This 1900s Boston townhouse by Louis Comfort Tiffany shimmers with Islamic-style mosaics, colourful glass and copper cladding. The glasswork and jewellery designer fused eastern style with Art Nouveau forms to create this gesamtkunstwerk Back Bay mansion. It is the only surviving example of Tiffany’s residential vision, built for businessman and art collector Frederick Ayer between 1898 and 1902. #design #inspiration #interiors #architecture
