Understand Your Motivation and Objectives

Why are you considering a house extension? Is it to create more living space, enhance the functionality of your home, or boost your property’s value? Identifying your specific reasons for embarking on your project is critical, as it will shape many aspects of your extension project. This clarity can further help define your budget, designs, and the choice of contractors to work with.

Your Living Space Needs

Maybe your family is expanding, or you simply need more room to breathe – a house extension can solve this. Come up with a list of what you would like to achieve with your new space, whether it’s a new bedroom, a larger kitchen, or a dedicated home office.

Boosting Property Value

Home extensions, if done right, can significantly increase the value of your property. If your primary aim is to boost your property’s resale value, research which types of additions typically yield the highest return on investment in your locality.

Enhancing Home Functionality

Perhaps you’re craving a sunroom for relaxation, a game room for the kids, or a spacious, spa-like master bathroom. Clearly identifying these tailored needs will help ensure your new addition enhances your home’s overall functionality.

Set a Realistic Budget

Regardless of the scale of your project, setting a budget is a crucial step. Be realistic about what you can afford and prioritize your needs accordingly.

Cost per Square Foot

The cost of room additions usually depends on the square footage. According to HomeGuide, in 2021, the cost of home addition could range anywhere from $80 to $200 per square foot, depending on the complexity of the project and your geographic location.

Design and Finishes

Consider the cost of the design and finishes you choose. If you’re planning a high-end kitchen renovation with top-of-the-range appliances and finishes, budget for a higher cost per square foot.

Contingency Plan

Unforeseen issues often come up during construction. Whether it’s previously undetected structural issues or unexpected changes you decide to make midway, these could inflate your budget. To mitigate this, include a contingency allowance of 10-20% above your estimated budget.

Hiring the Right Professionals

You need the right professionals to bring your dream to life. Check credentials, ask for references, and ensure they are well-versed in managing home extensions.


While selecting a builder, consider their experience, reputation, and previous projects. Ensure they are appropriately licensed, bonded and insured. Ask about their approach to handling unexpected obstacles that may arise.


If your home extension requires significant structural changes, it might be wise to hire an architect. While many builders offer design services, an architect will help you plan your space effectively and ensure it aligns aesthetically with the rest of your home.

Project Manager

Hiring a project manager lets you delegate the stress of coordination and oversight while ensuring your project stays on budget and schedule.

Planning Permission and Regulations

Before beginning your project, familiarize yourself with any necessary permits and regulations in your locality. These can be as simple as adhering to set back rules or more stringent if you’re living in a historic district.

Designing Your Addition

Having a well-thought-out design helps ensure the new addition blends seamlessly with the rest of your home.

Consider the Flow

Think about how the addition will influence traffic flow in your home. It should not disrupt the existing layout but rather complement it.

Light and Ventilation

Ensure your design allows for ample natural light and proper ventilation. This not only promotes energy efficiency but also contributes to the overall livability of the space.

Exterior Design

Your new addition should complement your home’s existing exterior design. Whether it’s the roofline, siding, or windows, ensure continuity for a visually pleasing exterior.

By understanding your motivations, setting a clear budget, hiring the right professionals, adhering to necessary regulations, and well-executed design plans, you can mitigate potential hurdles and ensure a seamless execution of your home addition project.
