Manx National Heritage has submitted plans to replace the Grove Museum of Victorian Life’s leaking roof.
It has applied (14/00864/B) to replace the existing felt roof with lead.
The work would also involve installing replacement gutters and rain water down pipes at the museum, in Andreas Road, Ramsey.
In June the Manx Independent reported that the Grove would be closing its doors early to visitors this season to enable the works to take place.
The attraction usually closes for the season at the end of October or beginning of November -but this year will close after a wedding in the grounds in early September.
Head of public services Gaynor Haxby has said that the roof had been leaking for some time.
The problem was exacerbated by the very wet winter.
Inside, damp can be seen in the walls on the stairwell, and some exhibits have had to be moved for their protection.
It is hoped the work will be completed by this winter, and that the museum will be open to the public for the 2015 season at the usual time.
The museum is the former family home of Liverpool shipping merchant Duncan Gibb, who developed the house as a summer retreat in the mid 19th century.
The Victorian villa later became the family’s permanent residence.
