5. Get a Built-in Media Wall

If you’ve got the TV, sound system, speakers and more ready to go but they’re just not working on your wall, consider a built-in cabinet system to beautifully organize all of your electronics for the best experience.

Cost range:

• Moderate-grade materials: For a unit measuring 12 feet wide and 8 feet high, expect to pay between $2,000 and $4,000 for moderate-grade finishes and appointments.
• Higher end: A more upscale unit, with more bells and whistles and a stained wood finish, would probably run you $3,000 to $6,000.
• DIY: Homeowner Christina Katos completed her built-in project for $2,000. (Click on the link below to see more.)

6. Make Your Garage a Storage Powerhouse

See how a professional can help you finally get your garage decluttered and organized.

7. Bring Out Your Home’s Character With Trim

It might sound boring, but some of the small details of your home — like trim — can have a huge effect on the way it looks and feels. See how new trim might be just the embellishment to take your home to a new level.

Moving on up into specialty woods, such as exotic veneers, the price will balloon to $500 to $1,000 per door, and even more for antique and custom doors. Keep in mind that you will have to pay for installation labor and finish materials in all circumstances.

9. Refinish Your Floors

Hardwood floors will start to show wear and tear after about 20 years. But before you rip everything out and replace them with costly new floors, consider refinishing your existing floors first.

Cost range: Most floor refinishers charge by the square foot, but prices vary considerably, depending on your region, your home’s accessibility, the size of the job and the work you want done (including the color of the stain — dark stains take more prep time).

Plan to spend between $2.50 and $5.25 per square foot for sanding, staining and three coats of finish.

10. Add a Murphy Bed

Beds take up a lot of space. If you have a guest room that’s used only a few days out of the year, that means you’re potentially wasting a lot of space. A fold-up bed could help your spare room perform multiple duties.

Cost: This depends on the system, the size, additional shelving and cabinets, who will install it and more. You can get a simple Murphy bed that folds out from what looks like a large cabinet (like the one seen here) for about $2,500; you can get semicustomizable prefab versions starting at $5,000. Bringing in professionals to help integrate a one-of-a-kind custom design will cost more.

11. Switch to a Tankless Water Heater

A properly designed and well-installed tankless water heating system can provide you with constant access to hot water and lower monthly bills.

Cost range: In the U.S. the cost ranges from $2,000 to $4,500 for a completely new system installed; it can vary a lot depending on the amount of work required and the number of individual units.

12. Remodel Your Fireplace

Replacing a fireplace wall is mostly an aesthetic choice, but if yours is a commanding focal point in your room, then it could be worth the time and effort for an overhaul. Plus, an updated fireplace can also increase resale value.

Cost: Drywalling over a brick fireplace could run about $1,500. A 6-foot-wide floor-to-ceiling paint-grade oak or poplar fireplace with a tiled hearth could run around $2,000. Wrapping an entire fireplace wall in stone and adding a custom mantel could run around $9,000.

13. Tear Down a Wall

The goal of most wall-removal projects is to connect rooms and create a more open floor plan. Removing a wall can also bring more light into a space and create better flow. (An exterior wall can also be removed and the area bumped out to increase space.)

Cost:

• To remove a non-load-bearing wall, one story or two, when you’re installing carpet: $2,500 to $3,000
• To remove a single-story load-bearing wall: about $10,000
• To remove a two-story load-bearing wall: $20,000 to $30,000

14. Add a Reclaimed-Wood Wall

A wall paneled in reclaimed wood can add texture and warmth to a space. It also is a way to reuse or repurpose a material left over from a previous renovation or remodel.

Cost: About $4 to $7 per square foot on average

15. Add a Window Seat

This is a great project if you already have a room with a large window and are looking to add more seating, storage, a focal point or all three.

Cost: Simple and small window units can cost $750 to $1,500 plus installation labor. Larger windows or projects with cabinets built into the seat can cost about $2,000 to $5,000.

16. Add a Skylight or Light Tube

This is a great way to bring natural light into dark or windowless rooms, but skylights and light tubes can be part of an integrated design strategy for efficient and passive heat gain.

Cost: Fixed and manually operable skylights with installation can cost a couple of thousand dollars each; automated systems can cost up to $5,000 installed.

17. Prevent Sun Damage Indoors

Sunlight can fade, discolor and damage your fabrics even inside your home. Consider solar window films and more.

Cost: There are a range of costs associated with the various solutions for preventing sun damage.

18. Install Energy-Efficient Windows

According to the U.S. Department of Energy, installing Energy Star–qualified windows can save you up to $465 a year on your electric bills while shrinking your home’s carbon footprint and reducing greenhouse gas emissions.

Cost: Varies based on region and window size, starting at around $300 per window installed and rising from there.

19. Create a Built-in Home Bar

Create a special spot in your home for serving drinks and gathering with family and friends during parties.

Cost: Professionally designed and installed built-in bars might cost about $10,000 to $15,000, but the options and pricing vary.

20. Add a Library Ladder

Make that vertical storage easy to reach with a rolling ladder.

Cost: A library ladder should run in the ballpark of $2,500 to $4,000 installed. However, the price will vary based on the length of the railing, type of ladder, wood species, labor rates, freight and location.

21. Add a Radiant-Heat System

Save energy while increasing your thermal comfort.

Cost range: This is a major upgrade and can cost $25 to $30 per square foot for the entire system design and installation.

22. Install a Dimmer Switch

The light level in a room sets the mood and enhances dining and entertaining. Being able to control the lights can also make a room flexible: If you want to relax, you can turn them down. If you need to work, turn them up.

Cost: $30 for a basic dimmer switch from the hardware store; roughly $1,000 for professional labor and materials to install dimmer switches throughout a home.

23. Add Wallpaper

Wallpaper (or wall coverings, as they are known these days, since many aren’t made from actual paper) is a fun way to transform the look of a room without radically altering the space or investing in new furniture.

Cost:

• Around $35 to $50 for a single roll of low-end paper
• Around $140 for a roll of midrange paper
• $300 or more for a high-end paper

24. Install a Chandelier

Add drama or define a space, such as a dining area, within an open floor plan with a statement lighting fixture.

Cost range: Given that the average electrician charges between $40 and $100 per hour, the job should cost about $200 to $300 for installation parts and labor.

25. Get a Claw-Foot Tub

Apart from the sumptuous look of a vintage tub, using one is recycling at its best, and getting one may not be as challenging as you think.

Cost: Acrylic claw-foot tubs generally range from $1,200 to $2,000. New cast iron claw-foot tubs can cost $1,200 to $5,000, though the average runs about $2,200.
