About Primrose

Our organisation is built on the principles of first-rate service and professionalism; Primrose has always sought to exceed expectations and shatter preconceptions.

By acting as a main contractor and project manager we embrace responsibility and take ownership to deliver, helping clients to actually enjoy the often daunting prospect of undertaking a building project.

We encourage constant open communication to achieve mutual understanding and trust; an approach, which we feel, is the reason almost all our business is gained through recommendations.

Our teams centre around an experienced core of long-serving site managers whose combined experience provide the knowledge and leadership to make even the most challenging project run smoothly. We treat our people well and, as a result, have a very low employee turnover with many of our people having served for over ten years.

Our bespoke garden rooms service combines our wealth of experience delivering high-end construction projects, with the local personal service that comes from having a retained team of long-serving local craftspeople. Unlike some national garden room builders, we do not subcontract and we do not keep you waiting for months.

For more complex projects, we collaborate with many London based architects and regularly receive invitations for retrofit basements and whole-house refurbishments in London.
