So many people pass this house every day on this busy Old Town road, but not many people get to see inside.

Nor do they see the radically different extension at the back, which is seller Richard James’ favourite part.

From the front, the Victorian terraced house in Bath Road maintains a traditional look, with the owner keeping many of the house’s original features.

The door opens onto a ‘beautiful’ entrance hall, and a large dining room with an original fireplace.

But as you start to move through the house, you also move through the centuries as you enter more modern spaces.

First, there is a ‘bright and airy’ living room with underfloor heating with light entering through the glass extension.

Agent Richard James says: “One of our favourite things about this house is the rear extension. 

“It lets in an abundance of natural light to the kitchen and living room and opens up to a patio with an electric awning – perfect for enjoying sunny days or hosting a BBQ.”

Pictures show sun loungers, an outdoor seating area and a sunken dining area. 

With the hottest week of the year having just passed by, and promising even hotter temperatures to come, the garden is ‘ideal for chilling out or playing with the kids’.

The sunken area leads down into the kitchen through further steps. Meanwhile upstairs are three bathrooms and four bedrooms.

There is a double garage for your car with an office above which other properties have suggested could be turned into a kids play area.

However, this house is not just suited for the sun. There is also a pool table for rainy days or evenings after dinner.

The agent says: “[A] Victorian terrace home that's as cozy as it is elegant. This house is a real gem, being meticulously restored throughout by the current owner back into a house from offices.

“The owner has taken great care to keep all the original features intact, giving the house a unique charm that you won't find anywhere else.”

The house is selling for £850,000. According to the Land Registry, it sold for £320,000 in 2010 and only £135,000 in 1997.

That is more than a 592 per cent increase from 1997 to today - this ‘little treasure’ is becoming more like gold with every year.
