We love this cute chirpy headquarters of Brazilian telecommunication company Stelmat Teleinformatica. This is not your average boring office. Designed by About:Blank Architecture, the office stands out with its modern eco-friendly approach to office design. Green roofs, photovoltaic panels, rainwater reuse and sun-shading techniques like brise-soleil, among others, maximize efficiency and reduce resource consumption. There is so much color and character to this and everything just fits in perfectly.
