Glenn Howells Architects has been appointed to outline what effect a high-speed rail route through Birmingham would have on development plans for the city.
Birmingham City Council hired the firm after it was announced in March that the rail route would be built with a station in Eastside.
The council had already earmarked the area for regeneration, with plans for a new university campus, park and housing developments.
These plans may be affected by the railway, which will connect London to Liverpool and York. There is a chance the rail route will not go ahead now that a new Government is in power, but a spokesman for the council said this was unlikely.
He said: “The route might not be built for 20 years, so we want to know what parts of our plans we can progress without having to wait that long.”
The managing director of the firm, Glenn Howells, said: “The announcement that the planned station linking Birmingham to London in 45 minutes will be in the heart of Eastside presents huge opportunities and significant challenges if the full potential of the new station and this part of the city are to be realised.”
