods as well as provide jobs to DC residents, at least 1,200 spread out amid the six stores, and also 400 construction jobs. Walmart says that Washingtonians spent $40 million at its stores outside the District in 2010. Walmart also noted that the stores would contribute $10 million a year in tax revenue to the District. "The District is anxious to see something happen," Maier said. "It's not all 100 percent approved but its pretty close," he said.
Walmart now has expanded its plans in the District to six stores, all of which it says will be open before the end of 2012. Besides New Jersey Ave, there will be two in Ward 4 with one at Georgia Ave and Missouri Ave. (rendering at right), where some site prep work is happening as well. 
Groundbreaking for Lot 31, the public-private StonebridgeCarras-PN Hoffman project on Bethesda Row, in the works since 2004, missed its January target date after being delayed yet again. But lead developer Stonebridge and Montgomery County government officials say it's not because the project is flagging on the home stretch - nor was the delay a response to complaints from local businesses about the closure of the lots and of Woodmont Avenue during construction.

Already the District has two lines under construction, one in Anacostia and the other on H Street NE, where more than two miles of tracks have been laid as part of a Great Streets revitalization. The District recently agreed to expand service over the H Street "Hopscotch" Bridge to connect the streetcar system with Union Station and to buy two more cars in addition to the three in storage in Greenbelt. Both lines are expected to begin limited service starting in mid-2013 with some on-rail non-revenue testing of the Skoda-Inekon-built cars beginning this year, Tregoning said.
