We provide architectural design services for residential and commercial projects. We work closely with each client and approach a project as those it was our own. We consider design options as well as construction options.


We provide mechanical, electrical, and plumbing engineering services for projects of varying scope and size. We engineer each project using best sustainable practices.  We consider first cost as well as operating cost.

Project Management

Maintaining effective and ongoing communication within our team, with our clients, and with other consultants is one of our highest priorities. We plan, adapt, and make decisions for the most cost-effective, visually-appealing, and energy efficient designs.

Construction Administration

We ensure oversight and support throughout the entire project, collaborating with all people involved through site observations and meetings.

Document Management

We help with the filing, modification, and approval process of all necessary documents during the permit process.



1. Consultation

We meet with you to develop the scope of the project evaluating any site or budget constraints.

2. Research

We perform preliminary code research and discuss any issues that might impact the design and/or budget.

3. Floor Plans

We begin developing and modifying floor plans using 3D modeling software.


4. Documents

Once approved, we transform our design into a detailed set of plans used for permitting and construction.


5. Administration

We answer questions that arise during construction, review submittals, and perform construction site visits with reports. 


We are passionate and experienced.

J. Allan Hensley, Jr. and Sherie Hensley shared nearly two decades of experience when their passion for design led them to establish their own firms. Allan founded H4 Architects in November 2011. Sherie founded H4 Engineers in September 2013. The two companies became one in February 2015.

H4 Architects and Engineers is an architectural and MEP engineering studio with over 55 years of combined experience in the construction industry. Drawing from this experience, our team listens to your needs and presents creative solutions. We are dedicated to providing attention to detail along with innovative, sustainable, well-coordinated, and cost-effective design solutions. We are not only creating projects but building long-lasting relationships.

We are family.

H4 Architects & Engineers is made up of outstanding experienced individuals who work as a team. As Dr. Dalah Halderman stated, “Individual talents get magnified many times over through the collective lens of an effective team.” It takes teamwork throughout the entire process to make a project a successful reality. 

We take our work seriously but know how to have fun as well. We are a family oriented office. We have just as much fun outside the office as we do inside. We have spontaneous lunches, build in the AIA Sandcastle, run the Insane Inflatables 5K, eat and play volleyball at company BBQs, and so much more.

Let’s work together!

We would love to turn your dream into a reality. Simply fill out this form and we will be in touch within one business day to begin discussing your project.
