They say knowledge is power. Knowledge beforehand of the limits of zoning, codes, and finances can help streamline a project and reduce headaches and surprises further down the design and construction process. We have helped hundreds of clients create and determine the feasibility of their proposed project, providing them with the knowledge they need to secure financing and fund raising goals long before a shovel hits the earth.

Historical properties can be challenging. We have vast experience working with historical structures, including modernizing, new additions and interior renovations. We will make sure that the finished project respects the original design and provides new life for the future.

Many people think architects only design the exterior of a building. Not true… DeLizzio Seligson has completed hundreds of interior renovations in every aspect from commercial, educational, and healthcare to residential and community. We will work with you to design or redesign a space that will fit your needs, and be both functional  and beautiful.

Fund raising will often be the longest and hardest part of any proposed construction project. We have years of experience assisting hundreds of clients in developing the right marketing materials to quickly and easily communicate your project to potential donors or investors. DeLizzio Selisgon produce all our photo-realistic or artistic renderings in house, making sure that what you receive accurately represents your project.

Architecture does not stop at just the structure. We offer full interior detailing, from stained glass windows, custom designed furniture and furnishings, down to artistic wall hangings.
