The typical verandah or patio is a rectangular extension along the back or side of the house that allows you to enjoy a place of relaxation without going outside.
Since it is completely roofed over and attached to the house, it becomes part of the house but still allows you to step out into fresh air without being ‘outside’ as it were.
Some people break with the traditional idea of the verandah and create an outdoor space that is truly luxurious, being much larger than the usual long, narrow area.
