Dear Ocean and Lynn, I'm happy to help property owners if I think I can give a helpful, concise answer or point them in the right direction. Although this is a valid design dilemma, it is one of several types of question that I should think many professionals on Houzz will avoid. This is a technical query which requires detailed knowledge of specific products and circumstances, in which giving inadequately informed advice could be problematic. These are usually best addressed to manufacturers of specific products or an architect / designer / installer who is engaged to deal with the project.

<?xml version="1.0" encoding="UTF-8"?><md>Thanks one plan, I had thought about a panel blind but they all seem to be 60cm wide which is too wide. The barn door might work, I just have 2.75cm clearance at the top so will need to research. At no 19. I’ll look at those.. Here are photos of the area, I don’t want anything covering the view during the day, just black out at night. Thanks everyone for your comments, really really useful. I’ll post the outcome...might mean wearing a blackout eye mask

Good Morning Ranj, This is an exciting project, it has plenty of potential. I think you would benefit from hiring an interior designer who can look at all of your options and come up with something really innovative. The safe option is to go with one level, however the different levels can be fabulous for sunken seating or transitioning from an island to a table height. Different levels can be navigated safely when planned by an expert and they can add depth, interest, wow factor and more. I would love to help you and invite you to visit our page. Interior design can prove to be a great choice not only ensuring that your interior is a heaven for you but also through ease of the process, communication, project management and passing on trade discounts to you. We are happy to work remotely and can still visit site with precautionary measures in place for the current situation. We cover Cheshire and Wirral. Many thanks, Sophie Ellen Utley Interiors

Thanks Saara and Eerospace. There are existing pipes at the rear; the original separate WC (to be converted along with a cuboard and landing area, into a 4th bedroom) and the bathroom (to be reduced in size so the rear ensuite can be created following a chimney removal). There are no existing pipes for the front ensuite and will have to be laid along joists under a bedroom and out at the side of the house. The plans were drawn up by the architect so I didn't question sizes of rooms at the time as I supposed they would be suitable. Eerospace - I'll drop you an email thanks. Happy to do the same Saara.
