Is DIY interior design really the most cost-effective way to transform your home? We've worked with many clients over the years who watch HGTV shows and think it's easy. But here's the thing: while it allows for control and the chance to express your creativity, TV shows, online tutorials and social media may make it seem more simple than it truly is.

Acting as your own interior designer requires preparing your own project budget, managing all items to be selected along with quantities and rough-ins, communicating design and installation details with skilled tradespeople, and ensuring successful management of all purchasing, stocking, and deliveries to prevent project delays.

From purchasing mishaps to aesthetic disasters, these missteps can lead to significant financial losses and long-term dissatisfaction with your living environment. Remember, poor design choices are something you’re going to have to live with and look at every day. Can you really afford to gamble with something as crucial as the comfort and beauty of your home?

What is Interior Design?

Interior design involves more than just choosing furniture and accessories. It also includes carefully selecting permanently installed items like plumbing fixtures, cabinetry, tile, and decorative lighting. There are typically hundreds of different parts and pieces that need to be specified, ordered, detailed, and coordinated with the skilled subcontractors who will be installing them.

The Downsides of DIY

The value of hiring an interior designer and general contractor that understands your vision is widely underestimated. The initial investment in professional services often results in long-term savings by preventing costly mistakes and guaranteeing top-quality outcomes. Before diving head first into a DIY project, consider asking yourself the following questions:

Do You Have The Expertise?

Professional designers refine their skills through rigorous training and extensive field experience. Their experience allows them to consistently create beautiful, timeless spaces and to create accurate, to-scale drawings, to communicate their design to necessary installers. Are you able to create these drawings and coordinate installers work successfully, or will you find that work needs to be redone?

Can You Procure the Highest Quality Materials at the Best Prices?

Interior designers have exclusive access to premium materials and furnishings that are often unavailable to regular consumers, ensuring both durability and impressive results. Their established connections with suppliers and contractors enable them to negotiate better prices and ensure timely delivery—crucial advantages if you're working within a tight budget or timeline.

At Letter Four, we approach finish and fixture orders quite differently from other firms. We request permission from clients to charge their credit cards directly for these items and provide detailed receipts and order records. This method allows us to pass our savings on to you without any markup while you also earn valuable credit card points or miles.

By leveraging our industry connections and transparent payment process, we deliver greater value while maintaining complete transparency throughout the procurement phase.

Can You Manage Your Time And Stress?

By handling all the design and coordination work, designers free up your time and reduce the stress of managing a project on your own. You’re instead able to focus on the fun part… approving all of your favorite items! They come equipped with the experience and expertise to handle any unexpected challenges that may arise during the design process, saving you from unnecessary headaches. Additionally, designers have access to a network of trusted suppliers and contractors, making it easier for them to source materials, create build-outs that are custom, and oversee the installation details. This can result in a smoother and more efficient project timeline. 

If you attempt to act as your own Interior Designer you will need to plan for items that have longer lead times, for example. If that tile you love will take 12-14 weeks to be fabricated, what effect will that have on your overall project schedule? Will you need to extend the time you’ll be staying in your expensive temporary housing?

Do You Know The Areas To Focus On To Increase Your Home's Value?

A well-designed space not only looks good but also adds value to your property. Designers know how to maximize functionality and aesthetics within your budget. They can suggest strategic upgrades and improvements that have a high return on investment, such as kitchen and bathroom renovations or enhancing curb appeal. By investing in these areas, you can potentially increase the resale value of your home.

Are You Familiar With The Latest Design Innovations?

A good designer can introduce you to new materials, technologies, and sustainable design practices that can enhance the functionality and efficiency of your space. They don’t make decisions based on what's trendy or purchase items just because they look nice or just because Susan down the block has one. Professional designers take a logical and practical approach to ensure that you don’t waste money on things that will go out of style a couple years down the road.

Avoiding Costly Errors in Design and Execution

A survey by NBC revealed that 63% of Americans who attempted DIY home improvement projects experienced regret. Moreover, one in three ended up hiring a professional to fix or redo the work! 

