We have a north facing garden that is actually quite sunny beyond the for 2.5m from the house. We have large glazed doors at the back and also sky lights so despite being north facing it gets a reasonable amount of light. We are quite overlooked though and were thinking of installing a pergola on the patio as a screen.
As the patio is already shaded do you think this would reduce light into the house or it would be fairly neutral. We are thinking it would be a slatted roof in any event with some plants growing on it.
