Positioning the sink poorly

I don’t believe in design regrets but I do believe in strong decisions. One of the biggest? Whether the island should house the sink or the hob. For family homes, I almost always choose the sink. Yes, it can attract clutter but only if it’s poorly planned. The key is positioning the dishwasher directly next to it, so plates can be scraped and loaded in one seamless movement. No crossing the kitchen with dripping dishes, no visual chaos. I would only do this if there’s a separate utility room nearby for larger pots and heavier mess. That’s what keeps the island feeling social and beautiful rather than functional and frantic. A hob on the island might feel social for the chef in the family, but I really struggle with ceiling extractors interrupting sight lines along with less prep space and the odd splashes of hot oil.

Creating an appliance graveyard

Worktops cluttered with coffee machines, toasters and air fryers instantly dilute even the most beautiful cabinetry. We always design in a larder cupboard with pocket doors to house smaller appliances – doors that can be closed in seconds when guests arrive. We’re also using fewer kettles thanks to hot taps, which genuinely are a game changer. But the principle remains: surfaces should feel intentional, not storage-led. A kitchen should feel curated and effortless, less like a showroom for countertop gadgets.

Avoiding marble countertops

I will always advocate for marble worktops. We design for lifestyle, not laboratory conditions. Marble is an organic material that ages beautifully; subtle etching and patina tell a story. They are not flaws, they’re signs of life. If you want something that looks identical in 15 years’ time, choose a manmade surface. But if you want warmth, depth and quiet luxury, marble is incomparable.

Installing runway downlights

If there’s one area people consistently underestimate, it’s lighting. A single row of downlights will never create the right atmosphere. Layered lighting is essential: ambient lighting for warmth, task lighting where you prep and cook, and decorative lighting to anchor the space. I often use discreet recessed downlights or minimal surface-mounted spots, always on dimmers.

Keeping your hob & sink far apart

Always keep the hob and sink on the same side of the kitchen. It could be a pain having to walk from one side of the kitchen to another, navigating children and pets with a pan of boiling water to pour the water away.

Building in gadgets

Really think, how often will you use the latest fad and do you want to build built-in cabinetry around it? There’s no doubt that organised and dedicated storage and appliances make daily life easier but equally, using up space and budget for things you don’t or won’t use is a waste.

Placing the fridge in a high-traffic zone

In busy family kitchens, this quickly becomes frustrating with people constantly blocking walkways and doors swinging into main circulation paths. As a general rule, fridges perform best at the end of cabinetry runs, not in the middle of the action. If a fridge does sit mid-run opposite an island, a two-door configuration can help reduce clearance issues, but be mindful that this often sacrifices valuable internal door storage. Which leads onto fridge storage. People often don’t pay enough attention to the amount of fridge space they require. Think about the contents of your fridge and where you like to store items, i.e. what sort of volumes do you drink your milk in, and how much space will this take up in the drawer? Given a choice, our go-to solution is a large 91cm single-door Gaggenau fridge placed at the end of a run for maximum usability and longevity.

Putting the cutlery drawer under the hob

Placing a cutlery drawer directly beneath a hob is a layout shortcut we strongly advise against. While slimline drawers make it tempting, it creates poor workflow and daily frustration. Good kitchen design prioritises natural movement and ergonomic flow, not just squeezing elements into available space.

Wasting island storage

The back of your island is premium real estate. Too often we see island backs fully boxed in, which is a missed opportunity for valuable storage. This space is ideal for items that don’t need daily access, such as serving ware, bulk appliances or entertaining pieces. We do recommend avoiding push-catch or sliding doors here. They tend to be awkward to use and don’t hold up well over time.  

Hanging glass pendants over hob islands

Glass pendants over an island hob may look beautiful but from a practical standpoint, they’re a regret waiting to happen. Even with high-performance downdraft extractors, grease and cooking residue will settle on the glass creating constant cleaning headaches. If the trend for track lighting isn't your vibe, then a single statement pendant hung over one end of the island, ideally at the dining end, is our preference. 

Holding back on task lighting

Another common post-install regret is insufficient task lighting. Prep areas need strong, functional illumination that can be switched independently from ambient lighting. If you can’t clearly see what you’re chopping, cooking or plating, the lighting design has failed, no matter how beautiful the fixtures are.

Installing a cooker on the island

Small extraction hoods from the ceiling look out of place and don’t work well because of their distance from the cooker. Also, the extra clearance needed on all sides of a range cooker breaks up the continuity in an island. We like to put our islands on legs so they look like one piece of furniture. Don’t get us wrong, we love a range cooker, but it should go against a wall with a beautiful canopy extractor sitting above it. 

Cutting back on appliances

If space and budget allow, you will never regret having two dishwashers, a boiling water tap and oak stained cabinetry. If you drink tea, a boiling water tap should be the first thing on your list. It’s not just for your regular cuppa – it will be used throughout the day when cooking and cleaning. While it seems excessive, two dishwashers is a godsend to any busy family and really does mean dishes will never stack up in the sink.

Having everything on display

I wish my kitchen looked a little more like this one I designed for a client.  I love how all the mechanics of the kitchen (the fridge, freezer and dishwasher) are hidden away in under-counter drawers, while the floor-to-ceiling cupboards provide really substantial storage. It makes for such a fantastic entertaining space that accommodates lots of people in a relatively small room. The Soane Scrolling Fern wallpaper also really elevates the room and accentuates the ceiling height. Wallpaper in a kitchen isn’t necessarily practical for everyone but for a girl about town, it worked brilliantly.
