Scheme is at grade I listed structure on Marylebone Road
Heritage specialist Caroe Architecture has won an £8.5 million scheme to carry out work at a grade I listed church in central London.
St Marylebone Parish Church dates from 1814 to a design by Thomas Hardwick and underwent a revamp in the 1980s and 90s with the addition of a medical centre.
The latest work involves adding a new pavilion entrance, opening onto the public gardens and enlarging the crypt to the east side. The plans also include a new cafe.
The scheme is being bankrolled by lottery money and other members of the team include engineer Alan Baxter Associates and landscape firm Robert Myers Associates.
