About Us

With over 40 years combined experience within the construction and development space, the business has taken on several facets and has sustained continuous growth over the last 10 years.

AJ Developments was formed in December 2010 by Mark Adams and Sebastian Janes.

After leaving Bryanston School in 2006 Mark Relocated to Bristol where he attended University, and gained a Degree in Business and Finance, before returning to the South Coast. Marks entrepreneurial tendencies, negotiation ability and commercial mind enabled him to see a large gap and business opportunity in the local market when starting AJ Developments. This has developed into a stronghold throughout Dorset and Hampshire and has been a catalyst for the expansion of the AJ Group. A keen Tennis player and Golfer, Mark will more often than not be found outdoors.

Coming from an experienced Construction background, Seb left Twynham School in 2007, and went straight into the Construction Industry to learn and develop his understanding and knowledge of the built environment and its processes. Having spent time on Site building his practical skills and expertise, Seb is a credible and informed individual, with a keen eye for identifying areas of improvement within our Industry. In his spare time, Seb is a family man and enjoys completing fitness challenges.

Fulfilling this void with affordable luxury housing solutions, AJ Developments have forged a stellar reputation for producing the highest quality Houses, combining meticulous detail and innovative spacial ideas with a professional and fun service.

Having recently made extremely positive waves in the Dorset and Hampshire area; setting ground breaking precedents AJ have, and continue to establish themselves, as a trusted, eminent business, who also provide career and contract opportunities for local and national trades.
