You're really looking at either a hi end kitchen company who supply a more traditional style kitchen ie inframe, or as @Daisy England says, go to an independent, but as you're planning on having this sitting on your worktop, depending on the design of the rest of the kitchen ie if you have towers, the counter level bi fold doors would be to a special size (as most tall doors are designed for tower use). The easiest way to do this would be to have an extra wide larder (800 or 900), fit an internal drawer unit at the bottom, then a piece of worktop, have power points inside and 2 or 3 shelves above. Depending on where the doors come from it may 2x 1965 doors or 2x 1245 doors at the top and 2x 715 doors at the bottom, all standard stuff. Bearing in mind the appliances your trying to hide would be too big to fit inside a 'standard' 300 deep dresser type unit, the counter top option might not be the most suitable. But for a budget of 20K, i could design and supply a larger than average kitchen that has some bespoke made to measure doors and specially designed rigid cabinets and all to a high spec.

Daisy, that was my experience before and my builder didn’t have a trade account so we didn’t get a Howden kitchen, which is what I wanted. Magnet did a great job and my builder did have an account with them. I have yet to contact a joiner. Chris, I might visit all the kitchen people and see clearance stuff they might have. I really wanted some pictures of real London houses with a pantry in small kitchen like yours. Not the American dream kitchen or in a Surrey mansion. Thank you for all your ideas and advice.

Hi, Thank you for sharing your renovation plans; it sounds like you’re creating a wonderful, functional home! Including a utility room and possibly a pantry is a smart idea. Utility Room Ideas: Placing it to the left of the kitchen works well. To avoid that long corridor feeling, consider pocket doors or frosted glass for the patio doors to keep them light and open. In a compact utility (2 x 1.5 m), stackable appliances can save space. Add tall cabinets for cleaning essentials and a countertop with shelves or pull-out drawers above. Pantry Ideas: A walk-in mini-pantry could work even in a small area (as little as 1.2 x 1.5 m). Open shelving on three sides, a counter for small appliances, and vertical storage for trays would make it super functional. If space is tight, tall cabinetry integrated into the kitchen design can still provide great storage. To Keep It Seamless: Use consistent flooring to avoid breaking up the flow, and add light through windows or recessed lighting to make the space feel open. A feature wall or divider could also help break up the corridor visually. Would you like me to sketch a few layout options or help select finishes? Let’s make this space both beautiful and practical.
