How To Divide A Large Room With An Interior Wall

You often hear people complaining about a lack of space in their home but it’s rare to hear somebody complaining that they’ve got rooms that are too big. However, a large room can actually be a bit of a burden because you’ve got a lot of wasted space in there. But you can make more efficient use of that space if you divide the large room into 2 smaller ones. You could create an en suite bathroom or even a home office in the spare room. A lot of people think that putting up an interior wall is a massive job and they’ll have to call in a professional but that isn’t always the case. If you’re not very handy, it might be best to leave it to the experts but if you know your way around a toolbox, you should be able to do it yourself. However, it’s still a big job so you need to proceed with caution. Here are some basic tips to help you avoid any big mistakes.

Check Planning Permission

When you’re making big changes to the house, you might need planning permission. Even though it’s an interior wall, you might still need permission. If you decide to skip this step and go ahead with building the wall anyway, you might end up having to rip it down later on if you get found out, and you’re going to be the one paying for it. Most of the time, you shouldn’t need permission but it’s worth checking anyway just in case.

Organise Fixtures

When you’re deciding where to put your new wall, you’re going to have to think about the fixtures in the room. You need lighting, plug sockets, and maybe plumbing depending on what the second room is going to be. Have an electrician and a plumber come in and have a look so they can tell you what the options are. You don’t want to put a wall up only to find that it’s going to be a big hassle to put sockets in the new room.

Use Good Quality Materials And Tools

The job is only as good as the materials that you use so make sure that you don’t cut costs. When you’re buying plasterboard, timber and dry lining tools always shop for quality, not price. You’re already saving money by doing the work for yourself so you can afford to invest a bit more money in good quality tools.


People often underestimate the importance of proper insulation in an interior wall because the exterior walls are already insulated. However, it is still vital that you insulate the interior wall properly, otherwise, your new home office is going to be freezing cold in the winter. You may also need sound insulation so you can concentrate properly. You can get some great slab insulation that’s easy to install so you should have no problem doing it for yourself.


Once you’ve put your wall up, it’s time to paint it. It would be a real shame if you cut corners here and don’t paint it properly after all of your hard work. Make sure that you take your time to prepare the walls properly for painting and buy good quality paint.

If you’ve got a large space that you’re not really using, you should consider splitting it in two with a partition wall.
