Images have been published of a £68 million scheme that would completely redevelop an old granite quarry in Aberdeen.
Canadian developer Carttera wants to construct a complex at Rubislaw Quarry with 300 flats, a gym and a 'heritage bistro' featuring a permanent exhibition on the site. The pit itself, which is 466 ft deep, will not be filled in.
The project would include a building of up to ten storeys in height, with its design resembling blocks of granite.
Carttera's plan is a rival to an alternative proposal by local businessman Hugh Black for a heritage site on the south and west of the site, which would actually overhang the pit.
The focus on the history of the site is significant because it was from Rubislaw Quarry that the granite from which the city takes its nickname was dug.
Carttera has set out its firm opposition to Mr Black's idea, with the firm's chief Jim Tadeson saying its plan would better protect the "natural state" of the site.
He added: "We want to pay tribute to this history through the architecture, and publicly accessible spaces within the building. We have another heritage centre proposed next to us, which we have been opposed to all along.
"We have always believed that the area where that centre is proposed should be preserved in its natural state."
Mr Tadeson said Carttera is "vehemently" fighting the local businessman's scheme, but Mr Black has run into difficulty in any case as the quarry company has been locked in dispute with the Scottish Lands Tribunal over its attempt to change the deeds of the site to enable the plan to proceed.
The construction sector in Aberdeen has been kep busy recently with the A90 bypass and new city centre developments are on the way. However, the Rubislaw Quarry question adds to the uncertainty about some proposed projects.
Aberdeen Football club's plans for a new stadium on the western edge of the city is a particular doubt, after the club recently withdrew the application to give itself more time to discuss the project with city planners, after a concerted effort by some local residents to block the scheme.
