First decide is it necessary as the feature of a step down doesn't necessarily detract from the room, often enhancing it !

Split level might be an option but I was rather concerned that we might end up with being restricted on what goes where based on the available area of each section. Again, there are not many photos on Houzz if split level patios (although as arc3d demonstrated there are rather more of decking). Different options are going to cost differently but would rather have something that works than the cheapest option. I don't think there is enough slope on the garden for it to be hidden behind a higher patio. Some of the height is just because the original house was built up a bit. from ground level.

Hello, It sounds like you have some great and really exciting ideas to make your home an even better fit for your family. An open plan kitchen dining room would be a great way of boosting family space and allowing the layout to feel more open and spacious. Bi fold doors looking out to the garden would be a great way of boosting light in the space - you could look at having the kitchen/dining room in the reception room looking out into the garden. Have any of your neighbours successfully had an extension? From the plan you do have space to play with, without having to extend. It may just involve making a few internal alterations and looking at what you currently have that does work and what doesn't work. There's lots of ways to maximise kitchen storage, from having drawers that you can stack fully meaning no wasted space, to tall wall units and pantry units that are specifically a food cupboard. I hope this helps give you some more ideas and possible things to consider. If you would like any design and layout help with the kitchen/dining room then please do let me know as we have plenty of options from just starting out on brainstorming layout ideas to a full bespoke design. All the best, Charlie www.coveykitchens.co.uk

Thank you all for your comments and feedback - From the feedback seems that the benefits of having a flush transition to the exterior space outweighs the disadvantage of the big drop at the end. In terms of the steps, as the garden is small and not very deep wide steps from the end of the patio would take up too much space so I was thinking of using recessed steps (see image) - it reduces the usable patio space but keeps the garden area.
