Your project is our passion! 


Edward Sykes

Master of Architecture

BSc(Hons), M.Arch


Edward joined the team shortly after completing his Master of Architecture degree at Manchester School of Architecture in 2020. He also holds a degree in Architecture and Environmental Design. Edward has experience in designing outstanding one-off homes (including Paragraph 79 dwellings*), re-use extensions and masterplanning for larger residential developments. He is passionate about creating architecture that improves the environment we live in; creating beautiful places which engage with people and creating seamless transitions between inside and outside spaces. He cares deeply about environmental and social sustainability, ensuring the end users needs are met in both the design and construction process.


 *Paragraph 79 of the National Planning Policy Framework allows new dwellings to be built in the countryside if they are truly outstanding or innovative, reflecting the highest standards in architecture.

"Karen's dedication and focus on delivering to us our beautiful home never wavered during the complex design and often technically difficult build process.


We have no hesitation in saying that had Karen not been on our 'job' we would not have the house we now enjoy living in."
