Garage/Basement Conversions Are Popular in Brentwood and Middle Tennessee: Is It Right for You?

August 20, 2025


 

Brentwood and Middle TN has seen a surge in creative garage conversions, from cozy guest suites tucked off the kitchen to your dream home gym or the perfect work-from-home office. Whether you’re eyeing extra living space or modern productivity zones, these transformations offer flexibility and added value. 

Let’s walk through the rising trends for garage/basement conversions in Brentwood, TN and whether this is the right move for you with RSU Contractors.

Guest Suites, Gyms, Home Offices & Media or Game Rooms 

With lifestyle shifts like remote work, multigenerational living, or wellness focus, homeowners are tailoring garages to suit new priorities. Instead of building expensive additions, converting existing garages lets families create:

  • Guest suites with private bathroom access
  • Home gyms for seamless workouts
  • Home offices in a separate, quiet zone
  • Media or game room

These improvements let you leverage existing structure, making conversions faster and typically more cost-effective than new builds. 

Choosing Between Guest Suite, Gym, Office, or Media Room

Thinking about adding a room but want to be efficient with space? Let’s talk options:

  • Guest Suite: Ideal if you host overnight family or want an Airbnb-style rental, this adds privacy and often includes a bathroom or kitchenette.
  • Home Gym: Perfect for fitness lovers, this choice offers easy to install rubber flooring, ventilation, and mirrors turn concrete into motivation central.
  • Home Office: Remote work is here to stay. A converted garage offers isolation and productivity without giving up the main living space.
  • Media or Game Room: These spaces are great for entertaining or as gathering spots for the family

Technical Considerations & Value

Costs for these conversions can vary greatly depending upon the scope of work and finishes. These projects may also require:

  • Proper insulation and finishing to meet code
  • Floor leveling or raising to match home
  • HVAC extensions or dedicated systems
  • Electrical upgrades, lighting, outlets
  • Possibly bathroom plumbing or windows for natural light and egress 

The payoff? You gain functional space and potentially a return on investment, worth more than the cost since it enhances your home without expanding it.

Budget Planning & Timeline Insights

A typical garage-to-living-space transformation may wrap up a few weeks when utilizing professionals, versus months for DIY or major new construction. Here’s a planning tip:

  • Set a realistic budget (low, mid, high)
  • Decide the primary function (suite, gym, office)
  • Consult a contractor early for accurate estimates and timeline

These steps can help avoid surprises and keep your project streamlined.
