Factors That Affect the Cost of a Home Extension
Several key factors influence the total cost of your extension:
1. Size & Layout
Larger extensions cost more due to increased materials and labor.
A double-storey extension offers more space but requires additional structural work.
2. Type of Extension
Rear & side extensions are common and often more affordable than wraparound or double-storey extensions.
Loft & garage conversions can be cost-effective ways to add space without major structural changes.
3. Materials & Finishes
High-end finishes (e.g., bespoke kitchens, bi-fold doors, skylights) will increase the overall cost.
Using cost-effective materials can help manage your budget while maintaining quality.
4. Planning Permission & Building Regulations
Some extensions fall under Permitted Development, while others require planning permission.
Building regulations must be met to ensure safety and compliance.
5. Ground Conditions & Structural Work
Poor soil conditions, drainage issues, or removing load-bearing walls can add costs.
