one of the most enjoyable adventures during my recent journeys. the huge and massive apartment building walden 7 designed by ricardo bofill's team gives you a range of feelings while you walking around the area and building itself. massive concrete blocks creating some kind of stronghold create totally different atmosphere inside. once you've entered you feel really secure although also kinda dizzy if you'll keep looking up! plenty number of lifts, halls, stairs, doors, windows all organised within a deeper thoughts to compose 18 towers that are displaced from their base, forming a curve and coming into contact with the neighbouring towers... and this is probably why you have a feeling you've seen 3 or more different buildings while this one visit!
