Why Most Residential Projects Go Wrong Before Design Even Begins
This article is for you if you are a homeowner, early in the process of:
Planning a custom home
Confused about where to start your project
Trying to control costs by using a budget to frame the project
Considering hiring a designer or architect to help you create an optimum solution
Introduction
Time and time again, homeowners learn the hard way thinking mistakes only happen during the construction phase of the project is a complete fallacy. The truth of the matter is that the most costly mistakes are a result of early decisions made, before the drawings are started, and then shoe-horning solutions into place during the construction of the project.
The reasons for this approach are multiple, yet, time and time again, they demonstrate a homeowner's lack of understanding of the demands of a project's true scope.
In this article, the ten most costly types of mistakes will be identified, and their impact rated as:
Major
Project show stoppers.
Severe
Recoverable, heavily cost prohibitive, design rework, and causing severe project delays. Manufactured systems such as stairs, and roof trusses are a common source of these issues.
Very high
Costly tear-outs and rework causing delays, material substitutions, and structural re-engineering. Constructability issues affecting post locations, beams impacting clearances of doors, window collisions with interior walls, and realigning structural elements like floor trusses to accommodate plumbing and HVAC components.
High
Costly, easily avoidable errors impacting manufactured components such as cabinets, fireplaces, railings, windows, doors, etc..
Medium
Substitutions due to fit, impacts livability, and interior comfort levels.
Long-term
Increased costs to offset extra cooling, heating, and lighting loads. Limited site enjoyment and livability comfort.
The good news is these types of mistakes are predictable and avoidable.
Mistake #1 Designing before understanding the building site's constraints
Impact: MAJOR
I’ve marveled at how homeowners, new or experienced, start with visions of a beautiful home, with plenty of space for their children to play by selecting a design from a plan book or using images from online resources such as Pinterest as the foundation for their dream house.
Then the long journey to look for a lot to accommodate this vision begins, often ending in frustration or significant compromise.
Low-cost bottom-feeder drafting services reinforce the fallacy this approach by offering an unrealistically low price point, fast, "permit ready drawings" homeowners quickly learn excludes any professional oversight and guidance. These types of bottom-feeder services just take your money and run, leaving you to deal with the harsh reality of a project riddled with risk and costly errors.
It happens so often, general contractors treat plans, in general, as a "suggestion" rather than the contractual documentation they are truly meant to represent between you, the municipality, and the contractor.
I know first-hand because I've had to build from drawings like those I've described. The exercise is nothing short of being a constant source of frustration, anxiety, and emotional turmoil for all parties involved. So please, stop using low cost "permit ready drawing" bottom-feeder services.
Here’s how you change becoming a victim of Mistake #1 and bottom-feeders; develop a thorough understanding of the site before you even consider drawing a single line, selecting a plan, or cutting down any trees. Unexpected issues such as drainage problems, road allowances, waterfront setbacks, mature tree preservation, and floodplain restrictions can render initial building plans unworkable, leading to abandoning final designs after significant emotional and monetary investment. One of the most expensive mistakes homeowners make is starting the design process before fully understanding the site.
Skipping site analysis before finalizing plans results in costly, unsuitable outcomes. Site realities drive decisions, and ignoring them leads to expensive errors. This article’s purpose is for you to realize you must start asking the right questions and seeking answers to the most common risks and pitfalls. Developing a detailed portfolio of information helps to avoid major setbacks, creating a workable, successful project.
Here is a partial list of key site factors that must be understood early, before you start to hire anyone to prepare drawings:
Property boundaries:
Have a recent up-to-date property survey including all existing buildings, hardscape, and topography.
Zoning bylaws (local rules governing building size, use, and location), subdivision covenants (directives limiting the material used), etc.:
Understand subdivision's covenants governing the types, styles, and quantities of materials to be used. Zoning bylaws establish building height, use, setbacks from front, side, and rear yard lot lines, and define the allowable coverage of a building on a lot.
Topography:
Use rather than fight the natural slope of the land to lower the impact of the placement, costs for remedial cut and fill, and overall complexity and expense of the building.
