Professional Building Services in Conservatory Conversions

For over 22 years, Foundation and Finishing has been delivering exceptional Conservatory Conversions services across Greater London. Whether you're adding space with a side return, creating an open-plan kitchen-diner, or building a double-storey addition, we handle every detail from planning permission to final completion.

Many older conservatories suffer from poor insulation, uncomfortable temperatures, and dated designs. Rather than starting from scratch, a conservatory conversion upgrades the structure so it behaves more like a proper extension. This may involve replacing the roof with a solid or hybrid system, improving glazing, upgrading the base, and adding proper heating and insulation. The aim is to create a room you can genuinely use 365 days a year.

We assess the existing structure, foundations, and frames to determine what can be retained and what should be replaced. Our team then designs a conversion that suits your home, often introducing new rooflights, internal ceilings, and improved lighting. We handle all building control aspects and ensure the new space ties smoothly into adjacent rooms, both visually and thermally. The result is a comfortable, practical room that feels like a natural part of the house instead of an awkward add-on.
