I have known Monique Halloran for many years as our business relation started in designing our Town Garden in Oxfordshire. Monique’s perception of the landscape and her abilities of projecting herself  into a design which will bring you many years of joy and astonishments  are exceptional and a real asset.

From there Monique went into property development which requires  again a global approach of a property within its environment.  This new marketing approach of the property market  involves a long experience in Design and global management.  Our different collaborations since 2006 have all been very successful and exciting within secure financial projects.

Anne-Marie Joffrin

We are absolutely delighted with the landscape and garden design work that Monique created for our home. Although the house was only completed in 2006 the garden already has a mature and well established feel through the use of larger trees and the careful selection of planting and materials and this has really helped the house to work within its setting.
