A controversial £35m flats plan for one of Glasgow's plushest areas has been given the go-ahead.

A row broke out in March after a property developer lodged an application for a multimillion-pound flats development at Park Quadrant in the west end of the city.

Park Quadrant, which is next to Kelvingrove Park, was sold by Glasgow City Council to English-based developer Expresso for £6.3m.

The council received more than 200 letters of objection from residents and around 80 letters of support.

The firm has now been given permission to build 98 flats on the site worth around £35m after councillors voted through the proposals on Tuesday.

Eleven members of Glasgow City Council's planning applications committee voted in favour of the proposals while five voted against after a debate lasting two and a half hours.

A spokesman for the council said: "I can confirm the planning applications committee approved this proposal."

Nick Robinson, co-director of Expresso Property said: "This is undoubtedly one of the best addresses in Glasgow. One of the key concepts throughout the evolution of the design was to create a luxury, high-end product that forged a dynamic link between old and new.

"The design follows the original approach within the area, to celebrate the very best standards of living and their relationship to their park-land setting and the wonderful urban spaces of Park District."

STV News revealed in May that architects at the centre of the plans are being probed over conflict of interest claims in relation to the letters of support.

The investigation is centred on accusations that several employees at Holmes Miller, the agents for the developer behind the proposals, sent the letters to Glasgow City Council. Two other engineering firms linked to the project are also involved in the development.

A number of MPs previously waded into the row with SNP MP for Glasgow Central, Alison Thewliss, raising the issue in parliament at Westminster to urge the city council to consider alternative development options for the site. A further nine MPs signed in support of the early day motion.

Ms Thewliss called on the council to halt the project, claiming sites such as Park Quadrant should be preserved for the benefit of the local community.

Glasgow SNP MPs Christopher Stephens and Patrick Grady and fellow nationalists Martyn Day, Martin Docherty, Angus MacNeil, John McNally and Paul Monaghan supported the motion, as well as independent MP for Glasgow East Natalie McGarry and DUP MP Jim Shannon.

Residents claim their alternative proposal for public gardens and a pavilion on the site was hampered by delaying tactics by the council.

They claim officials have refused to process their planning application because they have failed to complete an environmental assessment of the site.

The probe into the architects is centred on complaints they acted unethically by encouraging staff to lodge letters supporting the scheme to exaggerate its popularity.

The Architects' Registration Board (ARB) and the Association for Consultancy and Engineering (ACE) are looking into complaints that Holmes Miller, Woolgar Hunter and Atelier Ten triedto mislead Glasgow City Council's planning committee with the letters of support.

It is alleged more than two dozen staff, including the managing director of Woolgar Hunter and several directors of Atelier Ten, wrote to the council praising the scheme without making clear they had a financial interest in the project succeeding.
