Hi there, just wondering if anyone can advise me on the best solution to my flooring problem. We have just had an extension done on the back of our house and knocked through 3 rooms to open it all up. The floor in the original kitchen is 10-15mm higher than the rest of the area and none of them are particularly level. My thinking was to dig up some of the higher floor and then self level the lot but this would be pretty expensive for materials as it's 32m2 in total. Is this my only option, we are putting laminate down so it has to be pretty flat. Below is a photo, the raised area is to the right of the picture, Thanks.
