Exceptional Renovations and Bespoke New Builds

At AB Conduit, we undertake the renovation and reconfiguration of significant private homes, as well as the construction of new residences of the highest architectural and material standard.

Our renovation work respects the character and provenance of each property, whether it is a listed manor house, a regency townhouse, or a historic rural estate. We collaborate with architects and conservation specialists to deliver thoughtful alterations that introduce contemporary performance and comfort while preserving original intent and detail.

For new homes, we construct architect-designed residences with elegance, longevity, and technical precision. From country houses to contemporary retreats, each project is managed with discretion and built with exceptional craftsmanship, using materials and methods appropriate to the setting and scale.

Whether restoring a legacy property or commissioning a new one, we bring clarity, care, and excellence to every stage of the process.
