Our commercial building project was guided by a commitment to environmental responsibility and long-term energy savings. To minimize our carbon footprint and hedge against rising energy costs, we integrated a range of high-performance technologies, including a geothermal system and rooftop solar panels. This dedication to sustainable design earned recognition from NARI, Qualified Remodeler, and Professional Remodeler, with multiple awards for innovation, green remodeling, and commercial interiors.
To maximize energy efficiency, we commissioned an energy consulting firm to analyze numerous strategies—from high-performance glazing and enhanced roof insulation to occupancy sensors and daylighting controls. Based on their recommendations, we upgraded insulation with 5" polyisocyanurate foam under a reflective white roof membrane and added Icynene insulation to perimeter walls, creating a tight thermal envelope. Our design also incorporated lighting upgrades and smart sensors, yielding measurable energy savings and short payback periods. While we confirmed that the building’s shell and core would qualify for LEED certification, we opted not to pursue formal certification to avoid additional costs and delays.

When you’re planning a remodeling project, start thinking early about how you’ll finance the project. The scale of the project that you can undertake will be directly influenced by the amount of money available. You can complete a Feasibility Study to see if the project can be completed within your budget. If your remodeling plans are ambitious or expensive, you can consider creating a Master Plan to complete your project in phases–perhaps over a period of years. Different methods of paying for your remodeling project include cash, a home equity line of credit, cash-out refinancing, and loan to future value.
Design Build is a business model for the execution of architectural and construction projects. This model puts both architecture and construction in-house in one company that is responsible for the entire process. Design Build is a commonly used term in the industry, but not all design build firms are the same. Every firm is set up a little differently. At Landis, we have architecture, interior design, landscape design, permitting, construction project management, carpentry, plumbing and electrical all in-house. We have designed our model to provide a truly full-service experience for our clients.
The answer to this question will be variable depending on the scopes of work you are looking to complete, as well as the jurisdictions having input over your home's renovation. Generally, our renovation projects take between 10-14 months. Roughly half of this time is spent in design and permitting, and the other half is active construction.
The permits that will be required to complete your project will depend on the scopes of work that you are looking to complete and the jurisdictions in which your home lies. There are several different permitting considerations for residential construction projects including but not limited to zoning, historic, CFA, DOEE, DDOT, etc. At Landis, we have a team of in-house permitting experts who will manage the entire permit process on your project.
There are several variables that contribute to the cost of a construction project. At Landis, our architectural fees are 12% of the estimated construction costs. In addition to this fee, depending on the scope of work for your project, there may be additional fees associated with the design and permitting of your project (engineering, historic approval, etc.) For a more detailed list of construction costs, by project.
