Architecture
We design clear, buildable restaurant and retail spaces that work for single sites or large multi-site rollouts, prioritizing ease of construction, brand consistency, and lasting value.
"Great architecture is not just about design, it is about clarity. Our job is to create documents that translate seamlessly from concept to construction so every project is built as intended."
- Prototype design and program documentation to support scalable rollouts
- Schematic design through construction documents with a focus on clarity and buildability
- Ground-up new construction and site-adapted design
- Remodel, renovation, and brand refresh programs
- Brand standards coordination to maintain consistency across locations
- Construction administration, including RFI responses, submittal review, and site observation
- BIM / Revit documentation for coordinated, efficient delivery
- Multi-site rollout documentation to support speed and repeatability
MEP Engineering
Our in-house MEP engineers partner closely with our architects and civil team to deliver smooth, coordinated restaurant and retail projects that support operations, efficiency, and local code compliance.
"When MEP is disconnected, issues show up in the field. By integrating engineering from the start, we reduce risk, improve clarity, and keep projects moving forward without surprises."
- Mechanical, electrical, and plumbing systems designed in coordination with brand and operational requirements with regional site adaptation applied across national programs
- Food service and kitchen coordination, including equipment layouts and rough-ins
- Refrigeration and specialty system coordination for restaurant and grocery environments
- Utility planning and existing conditions verification, including site visits and field coordination
- Petroleum coordination for c-store and fuel-based programs
- EV charging infrastructure, parking lot lighting design and photometrics
- Equipment, power, utility and fire alarm coordination across all disciplines and building types
- Local jurisdictional and energy code compliance, including Title 24, CalGreen, and ASHRAE
Civil Engineering
We produce the civil drawings, documentation, and coordination needed to move multi-site projects through approvals, from early feasibility through permit-ready civil plans.
"Civil is often the first step in unlocking a site. By working side by side with our Architecture, MEP, and Development Services teams, we streamline approvals and reduce surprises before they impact the project."
- Site feasibility and constraints analysis to inform early decision-making
- Civil design and permit-ready drawings aligned with local requirements
- Utility coordination, including existing conditions and service planning
- Stormwater management and drainage analysis
- Land development planning and site layout support
- Jurisdiction-specific compliance and entitlement coordination
- Multi-site civil standardization to support repeatable rollouts
- Early risk identification before design is finalized
Permitting
25+ dedicated commercial development professionals and over 75,000 permits approved across the country, Interplan delivers the scale, experience, and jurisdictional insight needed to keep projects moving.
Most A/E firms outsource permitting. Ours is in-house. Our Development Services team provides proactive coordination, stakeholder collaboration, submittals, and tracking so permit approvals don't stall your schedule.
"Due diligence and Permitting are not side tasks for us; it is a dedicated discipline. Understanding the process up-front and effectively managing the schedule to ensure the project stays on track is why our team stays focused and engaged from start to finish."
- AHJ coordination and direct engagement with local jurisdictions
- Entitlements and zoning coordination
- Permit applications, submittals, and resubmittals
- Proactive permit tracking, follow-through, and approval management
- Local jurisdiction relationship management to help navigate approvals
- Site Investigation Reports (SIRs) to identify risks, develop timelines, and uncover pre-development process fees before submittal
- Coordination with contractors post-issuance to support construction kickoff
- Nationwide programs. Local execution. Permits that keep pace with your rollout.
Project Management
We guide projects from Kickoff to Closeout as an owner's trusted partner, providing project and construction management oversight that drives alignment, reduces risk, and coordinates every discipline so projects move forward with clarity and purpose.
"Our role is to represent the owner's interests at every stage, bringing clarity, alignment, and accountability across every discipline so projects move forward with purpose without unnecessary friction.""
- Owner’s representative model focused on protecting your goals, budget, and schedule
- Cross-discipline coordination across architecture, engineering, permitting, consultants, and contractors
- Schedule development and milestone alignment to keep projects on track
- Early risk identification and proactive issue resolution
- Clear communication, reporting, and stakeholder alignment
- Defined accountability across all project partners
- Construction phase oversight supporting alignment between owner, contractor, and design team
- Built for multi-site volume. The more locations, the more valuable the system.
Interior Design
We craft interior environments that bring brand vision to life, enhance the guest experience, and support efficient operations across every location.
"Our role is to take a brand's vision and turn it into a space people can feel. Every detail is intentional, from the materials to the layout, to create an experience that reflects who the brand is."
- Concept design for new brands, first locations, and flagship spaces
- Brand refresh and reimagining of existing environments
- Interior finish, fixture, and material selection aligned with brand identity
- Custom fixture design and space planning
- Guest experience design that shapes flow, atmosphere, and engagement
- Integrated coordination with architecture and MEP to ensure design intent is realized
- Design documentation that translates vision into a clear, buildable outcome
ADA Services
We provide expert accessibility support, representing owners in ADA matters and conducting fleet-wide compliance evaluations to identify deficiencies, mitigate risk, and implement practical remediation without disrupting schedules or budgets.
Very few A/E firms offer ADA Services at this level. For every level of your business and retail brands, accessibility is not a one-off issue, it is a portfolio-wide risk that must be actively managed.
"Accessibility compliance requires more than a checklist. It requires a clear understanding of risk, documentation, and practical implementation that works in the real world."
- ADA compliance reviews and on-site surveys
- Fleet-wide accessibility evaluations across your full portfolio
- Deficiency identification with clear, prioritized, and concise remediation strategies
- Accessibility documentation to support compliance and legal defensibility
- Expert Witness capabilities
- Risk mitigation planning aligned with operational realities
- Owner representation in ADA-related matters and claims
- Practical solutions that balance compliance, cost, and schedule
