Services
Barn Conversions
We transform agricultural buildings into residential spaces using Class Q permitted development rights. Our process includes feasibility studies, planning approval, and bespoke design with exposed beams and energy-efficient features. We retain heritage elements while integrating modern comforts like smart home technology, ensuring compliance with size and location constraints for sustainable rural living.
Stone Work
Specialising in natural stone construction, we create durable extensions and new builds that harmonise with rural landscapes. We source reclaimed or local quarry materials, offering thermal mass benefits and low-maintenance finishes. Our expertise includes traditional stonework techniques that ensure timeless aesthetics while incorporating modern insulation standards for energy-efficient properties across Buckinghamshire and Bedfordshire.
Self-Build Homes
We deliver turn-key self-build homes from concept to completion, managing planning, construction, and smart technology integration. Our team provides design support, sustainable material selection, and project management for individual homes or estates. We combine heritage building methods with contemporary innovations to create energy-efficient residences tailored to client specifications in Milton Keynes and surrounding counties.
Conservation Projects
Our conservation specialists restore listed buildings and properties in protected areas using traditional craftsmanship. We preserve original features like stonework while meeting modern standards through sympathetic renovations. Services include structural repairs, material sourcing, and compliance with conservation regulations, ensuring historical integrity remains intact during upgrades to period properties across Northamptonshire and Bedfordshire.
Extensions
We design and build bespoke extensions that add living space and property value. Services include two-storey or traditional designs with full project management from planning to finish. Our client-focused approach allows staged decision-making, with options for partial or complete project oversight, ensuring extensions meet both practical needs and aesthetic preferences in Milton Keynes and surrounding areas.
