Types of Extension

Why move, when you can create more space? Home extensions can be the answer to your home quandaries. But which type of extension will best suit your home, family and requirements? There are typically 5 main extension styles to choose from.

Extension with 4 Season Roof

Rear Extension

Just as the name implies, a rear extension is placed at the back of your home, extending your living space onto the rear garden or patio area. They’re mostly used to create a larger open plan kitchen/diner and blend the indoor/outdoor space.

You can expect to pay around £40,000 for a 5x5m extension and expect it to take 10-12 weeks to complete.

home extensions

Wrap Around Extension

Wraparound extensions tend to be a combination of a rear extension and a side return extension that combine to form an ‘L’ shape that wraps around from the side of your home to the back. A Wrap around extension is perfect for creating huge open plan spaces or equally giving you the ability to open up more layout possibilities.

You can expect to pay around £65,000 and will generally take 12-16 weeks to complete.

Home Remodelling & Extension

Side Return Extensions

Side return extensions utilise the alleyway or path down the side of your home. Many period properties use this space to house bins, bikes and other bits & bobs. Side return extensions run the length of the available space, allowing you to dramatically increase interior space without the need for planning permission in many instances.

You can expect to pay around £25,000-35,000 and will generally take 10-12 weeks to complete.

home extensions

Double Story Extensions

Double storey extensions can come in any one of the three previous extension types; rear, wrap and side return and then extend it over two floors as opposed to one. This greatly improves the amount of floor space created but savings can be made on the cost per square metre.

The majority of double storey extensions will need planning permission, so that’s something to consider during the planning your home extension project.

You can expect to pay around £80,000 and will generally take 20 weeks to complete.

Garden Room/Extension

Dormer Extension

Unused space in your attic is the perfect place to steal extra room from within your existing four walls.A dormer extension removes the roof’s pitch and creates a flat roof in line with the top of the already existing pitch. In turn this creates additional space in the shape of a box therefore creating real usable floor space and head height.

Loft conversions rarely need planning permission and are a more logical way to extend if you do not have the outside space for a typical extension.

You should estimate the cost to be around £45,000-55,000 for a 6 metre dormer and expect it to take 12-16 weeks to complete.

You can estimate a budget based on a square metre price of between £1,800 and £2,000. This is for your basic building materials including foundations, walls, roofing, plumbing, electrics and finishing.

Once you have a build cost estimate the main extras to the cost of the build are things like kitchens and bathrooms.

You can also expect to pay £5000 – £15,000 for a fitted bathroom.
