As the nights close in, how can I get more light into my home?

Builder Kieran McCarthy on how to introduce extra daylight into an east facing semi-d kitchen

Light from the South is the holy grail of daylight orientation so this is where you should focus.

Dear Kieran,

I live in a semi-d where part of the kitchen is jutting out into the back garden and has a slanting, tiled roof. The only window is over the kitchen sink, which directly overlooks the east-facing garden.
