Whether you’re dreaming of a larger kitchen, an extra bedroom, a sunlit home office, or a luxurious open-plan layout, our expert extension builders are here to bring your vision to life.
With a focus on quality craftsmanship, planning expertise, and sustainable construction, we deliver home extensions in London that stand the test of time.
Our House Extension Process
At Ecoden Constructions, our structured, step-by-step approach ensures your home extension is delivered on time, within budget, and built to the highest standards of craftsmanship. Here’s how we work:
Step 1: Initial Consultation & Site Survey
We begin every project with a free on-site consultation, where our house extension planners assess your property, understand your goals, and explore the most suitable extension options for your space and budget.
Step 2: Design & Planning
Our experienced in-house designers and house extension builders work closely with you to create detailed architectural plans that reflect your lifestyle and enhance your home. We tailor every design to fit your property type, whether modern or traditional.
Step 3: Approvals & Permissions
From permitted development to full planning permission, we handle all applications and correspondence with local authorities on your behalf. Our experience as trusted extension builders means we know how to navigate the approval process efficiently.
Step 4: Construction
Once approved, our skilled team of home extension builders begins construction. We use only high-quality materials and proven building techniques to ensure durability, style, and long-term performance.
Step 5: Completion & Handover
As we near project completion, our site managers conduct detailed inspections to ensure every aspect meets our standards and yours. We walk you through your new space, provide maintenance guidance, and complete final touches
Step 6: Aftercare & Ongoing Support
We offer continued support and warranties for peace of mind. Whether you have a question post-build or need additional work in the future, our team is here for you.

Our Home Extension Services
Every home is unique and so is every house extension project we complete. We offer a variety of options tailored to your layout, lifestyle, and future needs including:
Rear Extensions
Rear house extensions are one of the most popular ways to increase living space, perfect for creating open-plan kitchens, dining rooms, or family lounges. Our house extension contractors will help design and build a layout that connects your home to the garden with maximum natural light and flow.
Side Return Extensions
If you own a terraced or semi-detached home, a side return extension is a smart way to utilise unused alley space. Our home extension builders are experts at converting narrow side areas into bright, functional spaces that completely transform the ground floor.
Wrap-Around Extensions
A wrap-around house extension combines a rear and side extension to create a large, versatile living space. This is ideal for homeowners who want to completely reconfigure their ground floor layout. We ensure seamless design continuity so the extension looks and feels like it’s always been there.
Double-Storey Extensions
Need even more space? A double-storey home extension adds valuable square footage on both floors, which is ideal for growing families who need additional bedrooms, bathrooms, or workspaces. As specialist house extension builders, we manage everything from structural planning to interior finishing.
Kitchen & Living Room Extensions
Update your lifestyle with a purpose-built kitchen, lounge, or multi-functional open space. From skylights to bi-fold doors and underfloor heating, we incorporate high-end features to make your new room both beautiful and functional. Our home extension contractors help tailor every detail to your vision.
