HDA prepared a landscape and visual appraisal to support a full planning application for the conversion of a cluster of traditional and modern barns on the Carrington Estate outside Flackwell Heath.  Permission has just been granted by Buckinghamshire Council (formerly Wycombe District Council) to create two dwelling houses, two B1 class offices and a flexible B1/B8 class business unit.  The permission, which includes a realigned site access together with associated parking provision and landscaping, was considered to be acceptable development in this Green Belt and Chilterns AONB location.


The site near Yearby, had become a victim of its own success, and having helped our client, obtain planning permission for the site back in 2014, we are now pleased that permission for additional car parking and widening of the existing vehicular access has just been granted by Redcar and Cleveland Borough Council.  The current metal entrance gates are proposed to be replaced by timber gates, which will be more in keeping with the site’s rural setting.


HDA has been overseeing hard and soft landscape works undertaken by Vascroft Contractors Ltd at Bhaktivedanta Manor, off Hilfield Lane, Aldenham, for the construction of a new Haveli (community halls) on behalf of the International Society for Krishna Consciousness. Vascroft has just been awarded practical completion on the building, though landscape snagging will continue into the next planting season. The main courtyard includes Indian Bean trees.


HDA is proud to have provided ecological input in support of Berkeley Homes’ successful planning application for the redevelopment of the former Horlicks factory in Slough.

This included an assessment of the effects of the 1300 home scheme on features of ecological interest, and the agreement of a package of mitigation and avoidance measures with Natural England and SBC to protect the ecology of the site and the off-site Burnham Beeches SAC.

During these challenging times, HDA is doing all it can to ensure safety of its employees, with all staff working and communicating efficiently from home.

We continue to provide all our usual landscape, ecology, arboricultural and heritage services, working in the best interests of our clients. Site survey work is currently possible in keeping with government requirements, whilst taking strict precautions. Get in touch if we can help with your projects.


HDA is delighted to announce that ownership of the practice has successfully transferred to an Employee Ownership Trust.

Whilst the company’s management structure remains largely unchanged, the Trust will own HDA on behalf of all employees, securing its future and giving employees a vested interest in the success of the practice.


Following recent approval of reserved matters for up to 200 dwellings at Hill Place near East Grinstead, HDA has now produced the landscape, ecology and arboriculture inputs into the construction tender package.

HDA is also working with the council to finalise the proposed Suitable Alternative Natural Greenspace (SANG). The SANG will be a significant new open space on the edge of East Grinstead, providing new public views of the re-opened Grade II listed Imberhorne Viaduct along the Bluebell heritage railway.
