Why not think about adding an actual outdoor room to your yard? Enabling you to spend more time out there, whatever the weather, erecting a tent or trellis with a roof, is a useful and stylish addition to the garden. If you have a lot of space to fill this can also help divide the garden up into more manageable sections.
You could plant flowers and plants around it to ground it in the space, with climbing plants being a great option to help it blend in as time goes on. If you want to go the whole nine yards with the whole outdoor room thing, then you can put in a comfortable bench seat, or some Moroccan-style floor cushions, with lanterns and a low table. You’ll never want to leave.
