This is a handsome house. First...symmetry. Can you make the front pillars the same height. I would lower the LH one to match RH. A strong iron railing along the LH side and in the small front piece LH. Keep front door a strong colour....dark green/blue, navy, whatever, and paint the iron railigs the same colout. Avoid lots of small pots...messy and lots to water. You could i) have a narrow raised bed along the RH wall between you and the next property planted with a mix of small evergreen shrubs and trailing plants..small Choysia Ternata, etc., There is a trailing euphorbia (Amagloides ?) which is sculptural but relaxed. ii) Acquire or have built two or three large tree pots. When they are empty, position them in various places, with bamboo canes, to see where they would work best, and how many you want. I would suggest something deciduous with autumn colour and blossom, like a prunus autumnalis; a crab apple; a quince on dwarf stock; a columnar flowering cherry,Prunus Amanogawa....the choice is huge. Avoid cottagey annuals and too much patchy, mixed planting. I would keep pots square, in harmony with the raised bed. This house is formal and urban. Keeo it elegant and with strong lines broken by the foliage and trailers. I needs beauty, not prettiness. cheers

I agree, try and add some grass, a few easy to maintain shrubs, and a little fence or wall around it so it doesn't look like your in the middle of a car park. Might be worth replacing or updating the fence on the right too. Keep the drive just big enough for the cars you're parking. Our neighbour had some resin laid, looked great a first but looks a bit tired now. We went with Beamish cobble in a charcoal colour which has aged well and I think would suit your property

I think we probably need some photos and/or sketches to answer the question, including where you're thinking of putting sofas etc?

E D, not really, hahaha! I simply used what was there. The brickwork and the color are off, rosemonde's sleek square bay windows would look a LOT nicer. The front door and the windows next to it are way too cottage-y. And the slope on the little roof on the right should be steeper, so it lines up better with the balcony side of the house. But I do like the bones of it, so to speak.