Lot access:
Note locations of driveways, culverts, or curb cuts. Some may be reused, others removed and rebuilt, or require new culverts in a different location altogether.
Utility service drops (points where power and other utilities connect to your property):
The locations of electrical utility poles and connection points, and whether service is underground (buried cables), overhead (lines on poles), or is simply unavailable.
Existing vegetation cover (trees, grass, etc.):
Lots may be subject to mature tree coverage or shoreline preservation requirements.
Soil bearing capacity and stability (the soil's ability to support a building's weight):
This is impossible to observe. The soil must be tested first.
Surface drainage:
After rain, use signs of standing water to gauge the effectiveness of the existing surface drainage. Ponding indicates saturation and poor drainage needing correction.
Floodplain and shoreline setbacks:
Identify nearby water bodies and local setback rules. You may not be allowed an inground pool, workshop, or accessory dwelling because of a nearby creek located several streets away.
Soil percolation rate (how quickly water drains through soil):
Impossible to observe. You have to dig a soil test pit and have it professionally tested.
Areas for parking:
Ensure adequate space is available for meeting anticipated parking requirements.
Sun and shade patterns, prevailing winds, and exposure:
Use of available sun and shade creating a more comfortable home and reduce energy costs.
Easements and other legal encumbrances (legal rights for others to use parts of your property):
These are legal rights granted to utility companies or neighboring properties. Read and understand your property’s deed thoroughly.
Other restrictions for septic, well, and surface drainage:
Septic systems must be kept at a minimum distance from property lines, excavated to a specified depth, and allocated an overall surface area based on the soil’s ability to absorb and dissipate water.
For northern climates - snow storage.
Disputes over neighbors' stockpiling or pushing snow over and onto adjacent property abound. Avoid this constant seasonal misadventure.
For existing buildings: Ask for all previous building permits issued for the property
Illegal or unpermitted work is rampant and once discovered, adds to the cost of the project to correct.
Ask yourself this question:
Do I have the answers needed to all of the above before starting to design my project?
If you answered "No" to any one of these questions, you need to stop NOW and get those answers before moving forward.
A lack of understanding of any of these key items puts your project at real risk of unanticipated costs. Simple avoidable missteps lead to inefficient and expensive construction solutions, higher utility bills, and long-term mistakes limiting the enjoyment of the property.
When you skip exploring and understanding these site realities, you guarantee revisions, cost overruns, delays, and an underperforming home. Thorough site understanding is not optional, and bottom-feeder drafting services fail to provide you with peace of mind.
Studying the site early allows for mitigating major issues. A successful design process must include developing an understanding of the land as a first step and taking the time to determine what is allowed and what is to be avoided. Contractors are not responsible for your lack of due diligence, but they do profit from it. Taking extra upfront time needed is inexpensive, necessary, and is a sound investment.
A successful design process starts by confidently answering the questions:
What is this site asking the building to do?
What restrictions define the design’s outcome?
What am I overlooking?
Skipping early site analysis locks in expensive, long-term problems. Start with an understanding the site and you lay the foundation for a home that works with, rather than against, its environment. This is the simplest and most significant step you can take for a successful low-risk and cost efficient project.
Mistake #2: Treating Drawings as a Commodity
Impact: SEVERE
A costly mistake is treating drawings as just another task, rather than leveraging the design process to test solutions. Remember: treat design as problem-solving, thoroughly explore options, and select professionals with care.
Too often, homeowners undermine projects with the belief: “We just need drawings for the permit.” This thinking ignores the vital role that design plays in achieving a livable, functional home.
This mindset limits the project by bypassing the valuable concept and schematic phases, which offer opportunities to explore solutions, assess feasibility, and ensure options truly serve the homeowner's needs.
To manage numerous options, you must test possibilities to determine what matters most. The concept phase allows you to develop and visualize initial ideas, such as comparing kitchen layouts. One with a central island and another with open flow just to see which best fits your lifestyle and needs.
Organizing similar activities minimizes conflicts within the home. Why place a noisy appliance in quiet spaces or design rooms where movement disrupts movie-watching?
