Jennifer Hobson


Jennifer has been a designer since 2003 and with Altera Design since 2012. She is passionate about helping her clients achieve their dream vision for their space since she learned at a young age how to create an oasis out of her own bedroom. Whether they are looking to enhance their area for entertaining or creating a relaxing retreat, she has the ability to facilitate making their vision a reality. She also understands that people tend to hold a very vested interest in having their home be a reflection of who they are. As a result, Jennifer is able to help people hone in on their needs and wants. By listening intently to her clients, she can quickly ascertain their needs and get them exactly what they want. When she designs a space, Jennifer focuses on the functionality of the space first, making sure that the space functions well, then adds the aesthetic details to make the space beautiful. She starts with the bones of the project, first figuring out form and function, then she layers the room with different textures to bring her clients’ vision to reality. As a result, Jennifer has won several awards:

NARI Remmies Platinum Award Residential Bath $50,001 to $75,00
NKBA Local – Judges’ Choice, People’s Choice, and 2nd Place Kitchen
NKBA Local – 2nd Place Bathroom
NKBA National – 3rd Place Medium Kitchen and People’s Choice

In her spare time, Jennifer enjoys relaxing with family and friends, whether it’s sitting on the terrace with a glass of wine or having a casual dinner at home.
