Single-Storey Extension Cost Calculator
What Affects The Cost Of A Single-Storey Home Extension?
There’s lots to consider when building a single-storey extension, including:
Size of Extension: The biggest cost of a house extension is the build cost (materials and labour). The larger the extension, the larger the cost.
Insurance: This will likely increase your premium but it’ll be necessary to let your home insurance company know of upcoming works to ensure you’re covered during the development work and that your new extension is included in the policy once complete.
Planning Permission: Not all extensions need planning permission as they fall under permitted development rights. For more information on what’s required view the official Government site.
Architects: Our team of architects will work with you to come up with the perfect design that suits your requirements, secure accurate quotes and aid with the planning permission process.
Clearing the space & Groundworks: There’s often a lot that needs doing before any work can begin, such as removing trees and shrubbery, dismantling awnings and patios and moving drains. Depending on the extent of work here, the cost can increase.
Windows & Doors: During the design process, we’ll discuss what windows and doors you’d like and if you’d want a roof lantern.
Finishing & Fittings: Once you have your home extension is built, you’ll need to decorate it. From kitchen accessories to bespoke finishing, the costing will be as unique as your home extension.