These figures highlight a critical insight into the challenges faced by many homeowners like yourself. Here are a handful of reasons for their widespread regret:

Underestimating Complexity: Embarking on a DIY project with enthusiasm often reveals that tasks are more intricate than initially anticipated. Interior design requires careful attention to detail. For example, when ordering tile, ensuring you purchase the correct quantities is vital. If you don’t order enough you’ll need to order more, resulting in project delays and sometimes costly freight charges. Do you know how the tile is going to be trimmed out? Are you using bullnose or liner tiles? Or maybe it’s a more modern installation which necessitates Schluter? Will you have a niche in your shower? Do your shower controls come with a rough-in valve? If not, make sure that you get the correct valve or your plumber and maybe even your tile installer will be re-doing work.

Time Constraints: Balancing work, family, and other responsibilities can make it difficult to dedicate sufficient time to complete your project properly. When you hire a professional, you’re paying them to do their job without putting your life on hold.

In light of these challenges, it's no surprise that many individuals choose to hire professionals after attempting DIY solutions. This trend underscores the value of expert intervention in achieving satisfactory, long-lasting results.

The Financial Consequences of Mistakes

Mistakes in your design choices, miscalculated measurements, or improper installations can have significant financial consequences:

Incorrect Measurements: If you make even one small error when measuring your space for furniture or fixtures it will lead to purchasing items that just don't fit, resulting in more wasted time, money and materials. If you need to return something because it doesn’t fit, it's possible that you will be charged a restocking fee of 20% or more.

Poor Material Selection: Not all materials are the same. Choosing the wrong type or quality can not only affect the appearance but also the durability and lifespan of the look you seek to accomplish for your home. For example, you wouldn’t want to use Limewash wall paint in your kid’s bedroom or hardwood flooring in your bathroom. It’s also important to note that aside from financial consequences, poor material selection can also reduce your indoor air quality and have a negative impact on your health.

These are not mere hypotheticals; each mistake carries its own risks—the specter of escalating costs, wasted time, or unsatisfactory outcomes haunting every corner of your ambitious endeavor. 

By hiring an interior designer you can mitigate these risks, ultimately saving you money by avoiding the financial woes associated with do-it-yourself designing.

The Value of Professional Expertise

Hiring an interior designer opens up opportunities that aren't available through DIY methods. One significant advantage is gaining access to their trade discounts and exclusive resources. Designers often have insider knowledge of upcoming sales or clearance events by vendors that aren't advertised to the public. This allows them to secure top-notch items at unbeatable prices, passing those savings directly onto you. 

Trade Discounts

Professional designers typically receive discounts on a wide range of products, from high-end furniture to quality fabrics and essentials like tile, cabinets, plumbing fixtures, and lighting. These trade discounts can often be as much as 5-25% off retail prices, making it possible to afford more luxurious items that might otherwise be out of reach. These savings can significantly add up over the course of your project.


Beyond just saving you money, designers also have access to exclusive resources not available to you. This includes:

Specialized Craftsmen: Access to skilled artisans who can create bespoke pieces tailored to your space.

Advanced Technologies: Cutting-edge design tools and technologies that streamline your project’s execution.

Let’s imagine the scenario where you're looking for a specific type of Italian marble for your kitchen countertops. A professional designer can leverage connections with suppliers to source this material at a reduced price and ensure its authenticity. Without these connections, a DIY attempt could lead to paying full retail prices or even falling prey to counterfeit materials.

When weighing the hidden benefits of hiring an interior designer against the seemingly lower upfront costs of DIY, these trade connections and exclusive resources significantly tip the scales in favor of professional help. The potential for better pricing extends beyond just acquiring materials; it encompasses every facet of your project, from labor costs to specialty items.

Investing in a professional isn't just about immediate cost savings; it's about the long-term value and quality assurance that comes in making this decision. 

Making the Most out Your Space

Hiring an interior designer offers hidden benefits, particularly for challenging spaces. Interior designers have the expertise to maximize every inch, ensuring no space is wasted. Every corner serves a purpose and looks good while doing so.

