Frequently Asked Questions

How much does a loft conversion cost?

The investment required for a loft conversion varies significantly and depends on several key factors. The size of the loft, its location, the specific type of conversion you choose, and any additional building work required all play crucial roles in determining the final price. Be assured, that at iBuild we give you a detailed and accurate price from the start, so there are no surprises later on.

For straightforward projects, costs typically start at around £25,000. These might include basic Velux conversions which are less intrusive and require fewer structural changes. On the other hand, more elaborate conversions such as Dormer or hip-to-gable, especially in larger homes or those in high-cost living areas, can see prices climbing to £100,000 or more. These figures account for both the complexity of the job and the high-quality materials and craftsmanship involved. Typically, the budget invested into your new loft is added to the value of your home.

At iBuild, we understand that upgrading your home is a major investment, and we believe in making this process as transparent and flexible as possible. That’s why we offer personalised consultation to align with your budget and expectations. We’ll help you navigate the options and provide clear, detailed estimates so you can make an informed decision. Additionally, we can tailor a payment plan that suits your financial needs, ensuring that your loft conversion is both affordable and transforms your available space.

Do I need planning permission for a loft conversion?

Generally, loft conversions fall under the category of permitted development, which means they do not usually require planning permission. This classification allows you to enhance your living space without the lengthy processes associated with formal planning approvals. However, it’s important to note that this applies as long as the modifications adhere to specific limits and conditions set forth by local building regulations. At iBuild we have a huge amount of experience in working with local building ‘regs’ on loft conversions throughout South Wales and especially working with Cardiff Council.

At iBuild, we’re committed to making your renovation journey as smooth and stress-free as possible. We’ll guide you through all the necessary documentation and procedures. Our team has extensive experience in managing these processes efficiently, ensuring that your loft conversion meets all legal requirements without any hassle on your part. We’ll handle everything from initial design assessments to the final sign-offs, so you can focus on planning your new space.

We will be there to help you with any paperwork you need for your loft conversion.

Do loft conversions add value to a home?

Loft conversions are an excellent investment, offering a significant return by increasing the value of your home, especially if you’re considering selling in the future. According to a 2020 report by Nationwide, adding a double bedroom and a bathroom through a loft conversion can potentially boost your property’s market value by up to 20%. The actual increase can vary depending on factors like the property’s location, the quality of the conversion, and current market conditions.

Beyond just adding monetary value, a loft conversion can transform unused attic space into vibrant and functional living areas. Whether it’s an extra bedroom, a home office, or a private retreat, each addition is tailored to enhance your living experience while maximising your property’s footprint.

At iBuild, we understand that every home is unique. That’s why we offer customised loft conversion solutions that not only meet your specific needs but also complement the existing structure and style of your home. Our expert team ensures that every conversion is meticulously planned and executed to enhance both the aesthetics and functionality of your property.

Investing in a loft conversion not only makes financial sense but also improves the quality of life within the home. Let us help you unlock the full potential of your property with a bespoke loft conversion that promises both immediate enjoyment and long-term value.

How long does a loft conversion take?

Every loft conversion is unique, and as such, the duration of the project can vary significantly. Simpler conversions, such as adding a few skylights or adapting existing space, typically require about 4 to 5 weeks to complete. More complex projects, like creating extensive Dormer or hip-to-gable conversions that alter the structure of your home, can take up to 12 weeks.

At iBuild, we understand that any home renovation can disrupt your daily routine. That’s why we are committed to making your loft conversion experience as smooth and stress-free as possible. From the initial consultation to the final touches, our team will be there to guide you through every step of the process. We pride ourselves on our meticulous planning and communication, ensuring that you are kept informed and involved at every stage.

Our goal is to minimise the impact on your household while delivering a high-quality loft conversion tailored to your needs and preferences.
