Why not simply fill the gap. A simply straight board like the kickboard at the base or bottom point where the cabinets meet the floor can be inserted. This can even be enhanced by using a cornice type finish and if you wish add a bit of colour to complement your kitchen . You would also choose to change colour of kickboard/plinth at the floor to keep a nice overall appearance. CJL

Hi. I'm putting an flush mounted extractor in ceiling above job in island. Want to create a shadow gap in bulkhead and have rope led like in picture In link https://www.houzz.ie/photos/harvey-jones-portfolio-phvw-vp~20476062 Wondering how much should I drop down and step out for bulkhead. Size of bulkhead is 2.4 x 1.2m

Hi Ed I was struck by the similarity with our new kitchen layout. We recently renovated and I absolutely did not want either an overhead extractor (because I wanted to raise the ceiling), but also did not want to cut expensive quartz for a pop-up extractor which all seem to give trouble eventually and basically don't work! The solution was a German-made Bora induction hob with the downdraft in the middle of the hob. I have to say that it was the best investment we made! Ours could not be ducted outside (which is always the best option) without losing too much efficiency so we went for a filtration system. It works even better than I thought removing all smells and grease! It was really well worth the money. ...and no ugly hood blocking the view out! Watch the videos on the website - it actually does work exactly like that! They also do different options where you have gas on one side and induction hob on the other with the extractor in a panel between the two. Definitely an investment! You really do need extraction though as Fiona said. Strong cooking smells will will be absorbed into your furniture and soft furnishings in an open plan area. The best of luck with your project. I hope you love the end result as much as we love ours.

Hi, I'm building an extension and the hob is going in the island. The ceiling is vaulted and there will be a large rooflight above the island. I was going to go with a downdraft extractor like Bora or Elicia style. However I'm afraid of grease build up on the rooflight. Has anyone any experience with rooflights directly above the hob in the island? If so, does the downdraft do enough to stop grease build up? Any other design solutions that could work? Thanks for your help, Steve
