TREE HOUSE, HERTFORDSHIRE
This 1930s detached house was extended in two blocks to create 'a diverse environment for a family'.
The first conversion saw a garage turned into a playroom at ground floor, with a study and bathroom above.
The second, an addition externally clad in English oak, incorporated the kitchen and another bedroom. The internal layout has been simplified to join the life of the family together, with the introduction of large glazed openings providing a visual connection at ground level. 'The new living spaces are linked externally by an oak deck, ' says the architect, 'which helps to draw the house into an intimate relationship with an existing walnut tree.'
