MEP Engineering

Integrated building systems designed for performance, coordination, and full alignment with architectural intent and California code requirements.

Let’s talk

MEP engineering at Lumignus is not treated as a late-stage technical overlay. It is a core component of building design that directly influences spatial planning, structural coordination, energy performance, and long-term functionality.

Mechanical, electrical, and plumbing systems define how a building actually operates. When poorly integrated, they create conflicts, inefficiencies, and costly redesigns during construction. Our approach prevents this by embedding MEP coordination into the design process from the earliest stages.

We develop systems that are not only code-compliant, but structurally and spatially coherent with architecture and engineering as a unified framework.

In California’s regulatory environment, MEP design must also align with strict energy requirements, including Title 24 compliance, ventilation standards, seismic considerations for utilities, and jurisdiction-specific approval criteria. These constraints require precise coordination between disciplines rather than isolated system design.

Whether for residential developments, multifamily housing, commercial buildings, or tenant improvements, our MEP engineering ensures that all building systems function as a single integrated structure rather than disconnected components.

Our services are ideal for:

Systems as Architecture

At Lumignus, MEP engineering is treated as an extension of architectural logic rather than a separate technical layer.

Every system must respond simultaneously to:

  • spatial constraints and architectural intent
  • structural coordination and routing feasibility
  • California energy and building codes
  • construction sequencing and installation logic
  • long-term maintenance and operational efficiency

By integrating these requirements early, we reduce system clashes, minimize redesign cycles, and ensure smoother transitions from design to construction.

MEP systems become part of the building’s architecture, not an afterthought imposed on it.

Integrated Coordination Approach

Our MEP engineering operates within a multidisciplinary workflow that includes architecture, structural engineering, civil design, and permitting administration.

This integration allows system design to evolve in parallel with all other disciplines, ensuring alignment at every stage of development.

Instead of isolated consultant outputs, we maintain a coordinated process where mechanical, electrical, and plumbing systems are continuously validated against architectural constraints and regulatory requirements.

This results in fewer conflicts during plan check, fewer revisions during construction documentation, and more predictable project delivery.

Our Core Principles

Safety

Every project is designed with structural integrity, seismic resilience, and life safety as top priorities. By integrating architecture and engineering from day one, we ensure not just a beautiful building—but a safe one for everyone who lives, works, or visits.

High Standards

Even on complex sites—steep slopes, tight zoning, or high-risk areas—we maintain full control over technical and regulatory details. The result? Fully permitted, code-compliant, and constructible designs that meet the highest professional standards.

End-to-End Support

We’re with you from initial feasibility through final construction. Need a zoning check on a weekend? A quick BIM coordination review? We’re available when it matters—because your timeline doesn’t stop at 5 p.m.

We worked with Lumignus on two projects—an ADU conversion and a one-bedroom addition with a full remodel of our main house. Ilia, Sasha, and Kevin were great to work with throughout the process.Despite tight deadlines and challenging winter weather, both projects were completed on time and within budget. Communication was clear, the quality of work was excellent, and we are very happy with the results. We highly recommend Lumignus for any construction or remodeling project.

I had a fantastic experience working with Ilia and Kevin. We hired their company for a kitchen remodel, ADU construction, and landscaping project, and the results exceeded our expectations. Everything turned out even better than we imagined. The pricing was fair, communication was great, and the entire process was smooth and stress-free. We are very happy with the final outcome.

We bought a 3-bedroom house from the 1960s that was in very poor condition. Lumignus first prepared a feasibility study and then helped us transform the property by adding a second floor with 2 bedrooms and 1 bathroom, plus a guest house.They handled everything from architectural, structural, and MEP plans to permits and construction. The entire process was smooth, and we are very happy with the result. Highly recommend!

We had a clear vision for what we wanted to create with our guesthouse, and from the very beginning Kevin really understood what we were looking for. Not only did he listen to our ideas, but he also brought creative suggestions and even better solutions that elevated the final result.Kevin was always responsive, straightforward about what was possible, and kept everything moving without delays. We truly appreciated the communication, professionalism, and attention throughout the process.

I had the pleasure of working with Josh, Ilia, and Lois on the build-out of our new dermatology and laser medical office in West LA, and I couldn’t be happier with the outcome! From start to finish, their professionalism, dedication, and attention to detail were exceptional — every part of the office was built to the highest standards.They not only created a beautiful, functional space but also maintained excellent communication throughout the entire process. Thank you for an outstanding job!

Lumignus did an incredible job on my ADU. The entire process went smoothly — they clearly know their work. I had lots of questions along the way, and they patiently explained everything in detail. The final result exceeded my expectations — it looks solid, clean, and exactly the way I wanted. Highly recommend!

If I could, I’d give Ilia 10 stars instead of 5! He did double the work at just a third of the price compared to other architects I spoke with. His team was incredibly responsive, always available to address my questions and concerns. They were just as driven as I was to get my plans approved. Thanks to Ilia, navigating the challenging process with the City of Beverly Hills became a manageable experience. Thank you!

I highly recommend Lumignus for their talented team of architects. We hired them to design plans for remodeling our kitchen and bathrooms, as well as creating a new master bedroom and bathroom by converting an existing space. After our initial meetings, they quickly understood our design preferences, and the 3D renderings looked fantastic. The team was professional, easy to work with, and delivered high-quality work. Their customer service was exceptional—they were very responsive and also took care of filing all the necessary permits.

To start, I didn’t originally hire Lumignus—my previous contractor did. However, after firing that contractor due to various issues, I decided to continue working with Lumignus. I needed engineering support to permit previously unapproved work on a 2,300 square foot shop. The county required those permits before issuing approval for our interior remodel, which included removing a load-bearing wall, eliminating a kitchen soffit, and more. The process was complicated, and the county’s requirements were often difficult and at times seemed unreasonable. Beatrice worked closely with my new contractor, and together they managed to address all of the county’s demands. I'm very grateful for their help—thank you both.
