West Hendon Phase 4 (Blocks K1 and K2). Block K1 is the third building delivered by Makower Architects at West Hendon for Barratt London and was handed over recently. We recently returned for a site visit to see Block K2 progressing well, with the frame of the tower now being completed up to level 21. We love the eroded enclosure created here for these top floor balconies, wtih chinks of openess on the sides and the roof.
