106 Jermyn Street converted a former tailor’s workshop into four high quality residential units for letting in a narrow Grade II listed building. The project involved the refurbishment of the basement and ground retail unit with a new core at the rear of the property that includes provision for a lift. M3 was involved from the outset, reviewing the development options for the 106 Jermyn Street building, including the improvement of the retail unit on ground and conversion of the upper floors to residential.
