Our vision is to bring architecture to everyone. We want the renovations of our homes and businesses to be easy, personal, and accessible. Design should bring value while reflecting the complexity of our lives. As a new service from Bright Architecture, Sixthirty provides affordable, custom design packages that brings personal and professional architecture services to small residential and commercial renovations. The design packages are priced per room, per shop, per floor area and broken out into a menu of separate design phases. By using 3D BIM (Building Information Modeling) technology, proprietary internal design processes, focusing on the customer, and leveraging our industry experience, Sixthirty re-conceives architecture as an affordable catalog of professional services with design, documentation, and project assistance packages.

"We loved working with Holly and the team at SixThirty so much that we hugely increased the scope of our work. First we just wanted a bathroom and a kitchen updated but we loved the plans and the possibility they brought to our space so much that we got designs for every space. Any renovation becomes a drag, but working with Holly and the team was very satisfying and filled us with ideas for our new space. She and her colleagues, especially Michael and Amy, were great, even though we had a million questions and wanted to know "why" for every decision. I can't recommend this service enough, especially for the ability to try out design in a small space and then get addicted and want to do more!"

Basement Remodel questions, answered by experts

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
