Firm Profile

Since its founding Assembledge+ has been pursuing an architecture that is driven by a commitment to collaboration and craftsmanship with the goal of creating enduring environments that are user-focused, innovative and sustainable.

We believe in the art of collaboration. The name Assembledge+ was deliberately chosen to convey the firm’s passion for “assembling” all the often-complex elements of the design process in order to produce an architecture that is precise, considered, and placed firmly on the leading edge of contemporary discourse. The + signifies an approach that looks at the whole as an inextricable combination of interrelated parts as we continue searching for better, more efficient, and innovative ways to construct modern living and working environments. In the spirit of this approach, we consistently challenge traditional limitations as to what can be achieved within typical constraints and use new technologies, materials and contemporary building techniques in the creation of an architecture that not only meets practical requirements but also inspires.


The firm is led by David Thompson, Design Principal & Founder, who was joined by his father in 2013, Richard Thompson, FAIA, as Principal of Urban Design. Together, this father-son duo continues to build upon the firm’s commitment to active collaboration and are expanding their capability to address larger-scale projects in the urban and campus environment. Our principals and talented staff from diverse backgrounds, embrace challenges and deliver both imaginative and innovative architectural and urban planning solutions. With extensive experience in the design and execution of residential, commercial and urban planning projects, Assembledge+ offers high levels of design sensitivity, technical expertise, and hands-on principal involvement to every project, large or small.


Our approach to architecture is situated within a contemporary modern design, particularly rooted in the Southern California tradition and climate.  This is an architecture that is attuned to its environment and that supports and nourishes the people for whom it, in turn, is also the environment.

We take for granted that no formula can be applied indiscriminately, irrespective of specifics.  Instead, we adhere to an architecture of pragmatic response, whereby each project is approached according to its particular character.

Our design process begins with questions. What is the program and the intent?  What is the aspiration?  These conversations are informed by a thorough analysis of the site – both of the property itself and of the neighboring community, and the client’s specific needs and aspirations.  The resulting architecture, then, combines these imperatives with materials, technology, craftsmanship, and form.

Creating enduring environments that are designed responsibly and sustainably have been hallmarks of the firm’s design culture, relying on classic strategies for the Southern California climate such as good exposure to sun and ventilation, well-insulated walls, and shaded interior courtyards; collapsing the boundary between interior and exterior; extending living spaces to the exterior.
