Square One Projects, Square One Electrics, and Square One Decorating are three standalone companies working in partnership to deliver a complete home improvement solution. Each division specialises in its own trade, ensuring expert workmanship across construction, electrical, and decorating services.
Operating throughout Hampshire, we combine reliable teams, consistent communication, and a high standard of finish to give homeowners a smooth, well-managed experience from start to completion.

From large home extensions, renovations and carpentry, to fully certified electrical work, solar PV & battery installations, and high-quality decorating and finishing, Square One Group offers everything you need under one roof.

Our Story

Starting out as a small local team in Hampshire, Square One grew steadily through repeat customers and word-of-mouth recommendations. As our clients’ needs expanded, so did our services,  adding electrical and decorating professionals to ensure every stage of a project could be handled in-house.

Today, we manage everything from extensions and structural work to solar installations, rewiring, refurbs, decorating and final finishing. Although the company has grown, our focus remains the same: reliability, quality and genuine care for our customers.
