I can't add anything to the suggestions for the house, but I can for your little baked patio.
Garden Centre. Giant pots, big pots, medium pots, peat free compost, some aquatic compost, some stones and top soil mix, lots of thick sticks (old fashioned beanpoles), twine, wire, hook eyes. I'm assuming you already have a hammer drill and thick pliers, plus some gloves and a step.
First things to get in are a grapevine (create a wire path attached to hook eyes to guide it up and across) and rosemary (the heat will help the scent emerge), along with one giant pot with no drainage holes that you'll drop a filter/pump into, together with some aquatic plants - because you have bare concrete, you can actually risk growing several types of mint without it taking over the entire street.
Fill in the gaps with pots full of other plants that love heat - thyme, oregano, chillis, tomatoes.
Soon enough, you'll have a canopy of vine leaves (maybe even some grapes), the sound of water - and with the stones, a way for any visiting birds or other wildlife to get back out again - the smell of rosemary/thyme/oregano and the sound of bees wandering in and out of their flowers, some things to add to salads so your non-cooking cooking tastes better, iced mint tea and something resembling nature instead of a purely human construct that denies the existence of anything living.
