Jillian Mitchell

I am a Chartered Architect and Director at Lomas and Mitchell Architects.  I enjoy designing low-energy, sustainable and healthy buildings.  Our work is about much more than simply creating beautiful designs; we work hard to make sure your house becomes a home.  This ‘client-centred’ approach is key in all our work.  Our successes with Paragraph 79 projects show the value of working with a Chartered Architects Practice on your custom build.
