Over ten years ago, as one of Grand Design's first projects, Andrew Tate and Deborah Mills found a site with a monstrous, dilapidated, 100 foot tall water tower on it. Unusually, they saw it as the perfect spot to build a contemporary family home and convert the old water tower into a seven-storey bedroom wing. Andrew is a commercial architect and so the modern new build went up in just four months, using fast-track methods alongside unconventional building materials. However, things were not so easy when it came to the three feet thick water tower: a doorway they expected to be made in two days, took two weeks. Kevin went back to see Andrew and Deborah three years after they had moved into their contemporary extension, but they had still made no progress on the water tower, and were living with minimal bedroom space. Now Kevin returns again to see if the water tower conversion has finally happened, and if their dream home has worked out just as they envisaged all that time ago.
