Mrs Smith's Cottage is a mid-19th century Grade II listed building made from early Victorian red bricks.
The range, the heart of the house, was in daily use for cooking and heating until the mid-1990s.
The only access to the bedrooms is by a ladder.
Electricity was installed in the 1930s, and the only other visible modern innovations are the coldwater tap – installed to prevent the local council condemning the cottage in the late 1970s – and an inside toilet.
The original outside privy and washhouse can still be viewed.

The cottage is named after its last resident, Mrs Hilda Smith, who lived there until 1995, when she was 102 years old.
When Mrs Smith died, villagers mounted a campaign to ensure the cottage was kept as "something special" for Navenby.

Today the cottage is run as a museum, having been granted official museum status in March 2000.
It is open for much of the year and staffed by volunteers.
The old pig sty and storage shed, deemed beyond repair, were demolished and the bricks used to construct a purpose-built visitor centre, used for exhibitions about Navenby and the local area.
