Help me make a start on my garden? - diagram included

[sparklins]

Moved a bit ago but not touched the outside yet bar from a bit of tidying.
The diagram is of my front garden and driveway which is significantly larger than the back the drive will very comfortably fit about 3 cars in a row for scale. Where the hedge will go is the roadside.

The flowering shrubs I cannot ID are woody if it helps. All the shrubs are around 3-4 feet tall.
The 2 wisteria have been tangled up in the overgrowth which was in and around the whole border, they look like they have been planted and left there, some vines are 11ft long and I am planning on running it on the terrace wall it sits at the base of.

I would love any advice on what to plant where, I would really like lots of perennials and hardy shrubs as well as maybe some seasonal bulbs like tulips and daffodils. Easy maintenance would be a bonus.

I'm not sure what to put where and what time of year to plant what. I can start in the garden anytime now that the inside is done so feel free to spam me with ideas. 😊

What’s the approx measurements? Is the green rectangle lawn, and do you want to keep it as lawn?

I would dig out the bamboo first tbh before it becomes a nuisance 😩

I would get rid of the lawn and do a prairie type planting.

Lots of grasses (stipa, miscanthus) rudbeckias, helianthemums, that kind of thing.

The lawn aka green rectangle is definitely staying as it's the only flat surface we have the back is tiered and much smaller so the kids play at the front in the summer.
Whats wrong with bamboo?

Not 100% on measurements I would say the length is approx 50ft the edges where the plants are are around 3ft maybe. Really struggling to guess how wide the lawn area is maybe 19ft or so?

Ah that’s a good reason to keep it as lawn!

Bamboo - even the ones sold as non invasive - can spread rampantly eventually. We inherited a clumping bamboo in our garden and ended up having to dig half the garden up to eliminate the spreading rhizomes. It’s just not worth the bother imo unless you have it in a container. If you like the bamboo vibe, a large ornamental grass like miscanthus would be a good alternative.
