2025 Medium Renovation Project national winner: SG Design and Build (Construction) Ltd

National winner: SG Design and Build (Construction) Ltd

SG Design and Build (Construction) Ltd delivered a bold and brilliantly executed transformation of a Derbyshire bungalow, turning a tired layout into a light-filled, future-ready home. The aim was to redesign the layout, creating a spacious master bedroom suite, vaulted kitchen/living space, utility and snug, with expansive glazing that made the most of its views across the Derbyshire Hills. 

Working as both designer and builder, the SG team delivered a highly technical rear extension, featuring a vaulted structure and a striking full-height apex window. Their attention to detail was second to none, from the six-month-in-advance crane lift of a 700kg apex frame to the clever use of sun tubes and zoned underfloor heating. 

Precision and collaboration were central to the build. SG maintained clear communication across a large team of trades, designers and suppliers – many of whom are trusted, long-term collaborators. Managing tight deadlines, complex structural challenges, and a tricky site layout, the company kept the project moving with confidence, integrity and exceptional project management. 

Their clients praised the team’s friendly, transparent approach and said they were ‘delighted with our new and revamped spaces’. There wasn’t a single snagging issue at handover – testament to the quality of the work. 

As one judge commented, ‘SG have delivered professionally and very successfully… the completed project looks excellent and is a credit to all involved.’ This is a shining example of a young company bringing modern thinking, teamwork and real craft to a renovation that’s both technically ambitious and beautifully resolved.
