Our Services in Detail
Loft Conversions & Extensions: Transforming an unused attic or adding a new extension can dramatically increase the value and livability of your home. We specialize in designing the structural framework for everything from simple rooflight conversions to complex dormer and mansard conversions, as well as single- and double-storey extensions.
Subsidence Investigations: Cracks in walls or uneven floors can be worrying signs. Our experts conduct thorough subsidence and movement investigations to diagnose the cause and recommend the most effective and least invasive remedial actions.
Basements & Internal Alterations: Creating a new basement requires careful planning and expert engineering to manage excavation, waterproofing, and structural integrity. Similarly, removing internal walls to create open-plan living spaces requires precise calculations to ensure the remaining structure is properly supported. We handle it all, providing the necessary drawings and calculations for building control approval.
New Build Design: We offer comprehensive structural design for new residential properties, working alongside your architect to create a safe, stable, and efficient structure from the ground up.
Whether your project is in its infancy or you need expert advice on an ongoing build, we are ready to assist. Contact us today to discuss your requirements and discover how our expertise can bring your project to life.
