A charming adobe house with a drab concrete courtyard was revitalized with a pool house and fountain as a focal point.   The new pool is set into turf with integral spa and baha shelf.   A comfortable outdoor room at the end of the pool has fireplace, pizza oven and barbecue.   A new koi pond and custom tile carpets add color and variety to the courtyard, along with Mediterranean plantings.    Pool House kitchen and baths also feature vibrant custom tile.
