Welcome to our 50th issue. To celebrate, we’ve asked 10 of the world’s most in-demand architects and designers to name their five era-defining products. As with every September issue, we explore exceptional living within the fabric of existing buildings – this time in Belgium, France, the US and Australia. Highlights from Maison & Objet and Paris Design Week also reveal our constant search for inspiration and ideas – the undercurrent to every digital issue of est magazine.
