The scheme comprises a 43-storey residential block next to a 27-floor hotel.
When built it is understood the Snow Hill residential tower will become the second tallest building in Birmingham - only a few metres short of the BT Tower.
Yesterday Eric Kuhne's striking 50-storey V building, proposed for Arena Central, Birmingham, made its international debut at MIPIM (Kuhne unveils 50-storey tower for Birmingham).
According to Glenn Howells, the gap between Snow Hill's two towers is intended as a gateway which will 'create a sense of arrival' and 'frame' nearby St Chad's Cathedral.
Project architect Stephen Spencer said: 'Generally comprising anodised aluminium, glass and polished concrete, a great many options for the size, shape and location of the building have been considered during the course of the scheme.
'The building responds to the height of existing buildings in Snow Hill. The curved and tapering form of the plans, together with the quality of the materials and the modelling of the facade, will create a building with a distinctive shape that responds to the changing effect of daylight,' he added.
Construction is expected to begin on site in July or August this year.
