We are DPR

With increasing urban densification, accurate daylight and sunlight assessments are vital for responsible, commercial land development that optimises asset value, while also creating places that stand the test of time and benefit society.

We analyse daylight, sunlight and overshadowing impact using advanced climate-based modelling, generating robust reports for planning applications. At the forefront of evolving policy and meeting the highest industry standards, our expertise in this field has been trusted for over 40 years.

Party wall & neighbourly matters can be a highly complex area but, with our experience, knowledge and technical expertise, we guarantee a simple process that puts our clients’ objectives at the forefront – whether acting on behalf of developers or adjoining owners. Our specialist team works proactively with clients to ensure risks are identified at each stage of a project and the necessary advice is provided in a clear and concise manner, vital for ensuring compliance. We support developers and adjoining property owners on all aspects of neighbourly matters, including party wall and neighbourly disputes.

Successful projects rely on having full, up-to-date records of existing site conditions. The more complex the scheme, the greater the need for an efficient response with accurate information.

Using the latest laser scanning and GPS technology, we can provide 2D topographical survey plans, sections and elevations, boundary surveys, and 3D survey data and imagery for rights of light, and daylight and sunlight monitoring, often reaching otherwise inaccessible areas. In doing so, we unlock opportunities.

Our boundary determination surveys encompass initial site inspections, precise measured surveys, analysis of legal and historical documents, boundary plotting using Land Registry and Ordnance Survey data, mediation of neighbour disputes, and expert witness litigation support. Our services aim to accurately define and register property boundaries to resolve conflicts and ensure complete compliance.
