Cyncoed Water Tower
The red brick tower on Cyncoed Road is a Grade 2 listed building and was constructed in 1898. It’s original use was as a pumping station for the covered reservoir adjacent, now removed. It has since been converted into an upmarket dwelling. Views of the interior can be seen in in this Architect’s description and a later Wales Online article when the building went on the market in 2013.
The mansion house was originally the home to James Howell, founder of the famous department store in the centre of Cardiff. It was originally known as Grove House and was built in the mid 1890s. The house was purchased by Cardiff Corporation in 1912 and renamed the Mansion House. The Mansion House website gives some good views of the interior.
