This Listed building and former Courthouse had been converted to a small house and extended at lower ground level to the rear with a timber and glazed addition incorporating living accommodation. We were appointed to look at converting an existing loft space adding additional bedroom accommodation, but a pre-application process revealed this would not be supported. Therefore, alternative options were presented and a side extension proved to be the preferred option. The new addition aims to be diminutive with accommodation tucked into an under-croft level, appearing single-storey from the street. The architecture is also modern in style and broken away from the existing, but utilizing similar materials for visual continuity.
