When embarking on the journey of building a new home or ADU (accessory dwelling unit), one of the initial decisions to be made is whether to choose a stock house plan or go custom. Both options have their benefits, but understanding the differences between them is crucial in making an informed choice. Let’s explore the contrasting characteristics of stock and custom house plans, highlighting their unique benefits and considerations. 

Aka. Let's make a list of pros and cons for you.

Stock House Plans: Practical and Convenient

Stock house plans, also pre-designed or pre-drawn plans designed by architects, architectural designers and draftsmen. These plans are available for purchase and are designed to suit a wide range of tastes and preferences.

Pros:

• Cost-effective: Stock house plans are generally more affordable compared to custom designs, as they have already been created and can be sold multiple times.

• Time-saving: Since stock plans are readily available, all you have to do is search size, style, number of beds and baths, etc. and find one that suits you and your family's needs. Apart from possible plan changes, construction can commence sooner as the plans have already been developed.

• Proven designs: Stock house plans are typically based on successful designs that have been built and lived in by others, ensuring their functionality and practicality.

Cons:

• Outdated Designs: Most stock plans were designed in the 80’s and 90’s making the majority available online outdated, lacking in character, with floor plans that do not align with the way we live today and current construction methods. Many of these plans have been overused, resulting in a lack of uniqueness and individuality for homeowners looking for a distinctive home.

• Code Consideration: Stock plans don’t always adhere to provincial/state building codes and rarely to your city’s specific bylaws. In addition, your project will likely require a site plan. While stock plans are marketed for their time-saving abilities and streamlining the purchase-to-permitting process, most require additional information or changes.

• Limited customization: While some modifications are possible, stock plans generally offer less flexibility in terms of layout, room sizes, and architectural style. Customization is generally available but that’s going to cost you extra. In cases where changes aren’t possible, or you want to make so many  changes it’s an entirely different home, you may want to consider starting from scratch and going custom.

Custom House Plans: Tailored to Your Vision

Custom house plans are designed from scratch to meet the specific needs and desires of the homeowner, and account for specific site conditions. This option provides the opportunity to create a unique home that perfectly aligns with your lifestyle and property.

Pros:

• Flexibility: With custom plans, you have the freedom to choose your desired architectural style, layout, room sizes, and unique features that cater to your specific lifestyle.

• Personalization: By working closely with an architect/ural designer, you can conceptualize a home that reflects your individual style and needs.

• Optimization: Custom plans enable you to maximize the use of available space and account for specific site conditions to maximize additional benefits, such as topography, views, and orientation for improved energy efficiency.

• Collaboration and Creativity: Creating custom plans involves close collaboration between the homeowner and the architect/ural designer, fostering a creative partnership and often ensures that the final design meets your vision.

Cons:

• Budget considerations: While custom house plans offer unparalleled flexibility, it's essential to consider the higher costs associated with the design process, architectural fees, and potentially longer construction timelines depending on the difficulty of the build.

• Timeline: Stating the obvious, custom house plans do take a lot of time. While it may take you some time to find the right stock plan, it doesn’t compare to months of understanding site conditions, bylaws, homeowner needs/wants, revisions, etc. 

Deciding between stock house plans and custom house plans ultimately depends on your priorities, budget, and desired level of involvement in the design process. Stock plans offer convenience, affordability, and proven designs, making them ideal for those seeking a practical solution. On the other hand, custom plans provide the opportunity to bring your unique vision to life, tailoring every aspect of your home to suit your specific preferences.

Whichever path you choose, investing time in research and consultation with professionals will help you make an informed decision that aligns with your dream of building the perfect home. Remember, the key is to find the balance between practicality, personalization, and budget considerations to create a home that not only meets your needs but also brings joy and comfort for years to come.
