Bespoke Garden Rooms for Haywards Heath Properties
ER3 Group LTD, registered company 16386146, brings professional construction expertise to your doorstep in Haywards Heath. Unlike flat-pack modular suppliers, we specialise in delivering high-specification, bespoke garden rooms built to last. Whether you need a dedicated garden office, a tranquil outdoor studio, or a versatile hobby space, our team manages the entire project from initial design through to final installation. We serve the Mid Sussex area with a focus on durability, superior insulation, and professional-grade finishings, ensuring your new space provides year-round comfort regardless of the season.
Why Choose Us?
Our Proven Construction Process for Garden Rooms
We take a systematic approach to every build, starting with a thorough site survey to assess your land. Proper groundworks are the foundation of any high-quality outdoor building. We perform precise site preparation and install robust, heavy-duty foundations to prevent shifting or damp issues common in lower-quality installations. Once the substructure is set, our team erects the structural frame, installs energy-efficient insulation, and applies high-quality, weather-resistant cladding. We complete the build with secure roofing, windows, and doors, delivering a truly turnkey service that saves you the stress of coordinating multiple contractors.

Who We Are
Navigating Planning Permission and Building Regulations
One of the most frequent questions we receive from homeowners in Haywards Heath concerns legal compliance. Many garden rooms fall under Permitted Development rights, meaning you may not require full planning permission, provided your structure meets specific size and height requirements. However, we also understand the nuances of local authority guidelines in Mid Sussex. We ensure every project complies with current UK Building Regulations, focusing on electrical safety, fire safety, and structural integrity. We guide you through the regulatory landscape, so you can enjoy your new space with complete peace of mind.

Do your garden rooms need a concrete base? Yes, we always recommend a solid, level foundation to ensure long-term stability and to prevent water ingress. Can I use my garden room all year round? Absolutely. We use advanced insulation materials in our walls, roofs, and floors to ensure the building remains warm in winter and cool in summer. How long does the build take? While timelines depend on the complexity of the design, our start-to-finish project management approach ensures we work as efficiently as possible without cutting corners.
