Cameron Mackintosh is planning to build a five-bedroom penthouse apartment at the top of the Novello Theatre in the West End.
The theatre producer, who owns the Mamma Mia! venue, wants to turn the top two floors of the Novello into a London home for him and his partner.
According to plans seen by The Stage, Mackintosh wants to use it as a base as a “small flat” where he can also host guests, entertain people and hold meetings. The fourth floor would be Mackintosh’s home and will feature two bedrooms, with two bathrooms, a separate toilet, a study, dressing rooms, a small kitchen and sitting rooms.
The third floor would include three guest bedrooms, with ensuite bathrooms, two separate WCs, a large sitting room “with bar and kitchen facilities”, a utility room and a plant room.
The third and fourth floors of the theatre are currently used for offices, but were formerly known as the Waldorf Chambers and were once home to composer Ivor Novello.
The plans also include a roof garden, described as an “exquisite space to entertain as well as a private outdoor retreat above the heart of the West End”.
“It has also been referenced in a letter by Novello that the roof space was once an amenity area for the residence and it is proposed to restore that function,” the plans state.
The plans, submitted to Westminster City Council, show that many of the designs will be based on Novello’s apartment.
These include creating a raised platform in what was once Novello’s music room, which will give Mackintosh “views through the tree tops towards the Strand”.
“It is intended to make some of the new joinery items, like the raised tea area, from a mix of Scottish and Australian hardwoods,” the plans state.
The plans reveal that the “use of beautiful, bespoke joinery within the home continues the theme of Novello’s panelled rooms, as well as recalling Cameron’s father, the timber merchant,” the plans reveal.
The third floor would also incorporate one of the old theatre bars “and this is to be retained in its original volume as a dining room and sitting room”.
The plans also highlight how Mackintosh proposes to limit the noise coming from Mamma Mia! into the flat, including “acoustically sealed glazing”.
Mackintosh has owned the theatre since 1991.
