Here are a bunch of paint samples, the large blue portion with white siding is the house behind me. Backyard is the next project.
Should I paint the house before or after landscaping?
Thanks in advance!

That neighbor's blue is a cool color without a yellow undertone. Your small blue samples are warm blue. They don't go together, imo. I don't like your neighbor's blue.

Just a note about the Ceanothus. They are shrubs really and to make one into a tree will require some pruning and training. And it will still not be much more than 8' tall. There will not be enough clear height to avoid poking people in the face when they walk past your house. Look how broad the tops are in your pictures. But you could train one against the house wall. This one's near me. Note how low it grows over the sidewalk.

Floraluk2, it’s soooo pretty!!! I’ve seen it as a sidewalk tree in other parts of the city. I’m prepared to train and prune, plus I can’t have anything too tall- don’t want to block the neighbors ocean view.

Do you have other colorful tree/shrub suggestions?

They are certainly very pretty. But I'd still be worried about poking passers by. Or doesn't anyone walk in your neighbourhood? I don't drive and I find overhanging shrubbery infuriating ... and I have good eyesight. It's a nightmare for people who don't. I would put them in your front garden, not in the sidewalk. For people to give alternative suggestions they need to know your geographical location.

There’s plenty of foot traffic in my neighborhood and I’m pretty considerate. My goal is to have something beautiful for everyone to enjoy rather than be an inconvenience so I’m open to other options. I was also looking at the Tibouchina (princess flower).

Simplynatural, wow, what a difference! One little feature you added that I really love is the nook for the compost bin! I also love how the taller trees really bring the eye up. I’m not a huge fan of cypress but I’m sure I can find something else. Thank you for sharing your vision!

Some option for landscape

Celery, love the addition of the walking path and pops of color! Thank you for your ideas! The second house definitely looks like it’s from my neighborhood. I’ll keep an eye out for it.
