Personally I think you need to bin the idea to put the kitchen there because it divides the space in such a way that there are four areas that have no apparent purpose and are not really big enough to do anything with. I suggest you blank out the kitchen cabinet position and the utility room on the plan and give the blank space to a kitchen professional to show where they would put the cabinets.

@kazzh Adding a wall as suggested by HU won't allow for the intention of an open plan with the living room as and adding a wall by the current opening will remove a lot of afternoon light from the living room. Adding the laundry to the pantry is certainly possible, it's an idea that has been considered, but we didn't know a) how possible it was to create a new waste pipe and where to run to, possibly the bathroom next door. b) how to position the pantry area to consider a reduced length of waste pipe to avoid a mass of disruption of other units ie cutting holes in them. Moving the patio door isn't impossible, as we can just brick up the current and add a window, then add a patio door to the extension. Thank you so much so far!

Hi, Extending your kitchen into the dining room to create a kitchen diner is a great way to open up the space and improve functionality. Consider the layout to ensure smooth flow between the two areas, possibly incorporating an island or breakfast bar to divide the space. Lighting is key, so use a mix of task and ambient lighting, along with natural light through windows or doors. Ensure design cohesion by choosing complementary flooring, cabinetry, and colours across both areas. Thoughtful storage solutions, such as built-in cabinetry or a sideboard, can help maximise space. Be sure to budget for structural work and check for necessary permits to comply with regulations. A kitchen-diner extension offers more room for cooking, dining, and socialising, enhancing both the functionality and feel of your home.

If your garden is a decent size I would consider replacing the conservatory with a full length extension of the same depth. This is also budget dependent. You could then have a fabulous kitchen diner and probably a tv or entertaining area too.
