"Trees" in question look like camellias, which are really large growing shrubs that are often pruned into a tree-like shape.

The one right in front of the entry stoop looks like it was not sited very well so you may want to think about relocation for that plant.

Removal or not is really your decision. But these are extremely common, shade loving evergreen shrubs well suited to warmer climates. And they should bloom if given the proper growing conditions.

The camellias have been allowed to get leggy; they can be judiciously pruned and shaped. But the one in front of the door is just poorly sited. I wonder if it could be moved?

I would first prune the camellia between the windows and give it a chance. I would remove the big blob sheared shrub along the walk. Perhaps the offending camellia in front of the door could be placed out a bit from the walk in that area where it will still be shaded. Plant a massing of shade-happy foliage plants (low-growing) in the bed along the walk, but not so close that they will interfere with walking. Mulch heavily with natural, undyed organic material. If the camellia is not worth moving, select a tree or trained shrub that will not exceed 30 ft. in height at maturity, and will not spread up against the house. A Bismarckia nobilis would make quite a statement.

IMO, it's extremely weird that there is no walkway from the sidewalk directly to the front door - if that is indeed the front door? It almost looks as though it's a side door that connects to another entrance via that walkway. Does the walkway lead to the driveway/garage? Is there ever a reason for them to walk directly out the door and out to the street?

Anyway, I agree with Yaardvark that none of these plants do anything for this landscape. His/her drawing represents a drastic improvement to the look of the house. Personally, I would add a path to the sidewalk as well!

Tree shown close up looks like a Photinia.

Definitely not a Photinia. Size, veining, and thickness of leaf as well as stems, bark, and general habit conform to Camellia, though I can see why you might have thought Photinia. Completely absent the characteristic red new growth of Photinia.

That was my first thought, too ... photinia. There are a few copper and red leaves on it. But I think Kate has gone so it might not matter what it is.

Sorry cannot agree with Camellia at all, this is instead definitely quite like Photinia.

Well, now Embothrium has said it, I'll say I was also sceptical about the Camellia id but wasn't confident enough to mention it. The top picture especially looks wrong.

No, I am still here.

Thanks guys for your all suggestions replies. To be honest I am more on the side of Photinia than on Camelia. It is hard to say, they have never saw any blooming on those trees and leaves do look red . But in any case I think they will keep those trees for now, they will trim but that bush (as kiminpl called blob) they probably will remove it and plant small tree as Yardvaark(9A) mentioned. Yardvaark(9A) Thanks for your design and suggestions. We like the idea of multi-trunk tree in front of the blank wall. As biondanonima said it is weird layout. The walkway leads to the driveway/garage that's correct. So thats why there are no reason for them to walk directly out the door and out to the street. And that's why they don't need walkway from the sidewalk directly to the front door. So the idea is to make this entrance more closed from the public. To plant plants in order cover the ugly layout and huge wall, make some privacy. Because the entrance is facing the main road and it is a corner house.

There are used to be two huge oak trees in front of the house. When they moved in they had to cut it because they were dead. Thats why that wall look very weird.

Here is the picture from 2008.

Here is the picture from 2016, you still can see sign on the grass from oak trees

I probably should have mention that this is corner house and facing main road. But the real entrance leads from driveway.

One more picture:

In spite of the fact that the public does not need to access this entrance, it is important in that it is one of the few interesting/attractive architectural details at this face of the building. On that account it ought to be made attractive and visible, not obscured. Making it attractive does not mean make it look like the public should start using it. Access is still roundabout.

The small trees, most of all, work to do really bad things to the building setting. Regardless if they were to develop any positive features themselves, on account of their placement and their character, there's still nothing they contribute in a positive way.

Oh, I hate it when I am so damn wrong!

Was a reasonable conclusion that had me doubting a bit. So much for the imperfect science of picture ID.

Yardvaark(9A) we love your design, you made us think twice. We will take your advice regarding cutting trees into serious consideration.

By the way I took new pictures from the trees this weekend.

Scarlet maple for sure. :-)

Taking Yardvaark's image with the tree on the right and the plantings on the left, I'd add the following ideas. I'd widen the path as Yardvaark suggested and continue it along the foundation to the area of the house, that looks like a screened in porch. It depends, if the walkway stays solid like concrete or becomes fenestrated like stepping stones. I'd then extend the whole planting along that wall, encompassing the tree planting. Then the area next to the house becomes a narrow court yard of sorts along that whole side, and the home becomes tucked in a little bit. The windows between the screened porch and the entry way could have a garden to look into. Another idea I had along the tall windowless wall, was an espalier tree planting. Not up against the house, set out from the walk so there was room for walking between the house and the planting.

Yardvaark(9A) but all leaves are not red, just some. Maybe it is Photinia?

Thanks enduring(5a), we will keep your suggestions in mind.

I will post in few months the final result.

"... but all leaves are not red ..." and that's how Photinia is. New growth is red. Old is green.
