At Urban Spaces, we specialize in creating high-quality, sustainable, and beautifully designed modular garden rooms and annexes. Our mission is to provide affordable, low-carbon, and thermally efficient spaces that enhance your lifestyle while minimizing environmental impact. Whether you need a dedicated home office, a stylish garden retreat, or a fully functional annex for additional living space, our modular solutions offer unparalleled flexibility and efficiency.

With nearly 30 years of experience in the home extension and renovation industry, we understand that expanding your living space can be a daunting process. Traditional construction often involves long timelines, excessive costs, and disruptive building work. That’s why we have perfected a streamlined, modular building process that allows us to deliver and install fully customised, high-performance garden rooms and annexes within weeks.
