Our home building process has three steps: align, design and define, and build with confidence. The goal is to replace uncertainty with clarity at every phase.

• Step 1: Align. Your project begins with an honest conversation about your vision, your site conditions, your priorities and your investment range. Our team establishes realistic expectations around budget and timeline before any design work begins. This prevents the most common and costly mistake in custom home building: starting construction before both sides are truly aligned.
• Step 2: Design and define. Once expectations are aligned, we guide you through a detailed design and pricing phase. Your ideas are translated into clear plans. Selections are made intentionally. Costs are refined. All of this happens before a shovel goes in the ground, so there are no surprises waiting for you in the construction phase.
• Step 3: Build with confidence. Construction begins only when everything is clearly defined. You can rely on our team to manage scheduling, trade coordination, communication and quality control throughout the build. Your role is to stay engaged, make timely decisions, and trust the plan as your team brings your home to life.

Most of our custom homes are built on a 12- to 15-month timeline, measured from excavation to certificate of occupancy. Before construction begins, clients move through a 6- to 12-month pre-construction phase covering design, pricing, permitting and selections.

That pre-construction phase sets the foundation for a smooth build. The time invested in planning is paid back in a construction process that moves with fewer delays, change orders and surprises. We work to establish clarity early so the construction phase can proceed with consistency.

Total time from initial conversation to move-in for most clients is roughly 18 to 27 months, depending on design complexity, site conditions and permitting timelines in the municipality.

Costs will vary widely: We do not price custom homes strictly by the square foot, because square footage alone does not reflect how a truly custom home is built. Site conditions, design complexity and the level of interior and exterior finishes all have a significant effect on total cost.

Still, cost per square foot can be helpful for early estimating purposes. Most custom homes in our area fall within a general range of $350 to $500 per square foot of finished space. Our process is specifically designed to move from vague estimates to a precise, realistic number quickly so you can enter construction with a clear budget, not a fluid cost per square foot.

Factors that affect where a project lands within or outside that range include:

• Site preparation requirements (grading, soil conditions, lakefront restrictions).
• Home size and structural complexity.
• Window and exterior cladding selections.
• Kitchen and bath finish level.
• Mechanical systems (geothermal, radiant heat, whole-home automation).
• Municipality-specific requirements, including setback rules and, for lakefront properties, the 50 percent rule that limits how much of a structure on a lake lot can be rebuilt.

You don’t need to. When you work with a design-build firm, like M.J. Whelan Construction, you can rely on both design and construction services under one roof. With this approach, the two disciplines stay coordinated throughout your project rather than operating in separate silos.

When a homeowner hires an architect independently, design decisions are frequently made without full visibility into what those decisions will cost to construct. The homeowner then becomes the bridge between two teams with different contracts, different priorities and sometimes different assumptions. That creates complexity M.J. Whelan is specifically structured to eliminate.

If you have already engaged an architect you trust, M.J. Whelan will work with that architect. But before you commit to that path, a conversation with M.J. Whelan’s team costs nothing and could save you both time and money. Starting the design-build conversation early creates better collaboration, fewer revisions and a whole-home plan that is buildable from the start.

Yes, we can build from plans the client provides. However, we consistently deliver the highest level of service when our team is involved in the design process from the beginning.

When a homeowner arrives with completed plans from an outside source, our team must review those plans for constructability, local code compliance, site compatibility and budget alignment. This process that takes time and often reveals revisions that require going back to the original designer. When design and construction are handled by one team from the start, that review happens in real time, not after the fact.

If you have plans you love, bring them in. We will be direct with you about what’s required to build from the plans and what, if anything, should be reconsidered before construction begins.

Budget alignment is an ongoing conversation, not a one-time estimate. From the first meeting through the final selection, we help you understand the cost impact of each decision as it’s made, not after the contract is signed.

This alignment is key during the selection phase, when you choose finishes, fixtures and systems. A countertop upgrade, a window configuration change or a mechanical system addition each carries a dollar impact. We present those impacts clearly, with options to stay within budget, move the number up or find alternatives that deliver a similar result at a different price point. We never want to see a client surprised by a cost.

The biggest budget problems in custom home building happen when the process breaks down: when selections are made late, when design and construction are handled by separate teams, or when clients don’t fully understand the cost implications of the choices they’re making. We built our process to prevent those missteps.

Every project begins with a realistic timeline developed by the M.J. Whelan project manager based on the specific scope of work and key selections. That timeline is set before construction starts. When delays occur, due to weather, material lead times or other variables, we manage them proactively. Clients receive transparent communication, regular updates and a clear picture of next steps. The standard at M.J. Whelan is that clients should never be left wondering what is happening on their project.

M.J. Whelan Construction has been building custom homes for more than 35 years. In that time, the firm has built deep relationships with trade partners, material suppliers and local municipalities throughout the Milford and Oakland County area. These relationships translate directly into scheduling reliability, material access and a construction process that navigates permitting efficiently.

But the differentiator most clients name after the build is complete is our people. M.J. Whelan’s team understands that starting a custom home feels overwhelming, and the firm’s process is structured to replace that anxiety with clarity. Every client is guided. Every decision is explained. Every question gets a direct answer.

Our stated purpose is to create homes that change the way clients live. That is the standard every project is held to.

The most common and costly mistakes in custom home building share a root cause: process breakdown. The following patterns are most often responsible for budget overruns, delays and client frustration:

• Starting without a clear plan. Entering construction before design, pricing and selections are complete creates a cascade of change orders and cost surprises. M.J. Whelan’s pre-construction phase is designed specifically to prevent this.
• Making selections late. When material and finish selections aren’t finalized before construction begins, scheduling disruptions follow. M.J. Whelan guides clients through the selection process early so materials are available when the schedule requires them.
• Separating design from construction. When an architect and a builder operate independently, decisions made in one lane create problems in the other. The design-build model keeps both in the same lane.
• Not fully understanding the contract. The M.J. Whelan team walks every client through the contract in detail before it’s signed, because misaligned expectations at the contract stage are the beginning of a difficult project.
• Underestimating how decisions affect budget and timeline. Every selection is a cost decision. We present the financial impact of decisions as they are made, not after the fact.
