Description

This detached mid-century house in the sought-after Southdown area of Harpenden presents an intriguing opportunity for those looking to invest in a property with significant renovation potential. Currently, the house comprises two reception rooms and four bedrooms, making it suitable for families seeking to create their ideal long-term home. The entrance features a welcoming glazed porch leading to a hallway with access to a cloakroom and a shower room. The spacious sitting room offers charming views of the front garden along with a traditional brick fireplace, which adds character to the space. It flows into a bright dining room that overlooks the rear garden, while the adjoining kitchen, although in need of modernisation, provides ample storage and pleasant garden views. A storage room is also conveniently located at the rear of the garage. Upstairs, you'll find a principal bedroom with dual-aspect views of both front and rear gardens alongside three additional bedrooms, one being a comfortable double. Outside, the front garden is framed by mature beech hedging and includes a paved driveway leading to the garage. Accessed via a side gate, the rear garden is primarily laid to lawn featuring a lovely terraced seating area surrounded by established hedging and mature shrubs, plus pathways that lead to a greenhouse and shed. The land behind the garden consists of allotments, ensuring enhanced privacy and tranquility. This location benefits from proximity to Harpenden’s bustling High Street with its array of shops including Sainsbury’s and Waitrose as well as numerous restaurants and cafes. Families will appreciate access to outstanding schools both locally and in nearby St Albans or Hemel Hempstead. Recreational opportunities abound with sports facilities including tennis clubs and golf courses along with outdoor activities available at Heartwood Forest.
