The map given illustrates how the transforms were made to a small museum with a timespan of 20 years, commencing from 1990. Overall, most of the surroundings experienced a little to no modification. To be more specific, the cottage and the garden were replaced by two other amenities.
In detail, the gallery situated in the west of the map possessed an L shape in the year 1990. However, a part of the exhibition room was demolished to make way for the extension of the shop on the left-hand side from the entrance 20 years later. On the north of the map near the garden was another two galleries, which later merged into one in 2010. Despite the changes of various interiors, the restaurant remained the same.
Looking at the exterior of the museum, the garden located on the top of the map still exists after 20 years. A new cafe was constructed after the demolition of the cottage between 1990 and 2010, lying on the left-hand side of the museum. In 2010, the car park, situated right behind the entrance witnessed an expansion due to the cut down of the garden located in the southeast of the map.
