I agree with Hugh re supervision plus by the time the extension is built your son will be nearing an age where he understands a little more. You may also want him in there to cook with you soon. I'm sure the kitchen can be designed from a safety aspect too if that's the only thing holding you back. I think the advantage of using OnePlan is that Karen can look at the whole house spatially etc and you're not tied to a particular kitchen company (I'm not on commission!). Click on her profile for reviews etc. I second Hugh's comments re karndean too! I like the heringbone parquet! If you did want to hire an interior designer (designers tend to be qualified in planning too I think as opposed to an interior decorator although many of those could be qualified by experience) then you could find you save as much as you spend. Some of them will offer you their trade discount which if doing the whole house could add up to an awful lot. They may also make you save from any mistakes and I've made a few of those! I'd go on houzz and search for pros and look at their reviews and previous work. I think you need to meet people yourself though as it's important to have a good working relationship and make sure they understand you

I had a ushaped kitchen with peninsula in previous house as no room for island. I never felt stuck behind it- in fact i liked the fact that guests and kids were more likely to stay on the dining side out of my way! I now have an island as I'm stuck with the kitchen in the house we bought, and it drives me a bit crazy when there are lots of people in the kitchen as they all gather around the island and get in the way! I think your plan is pretty good except for oven position. I think it's really far from your workspace, and also I'd question the wisdom of having the oven beside the fridge? Maybe a tall larder cupboard in this position, and a range style cooker with double oven beneath? Or move the hob to the peninsula and put double oven somewhere along that wall?

Hello! Wow! Thank you very much for your advice. So, there is a radiator on the right hand wall. That is where current owners put their tv. Not sure it will fit, will measure up soon hopefully. The TV could go on a smaller unit to be honest, and will make sure radiator is turned down! Just worried that there isn't enough room for a corner sofa there with the door to the hallway..(see photos on rightmove) I LOVE the idea of large mirrors either side of fireplace. Pinching that! ;) My current living room is decorated in shades of greys and lots of gold. Thinking of going navy and gold but not too sure. Sofa colours argh! Huge thanks I'm very grateful. Katie

Here the layout as it is now
