The Studio

The Elysian Hotel, which is featured in our portfolio, won numerous awards largely due to the work of project designer Santi Alaysius. The Elysian Hotel was named the #1 hotel in the USA and the #7 hotel in the world by Conde Nast Traveller, and was featured in Elle Magazine in the USA.


Peter Dreier was featured in Angie's List Magazine in March 2010 as an expert in why you should hire an architect as opposed to just a contractor for your renovation project.
