Hi Lloyd_nicky,

There is a lot to consider when drawing up lighting plans.. and there are some standards you can work by.

It matters which lights you go for and the colour of light (white, warm, daylight) and their output. We calculate this using the BTU's that are required for each area. You can find only calculators fairly easy on google. This may help getting a number to start with. You also include any under cupboard lights etc (lamps too although these are not drawn on lighting plans).

For placement. In a kitchen you are looking for the spots to have 1m around before meeting another light. 500/600 before meeting a wall. In the dining and living area this can be further apart (depending on the lights you go for). Always think about what shadows will be cast by the lights above or behind you when working at a counter-top and try to ensure you have the surface directly in front of you lit to counteract the high spots.

I hope this has some helpful tips for ensuring your plan works for you. The last step is then to ensure you have enough circuits which don't seem to be shown on the plan. I would be looking for a minimum of three in that space (all at least two way) depending on how you use the space.

If you are still unsure, there are companies who specialise in drawing up these plans or you can ask an interior design or concept planner (like me) who offer lighting and socket plans as a separate package. Lighting being one of things not easily changed later - it's really important to get it right first time.

All the best with your project. Gina
