Founded in 2010 by architects David Lewis and Mark Thornton, DLMarklet began with a simple mission: to create exceptional house designs that combine aesthetic beauty, functional efficiency, and sustainable principles for the UK market.
What started as a small architectural practice in Bristol has grown into one of the UK's most respected providers of house project designs, with over 500 completed projects across England, Scotland, Wales, and Northern Ireland.
Our name, DLMarklet, derives from the initials of our founders (DL for David Lewis and Mark) combined with "let" from the word "outlet" – representing our vision to be the premier outlet for quality house designs in the UK.
