Glass brick and more glass brick — in the form of 4-square dots and tall shafts — let in the light in this warehouse district townhome built by Edgefield Developers in 2005 as part of a 3-pack. But it’s the ample deployment of recessed lighting that really amps up the interior. The towering property sits on the corner of a fenced, half-built half-block just west of McKee St. and north of a Metro bus barn near a bend in Buffalo Bayou and its bike trail. The home landed on the market earlier this month, asking $645,000.
