Superprime Restoration and Retrofitting

Super Prime Residential Builders in Dorset. Heritage & Architect-Led Excellence

We are AB Conduit Building, based in Sherborne, Dorset, and working throughout Dorset, Somerset, and Wiltshire. We specialise in transforming luxury homes, creating bespoke new builds, and delivering exceptional residential projects.

We work with private clients, architects, and interior designers to deliver exceptional homes, built with meticulous craftsmanship, discreet project management, and uncompromising attention to detail.

Exceptional Renovations



At 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.
Our team, alongside our trusted partners, crafts exceptional detailing for the most discerning residences. From bespoke marble installations and artisanal joinery to exquisite stonework, plastering, and seamlessly integrated smart-home systems, every element is executed with unparalleled precision, craftsmanship and delivered with confidentiality.
