Want to convert your attic into a gorgeous bedroom-and-bath suite? Here are the attic master bedroom ideas you need to consider.

A home’s attic is a space whose usefulness is often overlooked by many Seattle homeowners. In most homes, it’s just dead storage space or, at best, a spot for luggage and boxes of holiday decor. But with the right design choices, your attic can be so much more!

With the careful planning and creative design, you can turn your unused attic space into a luxurious attic bedroom primary suite.

Seattle Remodel Guide: Transform Your Attic with These Finished Attic Bedroom Ideas

An attic bedroom conversion is an excellent way to expand your home’s space, but there are some important points to consider as you decide if this project is for you.

Which Should You Remodel: Your Basement or Attic?

One of the most common questions we hear from Seattle homeowners is: Should I finish my basement or remodel my attic? Converting a basement into a primary bedroom can be a great way to go. Nonetheless, there are two main reasons why you might want to opt for an attic bedroom instead: Natural light and comfort.

In our experience, the most sought-after feature in a primary bedroom for many homeowners is a well-lit, breathable space.

In our experience, many homeowners value a bright, breathable bedroom over one that feels closed in. While it may sound counterintuitive, most people find that morning light helps regulate sleep and mood, which is something an attic bedroom can provide more easily than a basement.

Unless you are careful to install plenty of windows in your basement, natural light is more likely to be limited, especially if your lower-level room has not been redesigned and rebuilt specifically as a bedroom space.

Designing the Perfect Finished Attic Bedroom Layout

Maximize Space and Storage

Storage space is another vital factor to keep in mind when planning your finished attic bedroom layout.

In most cases, attics are, by default, storage areas of large items. Existing storage space might provide a bit more square footage for closet and floor space.

With the help of an experienced interior designer, you can create a multipurpose floor plan that includes a  closet and your finished space, thereby ensuring that you still have enough storage space left post-conversion.

Choosing Your Attic Bedroom Architecture

Most attic primary suite conversions begin by redoing the attic’s collar ties so that you get more headroom. These horizontal support beams can be exposed or hidden above the drywall ceiling. (Take a look at our attic bedroom ideas section below to get a sense of which approach you like best.) If you leave the beams exposed, you will need to decide whether you prefer natural wood, which is popular with enthusiasts of a more rustic design, or perhaps something subtler.

Structural Feasibility and Building Codes

An experienced architect or structural engineer will ensure that whatever attic bedroom design you choose will not harm the structural integrity of your home. In many cases, especially in older homes, an attic conversion will leave you with a much more structurally sound home than the original. Seattle building codes require that you bring the structure up to modern standards when you tackle this type of project.

In addition to shoring up the roof, your attic floors will probably require some extra retrofitting to allow them to withstand the weight of regular foot traffic.

Finally, you also must consider access. Most attic conversions and renovations require the re-engineering of your stairway. In many cases, the stairs may need to be repositioned to allow good access between your attic rooms and the floor below.

Seattle Building Codes for Attic Bedrooms

Converting your attic goes way beyond planning your interior design. Attic remodeling is a major project that demands much from the homeowner.

It’s vital that you consult local building codes and existing attic design templates, thereby ensuring that you’re compliant with the set codes. You will likely be working with a qualified interior designer or architect who will handle permitting and design review for you.

Ceiling Codes for Attic Bedrooms

Here’s a regulatory tidbit for you: Here in Seattle, no inhabitable attic room may be less than 7 feet in either height, width, or length.

Whatever your current dimensions are, they must meet this threshold at a minimum. To meet these minimum space requirements, and add living area, you can consider a dormer addition.

A dormer is a window that projects vertically from a sloping roof. Dormers can be quite large, greatly expanding the usable square footage of the attic. Dormers are usually what make cool attic bedrooms possible.

That said, even if your attic space meets the square footage threshold, there is still a lot that has to be done to bring it up to full code-compliance including proper insulation, egress windows for safety and adequate ventilation.

Cost and Timeline for a Finished Attic Remodel

With attic bedroom remodeling, you will need to plan finances carefully and calculate every renovation expense that may arise before starting the project.

Original rough attics in older homes tend to require more work and incur more cost than redoing a previously finished or partially finished attic space in a newer home.

Cost of Attic Bedroom Remodeling Project

It can be difficult to get an accurate estimate of how much an attic conversion will cost because there are so many factors at play. However, I recommend you check out our Additions Pricing Guide for some ballpark cost estimates. You can also call other design-build companies and ask for ballpark estimates. I’ve found that the estimates published online on sites like Homeadvisor.com and other places grossly underestimate the real-world building costs we’re seeing in Seattle today.

You will have to decide how best to balance out your needs: your budget vs. the prospect of increasing your home’s value should you one day decide to put it up for sale.

The best thing to do is ensure you have experienced professionals who have prior experience with appraising attic remodeling projects.

When it comes time to sign a construction agreement, I recommend that you insist on a fixed-price contract so that you are not surprised by overages. I don’t recommend a time-and-materials type contract or just a loose estimate from a builder for a project as complicated and costly as an attic renovation, especially if it includes the addition of dormers.

How Long Does an Attic Bedroom Conversion Take?

Converting an attic into a primary attic bedroom suite is a major project. Attic conversions can take as little as two months, but typically they will take three to four months and will require several types of permits.

Your designer and builder should be able to give you an up-to-date estimate of design and construction time. Keep in mind that most reputable firms in Seattle have longer-than-usual wait times right now.

You Might Need to Retrofit a Staircase for Your Attic Room

Most attic conversions require new stairs. Ladders and steep, narrow staircases will not be sufficient if you plan to use your attic as a bedroom suite.

In most cases, you will need to devote extra space, either in the attic or on the floor below to allow for a new, not-too-steep, code-compliant staircase. In many cases, the staircase may have to be relocated entirely. 

You might also need to make some changes to the flooring and ceiling layout in order to safely and conveniently connect your attic to your main house—the ease of which will, of course, depend on how much space you have at your disposal.

Elongating the stairwell’s front end into the attic level usually works as a solution.

Bring Your Attic Ideas to Reality

Ultimately, what you need to know is that not all attics are eligible for conversion as they stand. Your local building codes should always be factored in before starting any work.

At a minimum, if the space in your attic is not large enough for you to stand upright in, it won’t be easily remodeled into a primary bedroom without the addition of one or more dormers.

Transform Your Attic

Despite the limitations of some homes, a creative designer or architect can squeeze enough space for a bedroom and usually a bathroom into most attics. The first step is to have a designer look at the space, share some room ideas, and tell you what might be involved to convert it. It’s helpful to go online and start gathering design ideas so you can get a sense of what you like.

Despite the cost and complication, a new attic suite can be a wonderful addition to your home and positively impact its resale value. The right remodeling firm can bring your design ideas to life. Contact us today to get the conversation started!
