    Stricter Pursue picks

    We've tightened what earns a Pursue. A home now needs a published valuation, a strategy that still makes money after real running costs and lender stress tests, and no listing problems that would stop a mortgage. You'll see fewer Pursues, and each one has been checked harder.

    About

    The property

    A beautifully presented and thoughtfully improved three double bedroom semi-detached family home, situated within the popular St Edeyrns development in Old St Mellons.

    Generously proportioned throughout, the property offers spacious and versatile accommodation arranged over three floors, together with a double driveway and a larger-than-average south-westerly facing rear garden.

    The property is presented in excellent condition and provides a lovely welcoming home arranged over three floors.

    To the ground floor is a comfortable living room, providing a pleasant space to relax, together with a modern fitted kitchen and useful downstairs cloakroom.

    The first floor offers two excellent double bedrooms, both providing good-sized and versatile accommodation, together with the recently upgraded family bathroom.

    The second floor is dedicated to the impressive principal bedroom, creating a lovely private retreat away from the main family accommodation.

    Outside, the property benefits from a double driveway to the side, providing valuable off-road parking.

    To the rear is a particularly attractive enclosed garden which is larger than average for the development and enjoys a desirable south-westerly aspect.

    There is plenty of space for outdoor seating, entertaining and family enjoyment, with the garden providing a lovely extension to the living accommodation.

    The location is particularly convenient for everyday life.

    St Edeyrns has its own primary school and green spaces, whilst a range of supermarkets and local amenities are easily accessible, including Waitrose, Asda, Aldi and Lidl.

    The development also offers excellent access to the A48 and M4, making it particularly convenient for commuting, while regular bus services provide links towards Cardiff city centre.

    This is a lovely family home offering spacious accommodation, excellent presentation and a highly practical layout over three floors.

    With three double bedrooms, modern kitchen, downstairs cloakroom, double driveway and an unusually generous south-westerly facing garden, this is a property that deserves to be viewed.
