The addition was conceived as a pavilion entered by a stair passing through a former window.  It opens a conversation between the original 19th-century house and the mid-20th-century garage addition upon which it sits.  The new pavilion sits squarely on the flat roof deck of the garage, its hip roof responding – without mimicry – to the mansard roof of the house.   The interior reveals a surprising lightness and airiness:  an informal space for work or contemplation in the manner of a contemporary solarium or a 19th-century conservatory.
