The people living in a house that looks like a castle on one of Cardiff's busiest roads

Many thousands of people over the decades have driven up, or down, one of Cardiff's most well-known routes and surely a substantial number have noticed a house that stands out from the crowd - because it thinks it's a castle.

Unique is a fitting word for the five-bedroom, detached house because where other homes have a normal, and possibly described as boring, front façade, this abode can boast a two-storey castle tower complete with castellations on the top.

Rumney Hill is part of the Newport Road route into Cardiff city centre, The Castle House is well-positioned for shopping at the national brands of the sprawling retail park at the bottom of the hill that was once Rumney Common, from kitchens and DIY to home brands, electricals, sofas, pets and supermarkets, as well as public transport into the capital.

The castle tower at the front of the property's design is the feature to focus on, making this home hit a higher level of interest than its neighbours.

Of course, as soon as you step inside you want to know what is in the castle tower - a castle dungeon, a princess bedroom, an annexe for Rapunzel?

To discover the castle tower it is a very clever way to find a home for the staircase within the property's floorplan might disappoint some people, but how many homes in Cardiff, or even Wales, can boast such a unique staircase - apart from actual castles, of course.

As you climb the partly spiralled staircase there are even two slit windows that mimics the arrowslits found within the robust stone walls as a vital aspect of defence, for this house it's a cool way of getting in more light while reinforcing the castle tower scenario.

The three-storey, five bedroom, three bathrooms house is a much-loved home that can offer a very sociable lounge kitchen diner at the rear that opens out onto a sunny patio and garden that includes a detached garden room perfect for a multiple choice of uses - bar, hobby room, artist studio, cinema? - and a handy storage building, as well as a garage, parking for four cars and an EV charger.

Up the castle tower stairs there are four bedrooms and two bathrooms on the first floor before climbing again to discover the top floor - a sanctuary to find peace away from the busy family rooms below - a spacious bedroom in the converted attic with an ensuite shower room.

The Castle House is on the market for £650,000 with estate agents Sheppard & Bear, call 029 2105 1927 to find out more. For more property, renovation, and real life stories join our Amazing Welsh Homes Facebook group here.

It would have been a pretty period property to call home, with space for four cars and an EV charging point, but with the castle tower within its design it becomes and landmark building in Cardiff, a design feature that can elevate its prominence above its neighbours.(Image: Sheppard & Bear estate agents)

Welcoming hallway gives access to a handy office to the left that leads to a cloakroom and storage area but it's the staircase that is the feature that brings the uniqueness to this much-loved home.(Image: Sheppard & Bear estate agents)

As you climb the stairs the design of the castle tower takes over from the standard staircase you find in most other houses - including an 'arrowslit' that thankfully is not needed for defence but shows commitment to the castle design, and so is a handy little window.(Image: Sheppard & Bear estate agents)
