Extending the ground floor of your home is one of the most popular and affordable ways to add practical living space to a property. It’s also a great way to get creative with your home – to add character alongside functionality to make it truly yours. Here are some elegant and attractive modern single-storey extensions and extension design ideas to inspire your project!

Types of Single Storey Extensions

Depending on the design of your house and planning permissions, you can typically use one or more of these methods to extend your home.

  • Rear Extensions

Rear extensions are ideal for terrace houses and homes where there is no practical way to extend upwards or out to the side. This extension makes use of your garden to incorporate new, usable space into your home. The great thing about these extensions is that you don’t need planning permission if the extension doesn’t extend more than 4m beyond the original rear wall of the house if it is a detached home, and no more than 3m if it is any other type of home. 3m may not sound like much, but it adds a huge amount of usable space in reality – especially if you add on patio space in the garden at the same time.

  • Side Extensions

The side return is one of the least-used portions of the property, so it makes sense to extend your home out to the side and gain some much-needed width to your ground floor living space.  A side extension is a great option if you don’t want to sacrifice any garden space. You don’t need planning permission for a side extension as long as it is 4m or less in height (3m if eaves are within 2 metres of a boundary), single storey, and must not be wider than half the width of the original house.

  • Wraparound Extension

A wraparound extension combines a side and rear extension to create a large, L-shape extension that wraps around the existing ground level. It’s the largest type of extension and therefore makes the biggest difference to your living space. As a result, it’s a great option if you want to completely reinvent your floor plan, adding a ground floor WC or utility room, or large, shared family space.
