Olive Tree

I absolutely love this tree. It is larger in width that I expected & would have liked it to not have been as wide. However we have kept it & eventually I’ll buy a less wide olive tree for the position I have & will use this one in a larger space. It is beautiful & worth keeping.
The pot isn’t a pure white, which again I would have preferred. As you can see from the photos it looks good regardless of my preferences.

Great table for small spaces.

Looked high and low for an adaptable dining table that would fit into a small space. It's really clever and neat the way I can extend the table if needed. Found HOI really efficient at both the ordering and arranging delivery. Would definitely use them again without any hesitation.
