The cost of a new house extension can vary widely depending on various factors such as location, size, materials used, labour costs, and the complexity of the design.


JMB Design and Build, based in Hertfordshire, can provide a general overview of the factors contributing to the cost of a house extension.


Firstly, the size of the extension plays a significant role in determining the cost. Larger extensions will generally cost more due to the increased materials and labour required. Additionally, the type of room being added, such as a kitchen, bathroom, or living area, can also impact the cost as certain rooms may require specialised fixtures or fittings.

Secondly, the materials used to construct the extension will affect the overall cost. High-quality materials such as hardwood flooring, granite countertops, and custom cabinetry are typically more expensive than basic materials. Similarly, choosing exterior finishes, such as brick, stone, or siding, can also impact the cost.


Labour costs are another important consideration when estimating the cost of a house extension. Labour costs can vary depending on factors such as the project's location, the availability of skilled labour, and the complexity of the construction. In some cases, labour costs may comprise a significant portion of the project's total cost.


Typically, JMB Design and Build house extension projects cost around £100,000. We work with all our clients and thoroughly plan out all the costs, ensuring we stay within your budget.


Other factors that can influence the cost of a house extension include the need for permits and inspections, site preparation and excavation, utility connections, and any additional features such as heating, cooling, or plumbing systems.

In addition to the direct costs associated with the construction of the extension, there may also be indirect costs to consider such as architectural fees, engineering fees, and the cost of obtaining permits and approvals from local councils.

It is also important to budget for unexpected expenses or contingencies that may arise during the construction process. Unforeseen issues such as structural problems, water damage, or changes to building codes can all add to the project's cost.


Overall, the cost of a new house extension can vary widely depending on various factors, but it's important to carefully consider all of the potential costs and factors involved before beginning construction.
