The reason for actually TRAINING the branches to grow horizontally as JONA alluded to, is because the way plant hormones work, the tree will start "cropping" -- i.e. Fruiting -- at an earlier age and produce more, too. It also makes it much easier to harvest from lower hanging branches. My semi-standard Enterprise is trained that way -- sometimes it's better to bend the branch over than to cut.
I noticed that this tree is rather close to the walls as well -- does that mean there is limited amount of sunlight? I was wondering why there is a sofa next to it....?
Assuming this is a good location for growing the apple tree, you might look into pruning and training the tree as an espalier. You would provide wire and cane supports for the branches so they can grow longer without sagging. This will enable restricting the tree's growth and size to fit a compact space.
Let's see if I can find a recent photo of mine (though mine pruning and training results are far from good examples
...maybe this one with the cardinal...
Looks like the last time I took closer photos was back in the beginning of the month:
...persimmons, apples, and pears...
