Expanding your home can feel like a daunting task, especially when space and budget are limited. However, small home extensions provide an excellent solution for adding functional space without the need for a full-scale renovation. In this article, we’ll explore smart, cost-effective, and stylish extension ideas that can enhance your living space.
Planning Your Home Extension
Assessing Space and Budget
Before jumping into an extension project, it’s crucial to evaluate your available space and budget. A detailed plan helps prevent overspending and ensures that your new space aligns with your needs.
Legal and Zoning Considerations
Understanding local building regulations is essential. Some extensions may require planning permission, while others fall under permitted development rights.
Hiring Professionals vs. DIY
