Is there much natural lighting in the bathroom? I would be templated to go with a full-height mirror (i.e. to the ceiling) in order to maximise light, although it would be a shame to cover up the full height tiles which you have paid for. Is there anything about your current bathroom mirror that you particularly like or dislike? Do you find that you fight for mirror space with your partner, in which case, two separate, small mirrors may not be ideal.

Be aware that artificial turf can get very hot underfoot. You could lay a narrow old brick or limestone paver path to clothes line for easy access and plant ground covers or low profile herbs (eg.oregano and thyme) to use in cooking. Hardy herbs or flowers such as rosemary, lavender, geraniums against the edges of the space toward the back. Even add some large long troughs of flowers on the retaining wall to pretty up the area. It looks like it could get quite warm there but maybe a jasmine or similar climber to climb up a frame attached to the part of the large wall where there is no clothes line. Good luck, it will be a lovely space I'm sure once you get started.

Hi there, I think it's a great idea to introduce some feature lighting here. The chairs are making quite a statement against all the white and it would be lovely to balance that a little with lighting. As you have a lot of white and also rectilinear shapes, I'd lean towards organic shapes and materials for your lights. You could consider having more than one pendant light and create either a cluster, a row of 3, or else a long light. Here's some ideas.

I can understand the frustration at the thought of obscuring the sliding doors. To avoid that you might consider a pair of sofas that face each other. (Like in the picture attached) This position looks very welcoming as it invites the seated people to face each other for conversation. It does mean for viewing the tv on the 'blank wall' you won't be in the most comfortable position, so I suspect you'll need to compromise somewhere... Access to the door against tv viewing.
