Nutcutlet I agree with your choice. I planted Rosa glauca last Autumn. I had one in a garden years ago and have always missed it. Finally found it at a rose specialists.
Agree with Goldi about thinking of shrubs instead. Even if you got the low height it would probably have a wide spread. The RHS list of small trees starts with Amelanchier Ballerina at 4m-8m.
I'd also recommend Viburnum bodnantse spp. They can grow to 3 - 4m but can be prunded. They flower through the winter, with the leaves giving privacy in the summer
