The Building Company

Based in West Kent we offer homeowners across the region the very best in house extensions, conservatories and internal alterations.

Established in 1993 we’ve brought the highest standards in general building services for over 16 years. Our team’s experience began in small construction projects with other companies until SPG was formed to offer a specialist conservatory installation service. Starting out providing just foundation bases we quickly expanded to offer a complete conservatories service specialising in bespoke designs to perfectly compliment gardens across Maidstone, Tunbridge Wells and Sevenoaks.

As a family company we focused on traditional family company values. High quality workmanship, fair pricing, caring and professional customer service quickly won us great word of mouth and before long over 98% of our work was coming from recommendations.

Expanding to offer house extensions we gradually built an experienced design team as well as bringing in expert support from fully qualified architects and surveyors. Developing a small, consistent and reliable team we have been installing everything from kitchens to demandingly sympathetic period and listed building renovations with the team almost unchanged in the last ten years.

Today we still aim to offer a comprehensive range of services to homeowners and occasionally the public sector such as schools. Our family values approach means all our customers get the advantage of our years of experience, recommendations and advice throughout every stage of a project with our team providing design, planning, drawings, building works, utilities connections and painting and decorating so all you need to do is make one phone call, and the job is done!
