No (o) fence

This weekend we went to have a look at both the jungle and the house, the jungle to check the plot boundaries first hand, and the house to clarify our reform plans.
Reform related things which we kind of had talked about before included a lot of things for which we got an estimate from the handyman. To do them all would cost about 3,5 million yen, but actually not all of them are necessary.
Included are house cleaning, turning the tatami mats over, fixing a hole in the bathroom door's glass, fixing a small bump in the floor in the bathroom, fixing two 10 cm holes in the walls of two of the bedrooms, changing all of the air-conditioners' hoses and external covers, cleaning the filters of the air-conditioners, installing smoke detectors in all rooms, cleaning the balcony and re-covering its floor with concrete, building a huge long fence around the property to stop the cats form running out, repainting the exterior of the house with thermal protection, and the roof as well, resealing the external walls of the house, and finally since there is a 1,5 meters height difference between the garden plot and the house, building a huge and stable concrete wall between the house and the garden to protect the house from soil spilling over.
We don't really use air-conditioners that heavily, and we just kind of let the previous owner leave his air-conditioners there just in case. I can replace the hoses myself, so I removed all the air-conditioner related items. Also, tatami turning, house cleaning, fixing holes in bedroom walls sound like stuff we can do ourselves so those had to go too.
As for the fence, we had a long talk with the construction guy and went over several different alternatives to solve the issue...
They had already thought how to solve the slope, and also the long and tall fence prone to being tipped over by winds. But there were still gaps here and there that a cat could crawl through. One of them is the carport, as it has no gate, so I have to install a gate. Then there is the short fence between us and the neighbor, which needs to be made taller... Then there is a section of almost 1 meter where I cannot put a fence on as I don't own the separating wall there, so all I can do is to put something there to cover the big hole.
All these is pretty expensive and the end result will not look pretty. Plus I have to ask lots of permission from all neighbors around, all only for the cats. So in the end we decided to just fuck it and not to have a fence.
Instead, now I am toying with the idea to create green fences, such as soft nets between poles and some climbing plant to cover it and make a wall, maybe planting a row of dense bush near the short fence that makes the cat think twice before crossing it. Anyway, I have to think about the possibilities after we move in.
We also said no to balcony cleaning and covering its floor with a new layer of concrete.
The remaining stuff is pretty important and we divided it into 2 packages:
The big package which was estimated to cost about 1,5 million yen is basically cleaning, repainting and resealing the exterior of the house and the roof. I am not sure we are getting the best estimate so I want to check with other companies and pick the best one. The painter said since the biggest damage to the exterior happens in the summer, it would be wise to wait till fall to do the repainting. Plus repainting should be done in a season that is not very rainy so I gathered we still have a couple of months to find the best price.
The small package is the stuff I wanted done right away and that I thought was quite reasonably priced. It includes fixing the bathroom bump and hole in the glass door, installing smoke detectors, and erecting the concrete wall between the house and the garden. It will cost 250000 yen altogether. For that we signed a contract and they should finish within two weeks, give or take.
