Founded in 1977, Simpson & Brown has evolved into a multi-disciplinary practice which now also offers architecture, archaeology, architectural history, heritage consultancy and master planning services. As a medium-sized practice of seven partners and 35 staff we have the capacity to resource projects fully and appropriately. Seven of our architects are conservation accredited according to the UK national registration scheme, three at the highest level.
During its 45 years the partnership has been responsible for conserving some of the United Kingdom’s most important historic structures including universities and government buildings. The practice operates throughout the United Kingdom and internationally. All staff are committed to quality, continuing professional development and, above all, the interests of our clients. We are a collaborative office and often work alongside other practices and professionals.
Simpson & Brown enjoy and learn from projects where we work in a team to provide heritage support to other architects and designers. We have extensive experience in the classification, condition assessment and repair of heritage structures and archaeological sites. We have worked on many projects of urban and rural regeneration including projects in the UAE and in Saudi Arabia.
Simpson & Brown have worked on assessments of World Heritage archaeological sites, repairing historic structures, and interpreting them for a museum. We have worked on many situations where an understanding of the relationship between a historic site and its cultural heritage context is key to the success of the project. We have experience of all types of conservation techniques and have completed work in Britain, Canada, India, USA and Myanmar.
We have specific skills that can be applied to this project; the archaeology and heritage assessment department of Simpson & Brown has relevant Jordan Valley experience. We can provide a fully integrated understanding of the history and significance of each element and value of the site. Our experience as architects means that we can support and contribute to the design process in a collaborative way.
As one of the leading conservation specialist architectural practices in the UK, we have carried out over 1,500 conservation projects at heritage sites.
The archaeology team of Simpson & Brown, Addyman Archaeology, has extensive experience in the assessment of historic landscapes and the conversion of archaeological sites and heritage structures for masterplanning, cultural tourism, museums and national branding. We have worked on significant projects of urban and rural regeneration including over 20 projects in the Kingdom of Saudi Arabia. We have proven experience on delivering significant landscape assessments and historic environments surveys and analysis for national bodies such as the National Trust, both conducting fieldwork and assessing the significance and management requirements of complex, multi-site landscapes.
