How to Convert an Attic into a Bedroom

Converting your attic into a bedroom can be an excellent solution to add an extra room without the hassle and expense of a full-scale addition. However, the process can be overwhelming if you’re unsure where to start.

This guide aims to simplify the process and provide you with clear steps to transform your attic into a comfortable and useful bedroom. 

Assess the Attic’s Potential

Start by taking a good look at the structural elements. Examine the floor joists, roof trusses, and support beams. Ensure they are in proper condition and robust enough to handle the added weight of a bedroom – the furnishings, occupants, any reinforcements needed. It would be dreadfully inconvenient to get partway through the project only to realise the existing structure simply can’t bear the load.

Regarding the space itself, measure it carefully. Most building codes require a minimum 7-foot ceiling height across at least half the room’s area for it to be deemed a proper bedroom. You would not want to complete the conversion only to find the space does not meet habitation standards.

One final critical consideration – acquire any necessary permits and ensure full compliance with zoning ordinances about increasing the bedroom count of a residence. It would be most unpleasant to exhaust efforts on the

Plan the Attic Bedroom Conversion

Establishing a realistic budget is crucial as converting an attic space is no small financial undertaking. Set a target timeline as well for when you aim to have the work completed.

Then, determine where you’d like the bed positioned as well as the closet and any other furnishings or special features. Feel free to get creative and plan your dream layout.

Start considering material options for the floors, walls, ceilings and trim as you’re designing. Seek out durable, visually appealing and easy-to-install choices. The materials will significantly impact your room’s overall look and feel.

Don’t forget to inspect the current insulation levels and consider upgrading to better insulation. Proper insulation ensures a comfortable temperature and noise reduction for a cosy, peaceful bedroom environment.

Reinforce the Floor (if necessary)

Now, if the existing floor joists in your attic are not up to supporting the added weight of a bedroom, reinforcing the floor becomes an essential step. You can’t compromise on safety so skipping this crucial reinforcement is inadvisable if deemed necessary.

There are a couple of common techniques for reinforcement if needed. One is to “sister” the joists by adding new joists alongside the existing ones which effectively doubles their strength and load-bearing capacity.

Alternatively, installing support beams beneath the joists provides another viable solution that gives the floor system extra fortification and stability.

In this case, it is highly advisable to trust the expertise of professionals. Attempting to cut corners or take shortcuts here could severely compromise the entire project and create potential hazards down the line.

Install Proper Insulation and Ventilation

You have a few different options to consider when it comes to insulation. Fibreglass batts, blown-in insulation and rigid foam boards are among the common choices. Take the time to thoroughly research the pros and cons of each type to determine what will work best for your attic’s specific layout and needs. And be sure to carefully follow all instructions during installation.

Ventilation is equally important. Install vents, fans, or other systems that enable steady air circulation and prevent moisture from becoming trapped inside. 

Plan and execute the insulation and ventilation diligently. Getting this step right will go a long way in creating a cosy, comfortable environment that you can enjoy for years to come.

Add Egress (Window, Skylight, or Staircase)

Most building codes mandate at least one exit route, called an egress in every bedroom space for safety reasons. So for your attic conversion, you need to incorporate a window, skylight, or staircase to meet these requirements.

Consult the specific egress rules that apply to bedrooms in your local area. There are likely to be requirements around minimum window size, maximum window height off the floor, and emergency escape routes that must be adhered to.

If adding a window or skylight is the chosen solution, look into energy-efficient options. These will allow natural light into the space while also providing insulation to help control the room’s temperature.

Alternatively, consider space-saving designs like spiral staircases or alternating tread stairs if a staircase makes more practical sense for your layout. Just ensure any stair solution meets all standards for tread depth, riser height and handrails.

The key is selecting an egress option that satisfies the safety codes while also integrating seamlessly with your overall vision for the new attic bedroom’s design and functionality.

Frame and Install Drywall

Be sure to follow proper techniques and local building codes when framing the walls and ceilings. Doing it right is important for the stability and safety of the new room.

Installing the drywall takes some care, especially in an attic with sloped ceilings and odd angles. Take your time cutting and fitting the drywall pieces properly so there are no unsightly gaps or cracks.

Plan ahead for how to incorporate them into the bedroom design if your attic has unique features like sloped ceilings or dormers. These architectural details can add charm and character with some creativity.

Set up Electrical and Lighting

Look for energy-efficient options like LED bulbs or recessed lights when it comes to lighting. These will properly illuminate the room while keeping your energy costs down.

Don’t forget about natural light too! Strategically placed windows or skylights can brighten up the space during the day while also meeting safety requirements for emergency exits.

The key is working with a qualified electrician to plan and install a lighting and electrical system that is safe, efficient and meets your needs.

But note that this is not a DIY job unless you are a certified electrician yourself. It’s best to hire a licensed pro to handle this step. Find a reputable, licensed electrician you can trust to do all the electrical work

Address HVAC Needs

The most cost-effective option may be extending your home’s existing HVAC system into the attic space. This could mean adding new ductwork or creating a separate zone to control the attic’s climate.

If extending your current system is not possible, you need to install a dedicated HVAC unit just for the new attic bedroom. This is more expensive but it allows for better temperature control in that space.

Add the Finishing Touches

Choose durable, easy-to-install flooring options that are well-suited for an attic bedroom, such as hardwood, laminate, or carpet.

Pick out paint colours and wall coverings that fit your personal style and create an inviting ambiance. Select cosy and functional furniture that meets your needs. Add those personal touches through art, photos, plush textiles and more to make it feel like a true home away from home.

Don’t be afraid to get creative and express yourself through colour and design. Take your time with these final touches – the more thought and care you put in, the more you’ll enjoy your new haven.


Converting your attic into a beautiful new bedroom is tremendously rewarding when done right.
