Double Storey Extensions Explained!

Many growing families who are looking to extend their homes, usually consider a single-story addition to their home. They often choose this option because they simply want to add an extra room or increase the living room space.

Rather than a single-storey extension, we recommend a double storey-extension. This is because it allows you to accommodate your growing family both upstairs and downstairs, making it a lot easier for you in the long run.

What exactly is a double-story extension, and why would you want one for your home?

What is a Double-Storey Extension?

When you increase your home's ground floor and first floor, it's known as a double-storey extension. So you're not only expanding your ground floor living space, but you're also expanding the space upstairs. This allows you to increase the space in the living rooms, dining rooms to add additional bedrooms or even a bathroom. 

When compared to a single-story extension, these projects are considerably larger, yet they can still be finished on time and within budget. Here at Substructure Developments Ltd, we offer a range of extension services throughout Maidenhead, Windsor and Ascot. Head over to our gallery page and look through our previous projects!

Do I need planning permission?

One of the most crucial questions you'll want to ask yourself is whether you'll need planning permission, especially when you are considering getting a double-storey extension added to your home. Here at Substructure Developments Ltd, we highly recommend that you submit an application to your local council and gain approval before going ahead with a big extension project, only so that it will give you peace of mind knowing that you have followed all the necessary steps needed.

Our professional builders also suggest consulting with an expert builder to determine what kind of permission you'll need for any extension services you might need. Our team is here to answer any queries you may have; please contact us using the information provided below.

Types of the Double-Storey Extensions

Extension at the Rear: Rear extensions are usually built in the garden, at the back of the house. It is a perfect option for semi-detached and terraced houses. However, ample garden space is required for such extensions. 

Extension at the Side: Luckily, the side double-storey extension does not require the garden area, but only the confined space at the side of the house. It is an ideal option for semi-detached and detached houses. However, neighbouring houses with overlooking windows are a notable limitation to side extensions. 

Wrap Around Double Storey Extension: These include a blend of rear and side extensions and are a significant addition to the existing home size. This type of double-storey extension is suitable for semi-detached and detached houses. 

Extension at the Front: Front extensions are a rare type of two-storey extension since they require expanding the house's front area. This can alter your home's entire appearance and is feasible mainly for detached houses with a big space at the front. 

Average Cost of Double-Storey Extensions 

A double-storey extension's average per square metre cost is £1,000-£1,750. The average time required to build a double-storey extension is 8 to 14 weeks. 

Several factors can affect the cost of a double-storey extension, including your location, size in square metres, type/structure of the roof, and finishes such as roof lights, flooring and windows. 

Additionally, you can expect to pay necessary fees such as construction, planning, designing, and building regulation. 

So, while planning a home extension project, ensure you set a clear budget that covers all of these costs.
