Would love to help, but you need to provide a lot more details and pictures.

I would choose my conservatory as it is peaceful, clutter free and full of light. also lovely and warm so you can go for a Wee sleep.

The "L' shape which extends further on the right will give you marginally more light into it - but this depends on the design of the roof and glazing - which is vitally important to the end result. I would consider putting pocket doors from the lounge into the kitchen (keeping the size as is) to allow the afternoon sun to be seen from the kitchen. This space might be a better option for the playroom - depending on the age of your children etc. I would put kitchen on the right hand side. Could you put a door from hall into the bike store so you don't have to go through the kitchen? Consolation prize for this orientation is that the back right hand side of your rear garden will hold the Summer evening sun the longest - so thats where to put the BBQ!

Gosh..Who knew this could be so difficult. We would love your thoughts on our remodel exterior facade on color (any color other than white, beige or gray..if possible). Also we love the look of Nu Cedar as it looks like real cedar, but if paint it, wouldn't it look monochromic anyway? Would you advice to paint after installation if we go with James Hardie. The 2 Facades are below...#1 or #2? facade #1 facade #2
