About Us

Added Value Architecture Ltd. was founded by residential architect, Karen Harper. Having worked in the construction industry for almost 20 years, Karen has gained a wealth of experience in temporary works, structural engineering and architecture. She has worked for several award-winning RIBA Chartered practices in Cheshire.


Karen has a passion for residential architecture and a talent for reconfiguring internal layouts to make spaces work more effectively. She takes pride in offering solutions which challenge preconceptions and add value, not just square footage.

"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."
