Hi. I think a lot depends on budget as you don't have any beds so could spend a fortune on planters! ideally I would add planting all around like this image from garden builders. However assuming you're on some form of budget I would add either 3 spheres to the lawn area or one large one. I would invest in a large potted olive maybe 8ft and place in one of the back corners. 3 large planters ( this one is from primrose

) central on the back fence and add artifical topiary box plants. Palms also do well in pots and can be comparatively cheap for a large plant but look for a hardy one so its maintenance free and put it in the opposite corner. Maybe have either one of the bench seats with plant boxes either side to put along one side of the garden or a curved stone bench and have some form of seating table arrangement on the patio outside the door. If/when budget allows I'd add a couple of long troughs either side of the garden and add plants/small trees of different sizes plus a couple of potted large plants either side of the corner of the house

Soften it with pots of flowers and small trees .

For plants - you could have some beautiful Japanese Maples, Herbs and Vegetables, Exotic Palms, some complimentary Hedging, Fruit Trees, Exotic Bamboo, Roses, Ornamental Treesor even Bay Trees!

Or possibly awnings, garden furniture, water features and heaters for some quality outdoor living :)

Hi Cchauhan,

Firstly we don't copy and paste our comments from other threads, so what we write is strictly for you:)

Do you want to include some plants in the garden? There are many plants that are evergreen and require almost zero care.

How would you like to change the garden?

Do you like to look back at your house or would you like the central area to be a little more enclosed and private?
