• House Extensions

Whether you have a growing family or simply want to increase your living space, house extensions can help you achieve your goals. House extensions can include everything from adding on an extra bedroom to increasing the size of your existing kitchen, living room or dining room. You could even add an in-law suite for visiting guests or extended family as well.

When considering the designs for house extension projects, some things to keep in mind are your existing floor plan and the amount of space you have available for building. If you have limited space to build in, you could consider a multi-level addition rather than one that is all one level. You could also consider adding a room that would serve multiple purposes in order to get the most out of this additional space. Some examples of multi-functional house extensions are libraries that double as home offices and sun porches.

Compare House Extension Costs

Average house extension costs will largely depend upon the size of the addition and whether or not the ground must be leveled before building. Adding special features such as skylights, fireplaces or deluxe cabinetry will increase the cost as well. A two-story addition will be more expensive than one that is only a single story; however, it is usually cheaper than adding two separate rooms would be. Local building codes that require an upgrade to plumbing or electrical work can also increase the cost of house extensions.

House Extension FAQs

Q. How much will a house extension cost?
A. The type of extension you plan on doing will have a significant effect on the total cost. For instance, a simple loft or conservatory extension may not cost as much as a full two story extension. The price will depend on the amount of labour required, materials used, and alterations such as removing an existing external wall (which could involve steel beams and flooring). Other cost factors include digging, excavation, altering foundations, guttering and more. The cheapest estimates usually average £15,000 (less at £4000 for a conservatory) although for an accurate estimate, it’s important to request a quote which can be done right from this page.

Q. Is there a limit as to how big house extensions can be?
A. In some cases, you could be limited by the boundaries of your property or existing utility lines. A two-story extension might be a better choice whenever there is a limited amount of space to build on. Local planning restrictions could also limit the size of your house extension.
