About Alexander Gemini

A hand holding pre construction service for homeowners and developers
to enable their construction project runs smoothly

Who we are

Alexander Gemini was created by Director Tyrone Alexander Koursaris BSc Hons, having studied at University of Reading and Graduating in Building Surveying and Construction Management, the view was to create a hand holding pre construction service for homeowners and developers to enable their construction project runs smoothly.

From the initial concept a one to one service has always been applied with a quality of service being paramount rather than a quantity of projects. To date the majority of clients are through recommendation and word of mouth. As the company has grown from strength to strength we have now embarked on a full turn key service being a complete Design and Build, meaning we not only deliver the pre-construction but the full on site construction with in house contractors.

How we work with you

Initially a meeting is held to introduce myself as well as explain the service that can be provided to the clients as well as to be introduced to the project and task in hand.

A full understanding of what is required to then be able to provide an accurate quotation.

The stages of how we work are as follows:

Rear extension under permitted development
  • 1 Initial meeting
  • 2 Full measurements & photographic survey
  • 3 Create the existing drawings and the first design
  • 4 Amendments to clients request
  • 5 Submission for the relevant permissions
  • 6 Full Building Regulation Drawings & Structural Calculations
  • 7 For Construction Projects we would then submit our competitive tender for the build itself
