Our kitchen is quite small and leads off another room which we call 'the breakfast room' - that's where we put a table, chairs, have space for artwork, the dog's crate, a cupboard for glassware. Other houses might call the space a kitchen diner, but we have a separate dining room.The table is extremely useful for when I"m preparing a monster meal for entertaining a big group in the dining room, as I don't have a lot of sworkspace in the kitchen itself.
What I do like about our small kitchen is the efficient 'triangle' of workspace, oven, sink, dishwasher and fridge. I can be proper cheffy in that space - I hate a pointlessly large kitchen where you have to take several strides to get from oven to kitchen or workspace. The entrance from the breakfast room bit is quite narrow, and to save space the floor to ceiling cupboards are divided vertically, so you can fold the doors back when you open them.
We didn't design or install this kitchen and I think our predecessors did well in a small space. What I wouldn't do is skimp (as they did) on the extraction system - it's a recirculation extractor hob - I guess they thought, small room, can open the door to supplement it. It's OK, but not brilliant, and I miss having a proper external ducting system. We also installed better under counter lighting, with a dimmer system. The previous ones were a bit pants. I also added those shelving units that rotate to make the corner units more accessible. I'd like proper bin storage, but there isn't really space. But overall, it's a decent kitchen, which has held up well, still looks good and I can't complain!
In a few years time, we'll do a side-infill extension to incorporate the former outside lav, currently a tool shed and expand the space and light somewhat. Still won't be huge by some people's standards, and I'll want to hang onto the compact, efficient working area, but that's when we'll address the deficiencies of the current design. That will be our 'love it or list it' moment.
