When we moved into our new house, there were two sheds in the back of the garden painted in green and brown.
I used cream garden paint to update the look of both houses and make them look alike. The look of the windows have been improved too by adding strips of wood as window bars mimicking the look of Georgian bar windows.
The same type of paint has been used to paint the inside of the old fish pond making it a sitting area (see different post). By using the same shades of paint the overall look of the garden has now drastically changed. I might paint the shed doors in a different shade for example grey to set them off and let the houses even stand out more. What do you think?
