A home extension is a big decision that comes with huge expenses. So, if you are planning to go ahead with it, here are some things to consider!
Why Consider a Home Extension?
For many people, having a house extension can be a daunting experience since there goes a lot into planning one. But in most cases, a home extension is cheaper than buying and moving into a new home. Considering all the stamp duty and legal fees, it becomes more expensive than an extension.
Talking about the perks of home extension, it adds 10 to 20% of home value. Hence, if the entire packing and unpacking thing is a hassle for you, a home extension can be a good alternative!
If you are going ahead with a home extension, you can even get loans for the same. You can get different types of loans. A £25000 loan is great for covering smaller expenses of the house extension project. However, don’t go for the first loan that you find online. Compare multiple loan interest rates and choose the one that best fits your needs!
What Affects the House Extension Cost?
A lot of factors influence the cost of a house extension. Since per square meter matters for extension, other factors are also involved:
1. Design and Planning
Hiring an architect, structural engineer, and surveyor will require you to invest some money. After that, getting planning permission, party wall agreements, and building regs approval will require money and time.
2. Extension Size, Shape, and Height
If you have larger extension requirements with premium building materials, the cost will be on the higher side.
Even groundwork will affect the final cost. For example, improving the drainage, digging a foundation, or building on uneven land will cause a rise in the price.
4. Building Site Constraints
Depending on the site, additional costs can be added. There can be certain issues that can cause this, for example:
- Certain soil types will demand specific building material
- Changes to walls or steelwork
- Moving drainage, gas, or pipes
5. Right Trades people
This depends on your home extension work and how many trades people would be required. Plumbers, builders, electricians, painters – everyone has their skill sets with their pricing. Being a small or big contractor also affects the final cost.
