Between Primrose Hill and Belsize Park, tree-lined streets of Victorian villas form a picturesque triangle around St Saviour’s Church. Among them, concealed by a sylvan oasis of calm, can be found a rare lateral expanse of architectural distinction. Birchwood House is the work of RIBA-award winning practice, Eldridge London, and combines an existing red-brick Arts and Crafts house dating to 1860, with a sprawling glazed observatory to the bursting flowerbeds and gleaming silver birch that envelop it.
The interior, which spans almost 4,200 sq ft over two levels, has been designed with versatility of arrangement in mind. In its current form it offers four bedrooms along a first-floor gallery in the old house, and a fifth in the south-western corner of the contemporary section. Plans have also been conceived in which certain rooms are easily combined to provide three larger suites in the original section of the house, and to include the option of a gym at ground level, while maintaining a fourth bedroom suite in the new portion.
