If you plan to entertain a lot in your new home, then an open-plan layout is probably a good option for you. A joint kitchen/living/dining space will offer you and your guests lots of circulation room, and means anyone cooking will not be taken away from the group. If your garden and budget allow it, consider sliding or bifold doors leading out to a patio, to make the most of warm summer evenings. Lovers of outside cooking might want to include an outdoor kitchen in this space.
If you are building a big open-plan living space, make sure to include a smaller snug somewhere nearby where noisy games consoles and objects like pool tables can live so as not to disturb anyone cooking or working at the table. You could even remove the television from the main open-plan living space altogether, to make it even more of a conversation-orientated area.
Open plan areas can feel big, sometimes too big, and furniture can get lost. Be sure to consider the layout of all your furniture within the space; bigger is not always better, and you don’t want to be left with a lot of empty corners. The more open space you have, the fewer walls there are on which to hang artwork or rest furniture, and it’s also harder to heat. Maybe add underfloor heating instead of using conventional radiators to disperse heat better and free up valuable wall space.
If you don’t tend to host dinner parties then perhaps separating the kitchen off is a better idea. Frequent card or board games nights might inspire a large open-plan living/dining room instead, with pendant lighting hanging low over the table and plenty of room for circulation.
Your plot might enjoy sweeping views of the surroundings. In this case, an open-plan layout will open up these vistas to all the main circulation rooms. Even better, an upside-down design will mean the views are not wasted on bedrooms that people will just be sleeping in. If your open-plan area is particularly large, consider a neutral colour scheme with pops of one or two standout colours spread throughout the different functional zones, to tie it all in together. Open plan may sound on-trend but, ultimately, it’s your decision.
