Hayes Davidson

HD City Analytics Hayes Davidson has a team dedicated to visualisation for planning and regeneration, assessing the potential visual impact of new city development. We specialise in large, complex or contentious projects, collaborating closely with planning consultants and townscape advisors. We have developed rigorous methods to ensure precision and accuracy. 

This, combined with the skills to report against complex visual issues, has meant that the studio has built a highly successful track record of supporting major planning permissions. The team has 20 years' experience and has now worked on over 500 projects including London landmarks such as the Heron Tower, the Shard, BBC, Doon St and 20 Blackfriars.

Hayes Davidson was the first company to build a verified methodology for planning assessment and now has a track record of more than 55 million sq ft of approved development. 

Hayes Davidson has led guidance on visualisation for planning since the publication of ‘Accurate’, a best practice guide in 2002, and has subsequently advised organisations including the Greater London Authority, English Heritage and the UK Landscape Institute. 

We advise on and prepare TVIA and visual change assessments to support planning applications. View scoping and early-stage rapid testing allow outline analysis of townscape proposals.

Volumetric and perception assessment allow developers to assess how high – or wide – they might be able to build, and we have undertaken expert witness work reporting on visual issues relating to perception and the built environment.

"I regard your firm as the best in the field and I consistently recommend you to clients as, put simply, one cannot do better than your firm; I recommended you in this case and you did not let me or the clients and team down - your work was exemplary. Your work played in my view an important part in winning the case

We are deeply interested in cities and the ongoing potential for improved forms of visual assessment. Our work explores how the eye and brain work together, sometimes in unexpected ways, to 'see' the city around us. The city is not a 2D artistic composition and planning politics are often solely focused on 'views' of the built environment. 

We employ visual science to develop more balanced methodologies by which changes to a city can be assessed, allowing a deeper and more rounded analysis than conventional 'verified' imaging alone allows. Visual science incorporates a knowledge of visual perception, human psychology, optics, and attention analysis.

This presents a reliable framework for parties involved in scoping for visual assessment. This combination of accurate visualisation and visual research provides the robust evidence required to support the largest and most complex building proposals.
