Since you said that you wanted a project that you can do on your own we did this. The garden is made from furniture elements that you can buy yourself and put them single handed on there place. There is place for you to relax on the hammock or make BBQ. You can have 8-10 person gatherings in the garden. The outside planks are easy to be place by one man. You can see that we left your tree on the same place.
The buildability is maximum for this project.
The money you have you sshould use on solar panels that will make you money in return. Also by a trampolin for the kid since you are close to watch over him. There are many planters but they can all be carried by you so you dont have to pay workers. You can enjoy working in the garden.
The house facade is simply mounted with "brick slips" - very thin nice looking bricks. They are cheap and will make the altering of the house to a minimum. For this you might need a worker to put them on.
You can make it all on your own.
