One address, read by the people who draw the pieces and the person who books the deliveries. A reply within one working day is the norm; on a delivery question, usually the same morning.
Quote your order reference if you have one — it looks like STH-2026-123456 — and the name of the piece if the question is about one in particular. Email is the only channel; there is no phone line and no shop to visit.
Same address. We supply architects and small hotels at the same prices with a longer lead time; press enquiries are welcome and photographs are available.
