Stunning Renovation for Lowenstein Sandler LLP Completed. Sweetwater, as construction manager, delivered the quality and innovative space this national client had envisioned for its relocated headquarters. A new sophisticated exterior facade and vestibule announces the impressive interior space of 160,000 square feet, spanning 3 floors. A team of ten – management, architects, engineers, and consultants – collaborated successfully to provide the design, function and application. Architectural wood wall panels, high density shelving system, and custom stainless steel railing and cable staircase, are a few of the highlights within. Click here for more information and photos.
