Letter Four Construction

Letter Four, INC. is a full service design build firm that offers the seamless integration of architecture, construction, and construction administration that addresses the diverse goals of our clients. We specialize in residential, retail, and commercial design and construction. We are committed to creating inspired, original works that are feasible and achievable given any project challenge.

We welcome all inquiries, but when we do decide to work with a new client, we want to make sure we can provide them with the time and attention their project deserves. We assess each project's scope prior to a consultation meeting to see if we can provide the client with the quality of service we give to all of our projects. Our ideal inquiries are those who are looking for architectural and construction services (preferably design-build, but can offer both separately). We do not offer "handy-man" services or assist with minimal repairs. Typical Job Costs are approximately between the range of: $200,000 - $3,000,000. Based on the recent bids on our projects, in order to achieve the results similar to those seen on our portfolio and website, your all-in budget should realistically be in the $225-$850/sf range for the finished project. However, this is exclusive of landscaping, furniture, and other soft costs.
