Hi Fresh Kid, I'm a researcher with Openlight, a new startup looking to change the way homeowners buy and install windows in their home. We're at the very early stages of our business and looking to chat with people like you to learn more about your experiences and what can be improved. Would you be willing to have a conversation with us? Let me know and we can figure out the best way to get in touch. Thank you for your time and help!

Hi. I would talk to your builder first and let him know what your vision is. He will give you feedback on any potential issues/things to consider, You can ask him if he is able to co-ordinate other trades people. If you get the right builder they will work alongside you to project manage it. You may need a structural engineer to provide advice if your removing any internal walls, depending whats the walls are and what is above that might need supporting. So i would get this advice early as it could impact on your layout kitchen design. If they are stud walls and not supporting anything your builder will let you know and be able to take these down. I would then chose my kitchen and get a design drawn up - most kitchen companies do this as part of their quote process. You can see then if the layout you would like works is the space you have. Lots do the installation also which can be helpful. Lots have a lead in time of around 12 weeks from order - some builders merchants have a small range in their stores if you wanted it quicker. If its an older house you might have some asbestos containing materials - sometimes in old floor tiles, that you need to be careful how these are dealt with/removed. The HSE has helpful info. Check this before your start any strip out/demolition. Once thats done, there might be some ceilings to make good where you have removed walls, which would be best done before your kitchen goes in. With your new island you will need an electrician, who will probably need to move socket points in the existing kitchen area depending on your new kitchen layout and to then wire in appliances. They might need to be in several times doing a first and then 2nd fix. Once the kitchen is part way in i then organise my tiles as i can see exactly what area i need to tile. If your using floor tiles, you can tile to just underneath the units and your plinth then hides the join. You could tile right the way under but that costs more and no one see it!. Decoration usually comes last. I find its best to keep talking to the builder and if you have the right one they will help you through the process. Good luck with your project.

You can get blinds that clip into the upvc window seals that could be effective here in the awkward space. Lots of places sell them. Not the most attractive but they d the job :) https://www.blindsdirect.co.uk/perfect-fit-blinds?gclid=Cj0KCQjwi7yCBhDJARIsAMWFScOOvl0wjY6YJjqrSY36htfwui-z_qtOKBDtqV__gAWxEXAQj6rNw0IaAhivEALw_wcB 

I ordered French doors for an extension from architects drawings and had no problems. They were a good company and the doors went in perfectly. If you wait till the building is done you will not be able to progress with the rest of the work till the doors/ windows are in place.
