Local Basketball Legend Here to Stay? 

Washington Wizards shooting guard Roger Mason bought this five-bedroom, five-bath contemporary in Upper Marlboro for $882,000. The house is part of Oak Creek Club, a new gated golf community.

A Washington native, Mason was a basketball star at Our Lady of Good Counsel High School in Wheaton and played for the University of Virginia. After stints with the Chicago Bulls, the Toronto Raptors, and a European team, Mason was signed by the Wizards in 2006.

Landis Construction won the COTY "Best Exterior over $100,000" award for transforming this 1960s split-level in Kensington into a Craftsman-style bungalow.

A large gable hides the existing roof line and creates a warm, inviting front porch reminiscent of a 1930s-style bungalow. 

Most of you liked the remodeling project I posted last week, which was more drastic—and expensive—than this renovation. Whereas last week's project was a whole-house remodel, this one focuses mainly on the facade. Thoughts? I'm a bigger fan of this one, but maybe that's just me... 

Here's my Craisglist Scavenger pick of the week: a lipped tea table by Baker that looks to be in excellent shape. A great deal for $160, the table's large front drawer is made to look like two smaller ones. 

More Cool Stuff:

•  Contemporary Grey Sofa (with a funny story that goes along with it) for $600 
•  Grandmother Clock for $350
•  Coffee table by Baker for $170
•  Country Wood Dining Table with two chairs and two benches for $300
•  Parlor Table for $120
•  Patio Furniture for $150
•  This End Up wooden desk for $150
•  Unused Pottery Barn Rug for $400
•  Two black wood bedside tables for $150
•  Four stackable chairs from Design Within Reach for $80 each

Thanks, Craigslist!
