I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

I agree with havingfun, thicken the supports and have something growing trailing up them. I didn't even notice there was a pergola until the close up. Right now it blends in too well with the house color, consider painting it a different color. I don't know your usda zone but classic climbers for a pergola include clematis, wisteria, grape https://www.houzz.com/photos/santa-ynez-valley-mediterranean-porch-santa-barbara-phvw-vp~2485412 or go for a modern look You can also hang string lights, planters or something from the beams. Also agree lighten the front door.

Here’s one drawer in our showroom. Only use the best.

I got some custom made linen curtains installed yesterday which I was really excited about. On closer inspection I noticed that they are quite uneven at the bottom: on the sides of the windows they just float over the carpet which is what I requested, however, towards the middle they are about 3cm off the ground. The curtains are on a double track with the lining being able to be pulled across at night time and the lining is floor length and shows slightly at the bottom where the linen sheers are shorter. I was wondering if anyone here can give me some advice on whether I should request them to be adjusted or is it acceptable to have a length difference of about 2cm from sides to middle? I also feel the middle looks too short. I am paying a lot of money to get them custom made so I feel they should be perfect, right? Looking forward to your opinions and advice.
