Turn an underused outdoor space into a bright, modern room with an Eco Extend flat roof extension. Whether you’re opening up the back of your home, adding a new kitchen-diner or creating a snug, office or playroom, a flat roof keeps the external look clean and contemporary while maximising internal headroom. Based in Liverpool, we take care of everything from early design ideas and structural considerations through to planning, building control and final finishes, so your new space feels like a natural extension of your home.
All of our extensions are built using Dragonboard as part of the structure, giving you a strong, fire-resistant and moisture-resistant envelope that’s ideal for the UK climate. Combined with modern warm-roof build-ups, high-performance insulation and quality coverings, your flat roof extension is designed to be energy-efficient, low maintenance and long-lasting. While many of our projects are in Liverpool and across Merseyside, we also deliver flat roof extensions throughout the North West and on selected projects nationwide.

A flat roof extension offers a cost-effective, flexible way to add space without overwhelming your garden or changing the character of your home. It’s perfect if you want wide sliding or bi-fold doors, roof lanterns or large skylights that flood the new room with natural light. Flat roofs can also make it easier to hide gutters and services, create clean internal ceilings and future-proof the space for potential upgrades such as solar panels. We’ll talk you through layout, glazing, insulation and lighting so the extension works beautifully day to day.
From tight terraced plots in Liverpool to larger gardens across Merseyside, Cheshire, Lancashire and the wider North West, we design each flat roof extension around the property, the plot and local planning guidance. Our team understands how to manage falls, drainage and upstands correctly, so water runs off efficiently and details stay watertight. Wherever you are, you get honest advice, tidy workmanship and a carefully managed build that respects your home and your neighbours.
Modern flat roofs, when designed and installed properly, are very reliable. We use quality membranes, correct falls, proper drainage and robust edge details, combined with a Dragonboard structure, to create a durable, watertight roof that’s built to last.
Costs depend on the size, design, specification and how much structural work is required. After a site visit to your home in Liverpool or the surrounding areas, we’ll provide a clear, fixed quotation so you know exactly what’s included.
Some flat roof extensions fall under Permitted Development, but this depends on height, depth, location and any previous alterations. We’ll advise you on the best approach for your property and handle planning and building control applications if they’re required.
Timescales vary with the size and complexity of the project, as well as access and weather, but most flat roof extensions take several weeks from breaking ground to completion. We’ll agree a realistic programme before we start and keep you updated throughout.
Yes. Flat roofs work brilliantly with lanterns and skylights, bringing natural light deep into the room. We’ll design the openings, structure and insulation around your chosen glazing so you get a bright, comfortable space that performs well all year round.
