GEOCON Commercial Holdings hopes to construct six buildings on prime land on the corner of Anthony Rolfe Avenue and Gribble Street.

The 17,264 square metre site would feature $25 million of office space in two buildings expected to be up to 12 storeys high.

Four remaining buildings would host a mix of business and retail ventures, including a childcare centre, a gym, cafe, restaurant and outdoor play area.

The plans include two levels of basement parking as well as undercover parking on the ground level.

The ACT government has announced it will move 500 workers from the Treasury Directorate out to Gungahlin and has shortlisted five companies - KDN Group, Capital Property Group, Amalgamated Property Group, Doma Australia Holdings and Landco - to provide that office space.

GEOCON development and design manager Michael Andrew said his company was part of a consortium with one of the five companies listed but would look at lending the office space to private businesses should the application be unsuccessful.

''We have six buildings proposed on the site, one of which has been designed specifically for a government department should they wish to take up that building. This development application has been submitted entirely independent of that process. If the application [to host the public servants] is unsuccessful, we would seek other tenants.''

GEOCON Constructors is a Kingston-based company with $120 million of development already under way across the city.

This includes the Vue apartments in Tuggeranong, the Fringe at Epicentre commercial suites in Fyshwick and Abode Hotel in Gungahlin, which sits directly opposite the proposed business park.

The company has also completed residential buildings in Kingston, Harrison, Bonner and Franklin.

In the development application, the company says its proposed business park is on a premier land parcel in the suburb.

It is a corner block with primary frontage to Gundaroo Street and is close to public transport corridors, the Gungahlin town centre, Yerrabi Ponds and several schools, shops and childcare centres.

Mr Andrew said the company had already received strong interest from several parties looking to rent the space and had received a warm response after a presentation to the Gungahlin Community Council.

''The Gungahlin community has been seeking to a have a business district with a large government department out there for some time now and we are looking to … meet their needs,'' he said.

''We've had strong interest from a number of parties … but obviously we would welcome having a large government department in that space.''

It is understood the ACT government will cut its shortlist of preferred developers down to three at the end of the month.