These errors are common. It’s less about choosing what to do and more about recognizing what not to do.
I once reviewed a design where the homeowner would have to carry dirty laundry from bedrooms and bathrooms, through public spaces and the front door, then across the living room to the utility area behind the garage. Groceries followed a similar route: from the car, through the garage, across the living and dining areas, into the kitchen. The front entrance looked impressive, but wasn’t practical, nor did it have a convenient closet for guests’ coats and shoes.
Instead, coats went to a bedroom closet, and shoes would be left piled up at the entrance.
The garage sat on the southwest end, and large living windows faced north towards the back of the house. The street could only be seen by opening the door and stepping outside.
Plans were made just to get the permit, with no regard for daily living. When the design was examined, it failed to support practical living and activities. As a result, it was abandoned and a new design prepared to solve the fundamental problems the owners wanted addressed.
In the schematic phase, ideas from the concept stage are refined into detailed floor plans and 3D renderings. These visuals help homeowners see how spaces serve their needs, both inside and out.
It’s not just about drafting permit plans. It’s about working with someone who asks the right questions to clarify solutions early—allowing analysis before finalizing drawings.
By skipping early design stages and focusing solely on permit drawings, homeowners miss essential opportunities to make informed decisions and improve the outcomes of their projects.
Creative design often comes from senior team members who draw on experience and past challenges. Homeowners who skip these opportunities miss out on valuable guidance offered by working with seasoned professionals.
Homeowners should choose experienced, insured professionals. Verify credentials and insurance, ask for references, and review past work. Industry associations can help recommend qualified experts. Careful selection ensures quality guidance and avoids mistakes.
Well-crafted designs are built upon:
Understanding the problem(s) you are trying to solve
Exploring options and select the best fit.
Testing solutions to ensure they suit your lifestyle.
Protecting your investment by making wise, well-informed decisions.
In summary, homeowners should focus on defining their problem, exploring and testing solutions, and selecting experienced professionals to work with. Strategic decisions throughout the design process ensure high-quality outcomes and protect investment, resulting in a functional and satisfying home.
Mistake #3: Making the Contractor Solve Design Problems
Impact: VERY HIGH
Contractors are essential to construction projects, but if they have to solve design problems during the build, it often raises costs and affects quality. To prevent this, architects can take proactive design steps such as ensuring thorough documentation and early coordination with all stakeholders. By addressing potential design issues before construction begins, architects can help minimize on-site decisions that increase costs and compromise quality.
Contractors are skilled at following clear instructions, but they are not prepared to:
Analyze how choices will affect long-term performance.
Redesign building parts while construction is underway.
Look at moisture and temperature risks as a whole.
Balance the architect’s vision with building science needs.
If design questions are not answered in advance, people on site have to make quick decisions, often based on cost and time constraints. For example, if the specific requirements for window placements and sizes are not clarified during the design phase, contractors might choose standard-sized windows to save time. This decision, made under pressure, can disrupt the overall aesthetic vision and affect the building's energy efficiency.
This often leads to:
Simpler details that can reduce how long things last,
Changes to the building envelope just to keep the project on schedule,
Last-minute material swaps that affect how the building performs,
Different trades do things in different ways.
To get the best results, design questions should be settled before construction starts. Architects can use best practices such as thorough design reviews and coordination meetings with all stakeholders to ensure clarity and address potential issues early. These practices clarify expectations and provide contractors with the information needed to execute the project smoothly.
A good design gives contractors:
Clear instructions for building parts,
Specific goals for how things should perform,
Fewer unexpected issues,
And fewer changes during the project.
Design should not be left to figure out during construction.
When contractors have to solve design problems, homeowners end up paying more at first and later, whether it’s for comfort, maintenance, or durability. Unresolved design issues can negatively impact a building's energy efficiency by allowing thermal bridging or inadequate insulation. Moisture control can be compromised, leading to potential mold growth or structural damage. Additionally, the building's structural integrity may be compromised, leading to more frequent repairs and a shorter lifespan. Addressing these design problems early ensures long-term benefits for homeowners.
