IN a house entirely new, character is at the option of the artist or proprietor: it may be Gothic or Grecian, whichever best accords with the face of the country: but where great part of the original structure is to remain, the additions should, doubtless, partake of the existing character. This we have attempted at Harlestone Park, the seat of Robert Andrew; Esq., near Northampton: and as few places have undergone so much alteration, both in the house and grounds, it may serve as a specimen of the combined arts of landscape gardening and architecture, in adapting the improvement to the original character of the place.
