Nottingham architect Letts Wheeler has beaten a strong field to win a RIBA competition to redesign the Market Square in Northampton. Its design saw off efforts from rivals Panter Hudspith, Ash Sakula, Snell Associates and John McAslan + Partners. Letts Wheeler also won out over an entry from Northampton's favourite architect son, Will Alsop, who has also worked up designs for a "cultural mile" throughout the town. Northampton council will now develop Letts Wheeler's plans.
