Transform Your Home with a Loft Conversion
Looking to add space, value, and functionality to your home? A well-designed loft conversion is one of the most effective ways to increase your home’s value, often up to 20%. But beyond financial gain, it allows homeowners to unlock extra space without extending outward. With property prices rising, converting your loft is a smart, future-proof investment.
At Ecoden Constructions, we specialise in loft conversions in London, delivering beautifully crafted spaces that transform underused lofts into modern living areas. Whether you’re expanding your family, setting up a home office, or seeking an extra bedroom, our loft conversion services provide a seamless way to enhance your property without the cost or hassle of moving.
Our Loft Conversion Process
Our streamlined and professional approach ensures a smooth and successful loft conversion from start to finish. Here’s how we work:

Step 1: Free Consultation & Site Survey
Every project starts with a free consultation, where our team evaluates your loft space, discusses your goals, and offers expert advice. We provide a no-obligation, tailored quote based on your specific needs.
Step 2: Design & Planning
Our architects and designers work closely with you to craft a personalised layout that enhances both function and aesthetics. Using cutting-edge tools, we bring your ideas to life while ensuring compliance with local building regulations.

Step 3: Approvals & Permissions
Navigating planning permissions and building regulations can be complex, but our team has it covered. Whether it’s a party wall agreement or a full planning application, our loft conversion contractors handle all necessary paperwork.

Step 4: Construction & Installation
Once approvals are secured, our experienced loft conversion builders get to work. We follow a detailed project timeline and use high-quality materials to ensure structural integrity, safety, and lasting results.

Step 5: Final Touches & Handover
From flooring and lighting to final finishes, we perfect every detail. Your loft room conversion is then professionally cleaned, inspected, and handed over, ready for you to enjoy.
Step 6: Aftercare & Ongoing Support
Our commitment doesn’t end at project completion. We provide full post-conversion support to ensure your new space continues to meet your expectations.

Our Loft Conversion Services
At Ecoden Constructions, we provide comprehensive loft conversion services in London that cater to a wide range of property styles and customer needs. Our services include:

Dormer Loft Conversions
A dormer loft conversion is one of the most sought-after styles across London, offering increased headroom, natural light, and substantial floor space. This type of loft room conversion is perfect for creating spacious bedrooms, ensuite bathrooms, or functional home offices. It’s ideal for both mid-terrace and semi-detached homes and often falls under permitted development.

Velux Loft Conversions
If your home already has ample roof height, a Velux loft conversion is a smart, cost-effective solution. By installing high-quality Velux roof windows, we enhance natural light and ventilation, transforming your attic into a bright, livable space. Our loft conversion specialists ensure that the existing roofline remains untouched, making this one of the least disruptive conversion options.

Hip-to-Gable Loft Conversions
A hip-to-gable loft conversion is a popular choice for semi-detached and end-of-terrace properties. This method extends from the side of the roof (the “hip”) into a vertical wall (the “gable”), dramatically increasing internal loft space. This allows our loft conversion contractors to create full-sized rooms that blend seamlessly with the structure of your home

Mansard Loft Conversions
Mansard conversions are especially popular in central London areas where planning regulations require a more subtle aesthetic. By altering the roof structure at the rear of the property, this conversion offers maximum usable space and flexible design options. Though it typically requires planning permission, our team handles the entire process, making it simple and stress-free for you.

Custom Loft Room Conversions
Looking for a truly unique loft space? Our custom loft room conversions are tailored to your exact needs whether it’s a luxurious guest suite, nursery, art studio, or entertainment room. As an experienced loft conversion company, we collaborate with you at every step to create a space that fits your lifestyle and maximises the potential of your home.
