Residents of a high-rise condominium complex at 939 Coast Blvd. approved minor construction upgrades that started more than one week ago, giving the waterfront building a minor facelift. According to resident and local real estate agent Gregory Thomas, the 44-year-old, 21-story residential building needed some restoration, so C.A. Marengo, of Marengo Morton Architects, designed a new facade and lobby expansion.  “This is part of ongoing improvements,” Thomas said. “Everybody’s going to wonder what’s going on when they drive by the construction.” Thomas said the upgrades would escalate property values, adding a water feature to the front façade facing Coast Boulevard.  “It’s going to look less like a hotel and more like luxury condominiums,” Thomas said. The building originally housed 164 units, according to Thomas, but some residents joined units. Recently, the association upgraded other features such as a billiards room. And residents plan to continue improvements, focusing on areas such as landscaping, he said. For information, visit www.marengomortonarchitects.com.
