Description

This 1930s four-bedroom family home presents a prime opportunity for renovation. Situated on a sought-after street, Sefton Avenue boasts close proximity to Edgware’s Northern line and Mill Hill's Thameslink stations, as well as convenient shopping options. The property features an open-plan reception and kitchen diner, complete with bi-fold doors that open onto a generous south-facing garden of approximately 80ft, ideal for family gatherings and outdoor activities. The current owners appreciate the strong community spirit among neighbours and the convenience of nearby Matilda Marks primary school. However, there is significant potential for further expansion by converting the loft space, pending necessary approvals. This home offers an excellent canvas for those looking to enhance its existing charm while adding value through thoughtful renovations.
