Adding an extension to your home can be a big decision, and one of the first things you’ll need to consider is whether you want a single story or two story extension. Both options have their pros and cons, and it’s important to weigh them carefully before making a decision.

One of the main advantages of a single story extension is that it can be easier and less expensive to build. Because it only requires one floor, there is less structural work involved and fewer materials needed. This can make it a more cost-effective option, especially if you’re working with a limited budget.

Single story extensions can also be easier to integrate into the existing layout of your home. Because they don’t require additional stairs or elevators, they can often blend in more seamlessly with the rest of the house. This can be particularly appealing if you’re looking to add a functional space, like a kitchen or living room, without disrupting the flow of your home.

On the other hand, a two story extension can offer some significant benefits. For one, it can provide more space for your family to spread out. With two floors, you can add extra bedrooms, bathrooms, or other living areas, which can be especially useful if you have a growing family or frequently host guests.

A two story extension can also be a good option if you’re looking to add value to your home. Because it adds more square footage, it can often increase the value of your property more than a single story extension. This can be especially appealing if you’re planning to sell your home in the future.

However, there are also some drawbacks to consider when it comes to two story extensions. For one, they can be more expensive to build. The additional floor and structural work required can add significantly to the cost, which may not be feasible for everyone.

Two story extensions can also be more disruptive to your daily routine during the construction process. Because there is more work involved, the construction process may take longer, which means you’ll have to deal with noise and disruption for a longer period of time.

Another thing to consider is the overall design of your home. If you have a single story home, adding a two story extension can change the look and feel of your property significantly. This can be a positive or negative depending on your personal preferences, but it’s something to think about before making a decision.

When it comes to getting planning permission for a home extension in the UK, the rules can vary depending on where you live. In general, single story extensions are more likely to be approved than two story extensions, especially if they’re in the back or side of your property. However, it’s always a good idea to check with your local council to see what the specific rules are in your area.

Another factor to consider when deciding between a single story and two story extension is the style of your home. If you have a traditional single story home, a two story extension may look out of place and disrupt the overall aesthetic of the property. On the other hand, if you have a multi-story home, a single story extension may not add enough space to meet your needs. 

Another thing to consider is the orientation of your home. If you have a south-facing property, a two story extension may be a good choice, as the additional floor can take advantage of the extra natural light and warmth. On the other hand, if you have a north-facing property, a single story extension may be a better option, as it can be more efficient to heat and light.

Another thing to think about is the overall cost of the extension. While a single story extension may be cheaper to build, it may not add as much value to your home as a two story extension. This is something to consider if you’re planning to sell your home in the future, as the return on investment may be higher with a two story extension.

One final thing to consider is the long-term needs of your family. If you have young children, a single story extension may be a good choice, as it can be easier for them to move around and play. On the other hand, if you have older children or frequently host guests, a two story extension may be a better option, as it can provide more privacy and space for everyone.

In summary, there are many factors to consider when deciding between a single story and two story extension. Think about your budget, the layout and style of your home, the orientation of your property, and your long-term plans for the property. And be sure to check with your local council to ensure that you have the proper permission for your chosen extension.
