SGB carries out commercial construction and maintenance work, including seismic strengthening, structural repairs, retaining walls, concrete works, government and education work, body corporate maintenance, facade remediation and commercial roofing. We love taking on complex projects that require detailed project management and seamless co-ordination of sub-trades.

At SGB, we’re passionate about residential renovations and extensions. Our team can design, project manage, and deliver new kitchens and bathrooms. We undertake exterior re‑cladding, retro‑fit double glazing, new window installations, re‑roofing, re‑lining, and full interior fit‑outs. Whatever the scale of your renovation, we can elevate both the function and feel of your home.

SGB can project manage any construction project from start to finish. We liaise with architects, land surveyors, engineers, the council, and interior designers to ensure every stage is well‑coordinated. Our team manages costs, subcontractors, and project timelines, providing a smooth and organised build from concept to completion.

SGB can accurately price any building project with our in‑house quantity surveyors. Whether you’re at the concept stage, preparing figures for the bank, or ready to begin construction, we provide clear and reliable costings. Throughout the project, we actively manage costs to keep your build on track and within budget.

SGB provides in‑house architectural design services, offering concept drawings and visualisations through to full building consent drawings and specifications. Our integrated approach ensures a seamless transition from design to construction, with clear documentation and efficient coordination at every stage.
