What We Do

We strongly believe that the spaces in which we live, work, and play have a significant impact on our overall wellbeing and quality of life. That’s why we are dedicated to creating environmentally responsible, functional, and visually stunning structures that provide long-lasting value.

Our Master Planning services aim to provide clients with a comprehensive and adaptable document that will guide them through program development and growth. 

At LTA, we offer a comprehensive range of services that go beyond simply selecting colors. We understand the significance of attention to details, and our services are tailored with a careful focus on each client’s specific needs.

Value engineering is an essential aspect of any construction project. At LTA, we strive to deliver outstanding outcomes while keeping costs in mind. We consider a project successful when we can minimize expenses during the design process and not after the bidding.

Programming is a critical stage that enables us to establish a systematic approach, outline client goals, and create a foundation for decision making. Without proper programming, we risk overlooking important details that could impact the project’s success.

Our team is committed to ensuring that all of our projects comply fully with the Building/Life Safety Codes, State Fire Codes, and ADA Design Guidelines. Additionally, we recognize the significance of closely collaborating with zoning and planning officials to ensure that all regulations are met.


We are always on the lookout for new opportunities. If you are interested in our services, please don't hesitate to contact us. Our principal will get in touch with you to discuss the proposal process. Contact us today so that we can start working towards bringing your vision to life.
