==Architect-led design–build projects==
Architect-led design–build projects are those in which interdisciplinary teams of architects and building trades professionals collaborate in an agile management process, where design strategy and construction expertise are seamlessly integrated, and the architect, as owner-advocate, project-steward and team-leader, ensures high fidelity between project aims and outcomes. In architect-led design–build projects, the architect works directly with the owner (the client), acts as the designer and builder, coordinating a team of consultants, subcontractors and materials suppliers throughout the project lifecycle.

Architects lead design–build projects in several ways, with varying degrees of responsibility (where "A/E" in each diagram represents the architect/engineer):

#Architect as provider of extended services: Contracted to the owner, the architect extends his or her services beyond the design phase, taking responsibility for managing the subcontractors on behalf of the owner. The architect bears similar risk but has more control over the project than in the traditional approach or on contractor-led design–build projects.
#Architect as primary party in architect-led [[integrated project delivery]] (IPD): Again, as in working together in a joint venture, both coordinating the subcontractors to get the project built. Again, the building owner has a single contract with this joint venture. This time, the architect leads the joint venture so in supervising the subs, the contractor might defer to the architect. The architect might bear more risk than they do in the traditional approach but risk is shared with the owner and the contractor, as outlined in their agreement. An alternative approach to effectuating this delivery structure is for the architect to contract directly with the owner to design and build the project, and then to subcontract the procurement and construction responsibilities to its allied general contractor, who enters into further subcontracts with the trades. This is a difference in form, rather than in substance, because the business and legal terms of the agreement between the architect and the general contractor may be the same regardless of whether they are characterized as a joint venture or as a subcontract. It is the "flip side of the coin" of the contractor-led approach described above in which the general contractor subcontracts the design to the architect.
#Architect as full service leader of design build process: Contracted to the owner, the architect offers full service to the owner, taking responsibility for managing the subcontractors, consultants and vendors, and involving them throughout the project, start to finish, from design through construction. The architect's role shifts during the project, from designer to site supervisor (effectively taking the role of a general contractor), but monitors the project vision, and is able to call upon subcontractors' construction expertise throughout. The architect bears the greatest risk but also has more control over the project than in either the traditional approach, or in the contractor-led and other architect-led design–build projects.
