If you want to double the size of your house, create a modest extension, or need some structural repairs to your home, we are happy to assist you along the way.


Ellis Structures will work alongside you, helping you to increase the amount of space in your home, or reformat the existing floor plans to make better use of the space. We provide calculations and drawings to design the superstructure (above ground structural members), and substructure (below ground foundation design, etc.). With larger projects we recommend we work alongside your chosen architect as a key member of your team to achieve the design you are looking for.

We will work together with you, your architect and your builder to understand your requirements. We keep in close contact throughout the design stage and are at hand if needed during the build stage.  We use modern design systems, such as 3D modelling, to achieve the best solution for your project.  To limit the risks to your home, we recommend exposing areas of the building to fully understand the construction before you commit yourself to the project.  We also aim to help you understand the costs and possible alternatives.
