About
Founded in 2005. Renovations, additions and custom homes across Union, Essex and Morris Counties.
Founded in 2005, Michael Robert Construction is a Westfield residential construction and design-build firm led by Mike Mroz. We bring architectural sensitivity, construction expertise and organized project management to significant renovations, additions and custom homes — built to the client’s taste rather than to a house style of our own.
How we work
New work has to connect to the structure already there — how the rooms relate, where the daylight comes from, and whether the details support the way a family actually lives. A renovation planned room by room tends to read that way when it is finished.
Proportion, materials and the design intent are respected while constructability and cost are being worked out. Mike's study of classical architecture is the reason that conversation happens on site rather than only on paper.
In our shared Westfield office, project plans are often spread across the conference table. That gives members of the MRC and EMD teams an opportunity to see a design taking shape and raise questions before the project reaches their part of the process. A conversation about an exterior window can lead to a question about a built-in, a furniture layout or a curtain panel. Bringing those perspectives together early helps us consider how the whole home will work, down to the details that make it comfortable to live in. Each project's design and furnishings services are defined by the scope the client chooses.
A dedicated project manager runs the job day to day, alongside a team of highly skilled carpenters who turn the drawings into the thing itself. Having that expertise on hand is why a detail gets resolved on site rather than deferred — pieces fit the wall they are built against, scribed to an old floor and detailed to match the trim around them.
Clear responsibilities, coordinated planning and regular communication — weekly meetings during construction, a structured feedback process, and warranty check-ins afterwards.
Roots
Mike was born and raised in Westfield and still lives there, which is less a sentiment than a working method: the towns we build in are the towns we know, the office is a short drive from most of the job sites, and the trades we use are people we have worked with for years.
He started building at thirteen, in his parents’ basement. The study of classical architecture came later, and it is the part of the background that shows up in the work — in how an addition is proportioned against the house it joins, and in what gets kept when an older home is reworked.
For about eight years he also co-owned and ran Green Energy Improvements, a New Jersey home-performance company — opening existing houses up, testing them, finding where they leaked heat and air, and measuring the result. The company is part of the firm’s history now; the habit it taught is not. Air sealing, insulation detail, where the thermal boundary lands and how the mechanical systems are sized get decided on every project while the walls are still open. How that shaped our whole-house approach.
Long-term performance
How a house performs is decided by unglamorous choices made during construction: insulation and where it goes, air sealing at the junctions that actually leak, window specification, and how the mechanical systems are sized and zoned for the rooms they serve.
Those decisions are made per project, against the building, the budget and how the family uses the house — not against a standard package. Where a project calls for a specific efficiency target or certification, that is a conversation to have during design, when it can still shape the drawings.
Two pathways
A one-stop route for the design and the build: architectural planning, project management and construction coordinated by one team.
How design-build worksBring the drawings and engage MRC as your construction partner. We collaborate with the architect and designer you have already chosen.
Building from your plansMRCxEMD
Michael Robert Construction and Ellie Mroz Design work together as MRCxEMD. EMD Construction Consulting and Furnishings are optional services available with either MRC pathway, and we welcome collaboration with your existing architect and interior designer.
After the build
Finishing a project is the start of the relationship rather than the end of it. For the homes we have built or renovated, MRC stays reachable afterwards: there is a three-year craftsmanship warranty, warranty check-ins are part of the process, and the office answers the phone once the site is clear.
It is not an open-ended maintenance contract, and it is for MRC clients. If something in a house we built needs looking at, call us.

It means understanding why a detail is there and how it relates to the rest of the house. Proportions, material transitions, trim, cabinetry and lighting should be coordinated, not resolved as isolated field choices. We bring that perspective to both design-build projects and homes designed by outside architects.
