A lot of times it happens where people buy a house and at first glance the patio in the back looks big enough. Then they move in, and try putting a barbecue and patio set out on it and now people have 2 legs of their chair in the grass. We do probably a couple dozen of theses patio additions per year, its a little more cost effective than ripping it out and starting fresh, we instead just pour concrete around their existing slab to enlarge it. The one in these pictures was done this week, in Port Coquitlam. The other job pictured was a little entrance way on a house undergoing a major renovation.
