K. Mactaggart and J. Crane have applied to the Queenstown Lakes District Council to undertake additions and alterations to the Threepwood Homestead, overlooking Lake Hayes, which dates back to 1909.
The homestead is a category 2 heritage building under the council's district plan.
The application, prepared by John Edmonds and Associates, said the large timber frame house was run down and needed to be upgraded to provide for ''suitable living and more durable construction for its future longevity'' and enable it to be used as a family home.
The property was owned by Threepwood Nominees Ltd. The company director had provided written approval for the work, as had the New Zealand Historic Places Trust.
Changes proposed to the homestead included the removal of plaster to expose the original weatherboard and reinstatement or exposure of the original architectural features, including the original veranda and windows.
Reinstating the service wing, which had been removed, was also proposed, along with the ''rearrangement'' of internal spaces and the addition of a new, modern veranda to the north.
It was also proposed to repaint the property to represent its original colours - an off-white exterior and a dark grey roof.
Consent was also sought for a traditional two-bedroom guest cottage at the rear of the existing footprint of a three-car garage, which would be removed.
Two garages were proposed - one behind the house and one where the existing cottage was. The cottage would also be removed.
The application said the applicants sought to establish a swimming pool in front of the guest cottage, retain existing landscaping and proposed more.
Positive effects of the proposal were the restoration of the heritage building and that the use proposed was consistent with its historic use rather than an adaptive re-use.
The council's resource consent application list showed further information was requested from the applicants.
