horncastle:thomas is a RIBA Chartered Practice formed in 2011 in the Isle of Man by Karen Horncastle + Martyn Thomas

Both RIBA Chartered Architects: Karen has worked in the Isle of Man for twenty years; Martyn worked for two leading architectural practices in North West England before returning home in August 2010

Both have experience working on a variety of existing and new building types, including listed and registered buildings and new buildings in conservation areas 

A belief in the value and benefits of good modern design underpins the practice's approach.  Always considering context, environment, local constraints + craft and combining design technology with an understanding of the past, horncastle:thomas retain an aspiration to find quality in the slightest of projects

In addition to the practice's current work, this website illustrates samples of work undertaken for previous employers + collaborators (as credited)
