Getting small garden in terraced house landscapeded, I'd love a cottage style , what do I ask for?

[Starzinhereyes]

We are getting our garden properly landscaped in the summer. We have a good sized patio, a patch of grass which we are replacing with artificial as the drainage is terrible & we have dogs... We are getting a pergola on the patio... Would love some high beds to plant shrubs & flowers, they need to be high to keep our little dogs out.
I love seeing the birds come into the garden so would love a feature to entice them in.. Our budget is 7k.. I'd like it to look very neat but the cottage style natural & unstructured..
Any suggestions as to what to ask for or what accessories to buy would be greatly appreciated!

Same garden when I was much fitter to maintain it.

Can anyone recommend small trees/tall shrubs to achieve this look?

florentina that is stunning, I love your planting.

@anyoldtime small trees
Dwarf Robinia, either Frida with yellow racemes or casque rouge which is pink
Sorbs cashmiriana
Cotoneaster
Amelanchier
Acer Griseum
Prunus little pink perfection

I have all of these in my small garden.

florentina1 Thank you.

Dwarf Robinia is frisa not frida

A word of caution about flowering cherry trees. They have vigorous roots - mine forced its way into the main sewer from the house and blocked it completely. £3000 to dig up and replace the whole length of sewer with rootproof drains, and £300 to fell the cherry tree. Which,despite poisoning the stump, still throws up suckers twenty feet away. I’d avoid them in a small garden, unless you can get a dwarf one in a pot.
Also, although the blossom is gorgeous for two weeks of the year, it’s just dull and overshadowing for the remaining 50!