Key Areas Where Professionals Excel:

Space Planning: Designers are great at creating layouts that improve the flow and functionality of a room. They can turn awkward corners into useful areas like reading nooks or storage spaces.

Custom Solutions: Small or oddly shaped rooms often require custom furniture and built-in features. Designers have access to specialized cabinets and furnishings that perfectly fit these unique spaces.

Multifunctional Rooms: Experts understand how to integrate pieces that serve multiple purposes, such as furniture and lighting fixtures for home office or guest rooms that enhance productivity and comfort.

Examples of Effective Space Utilization:

Vertical Space: Designers often make use of vertical areas for storage by adding wall-mounted shelves, lofted beds, or tall cabinets.

Light and Color: The strategic use of light colors and reflective surfaces can create an illusion of more space. Professionals know how to play with these elements to make a room feel airy and open.

Top 5 Common Mistakes of DIY Interior Design

1. Not Having A Realistic Budget: More often than not, DIY projects end up costing way more than anticipated due to unexpected expenses, overspending on certain items, and costly rework done to repair errors made in the process.

Say you plan to renovate your primary bathroom and set a budget of $20,000, including contractor fees. However, as the project progresses, you realize you didn't properly prepare an accurate budget before you started placing orders. Maybe you decided to have your double vanity cabinetry custom made rather than finding something off-the-shelf. This vanity could have cost you $3,500 or less, but the custom cabinetry is $4,00 alone and you need to purchase a full slab for the counter, as well as two sinks, faucets, and drains. Now you’ve spent half of your budget on just the vanity and don’t have enough left over for the soaking tub you’ve been dreaming about.

2. Neglecting to Properly Vet Contractors: If you don’t dig into your contractor’s skill set, communication style, and billing practices, as well as verify proper licensing and insurance you will most likely hire someone who isn't a good fit for your project, leading to delays, subpar workmanship, and even higher costs to fix their mistakes. It's important to thoroughly vet multiple potential contractors, check their credentials, past work, and references to ensure they're qualified and reliable to complete your project to the level of quality you expect.

For example, you decide to just hire the first contractor you talk to for the remodel of your bathroom. Sure, they seem inexpensive, but if the tile work needs to be redone, and they didn’t pull the proper permits or have inspections, you could end up needing to redo all of the work, more than doubling your costs. 

3. Unrealistic Timeline Expectations: DIY interior designers tend to set overly ambitious timelines, failing to account for the comprehensive planning, execution, and unforeseen challenges inherent in home improvement projects. For instance, envision a scenario where you aim to completely renovate your kitchen in two months, overlooking the complexities of coordinating contractors, sourcing materials, and addressing unexpected issues like plumbing or electrical problems.

The new cabinets alone can easily take 4-6 weeks to arrive on-site. You’ll need to install those before installing the sub-tops. Then your countertop fabricator will take their measurements, fabricate, and install. This means that just cabinets and countertops could easily take up the entire project schedule you’ve allotted.

4. Poor Quality Materials: Choosing low-quality materials or furnishings to save money can compromise the durability and overall look of the design.

For example, to save money, you purchase inexpensive materials for your high-traffic kitchen area and instruct the contractor to install them. Within a few months, the flooring starts to peel and warp, making the entire kitchen look cheap and requiring an expensive replacement much sooner than anticipated.

5. Limited Resources: DIY designers may struggle to find the resources, tools, or materials needed to bring their vision to life, especially if they have limited access to suppliers or specialty items.

Let’s say that you want to create a custom built-in for your living room. There are specific dimensions that you need to work with for the built-in to properly incorporate the storage you need, display specific items, and fit around your existing fireplace and mantle. You’re unable to source off-the-shelf storage solutions and don’t know a skilled custom cabinet maker. How are you possibly going to realize your vision without an expert?


Yes, DIY projects offer creative freedom and a sense of accomplishment but more often than not they will come attached with unexpected financial burdens, time commitments, and stress. So, hiring a professional designer isn't just about outsourcing work; it's a long-term investment in your home's value and your personal well-being.
