foundations type needed for extension come conservatory to an existing single storey extension

Short answer is yes ! foundations depth for domestic extensions is not as a rule dictated by the amount of structure going above but the type of soil that is below. Ie a two storey extension has the same depth foundations as a fully glazed conservatory down to floor level. Its not the weight that is the problem it is the movement of the ground under the foundation. Regards Frank Base Construction Ltd

Weight Distribution: While the front of your conservatory may consist primarily of glass, it's essential to consider the weight distribution of the structure as a whole. Even though glass is relatively lightweight compared to solid walls, the overall weight of the roof, glass panels, and any supporting framework must be taken into account. Structural Integrity: The footings play a crucial role in providing stability and supporting the weight of the conservatory. They must be designed to withstand any potential lateral or vertical loads, including wind forces and the weight of the structure itself. Building Regulations: Local building regulations may stipulate specific requirements for conservatory footings, including minimum depths, sizes, and reinforcement. It's essential to consult with your local building control authority to ensure compliance with these regulations. Professional Advice: Consulting with a structural engineer or building control officer can provide valuable guidance on the design and construction of conservatory footings. They can assess the specific requirements for your project based on factors such as size, design, and site conditions. Existing Structure: Consider the impact of the existing single-storey extension and the dropped conservatory on the ground conditions and load-bearing capacity. Any changes to the existing structure may affect the requirements for the new footings.
