When people think of remodeling, kitchens and bathrooms usually steal the spotlight. But what if we told you some of the most valuable and cost-effective remodels come from the spaces you’ve forgotten about?

Many Long Island homes — especially older capes, colonials, and ranches — have hidden corners and underutilized areas that, with the right remodeling approach, can become standout features of your home. Whether it’s converting an attic into a guest suite, turning the mudroom into a sleek laundry zone, or transforming an unused garage into a home office, these overlooked spaces are full of potential.

We’ll uncover the best unused spaces to remodel in Long Island homes, share expert design tips, and show you how to unlock hidden value—without needing full-scale renovation.

Why Remodeling Unused Spaces Is a Smart Move

Remodeling unused spaces is one of the most economical ways to enhance your home. Instead of adding on or expanding the footprint (which can quickly get expensive), you’re simply optimizing what’s already there. Spaces like attics, basements, under-stair areas, or garages can often be transformed with less labor, fewer materials, and faster timelines than full additions.

1.1 A Cost-Effective Way to Upgrade

Remodeling unused spaces is one of the most economical ways to enhance your home. Instead of adding on or expanding the footprint (which can quickly get expensive), you’re simply optimizing what’s already there. Spaces like attics, basements, under-stair areas, or garages can often be transformed with less labor, fewer materials, and faster timelines than full additions.

1.2 Add Livable Square Footage—Without Expanding Your Home

In the dense areas of Long Island where zoning restrictions or property lines make building out difficult, reimagining the interior is the perfect solution. By turning a forgotten corner or unused room into a functional space, you’re adding livable square footage without needing a permit for expansion or new foundation work.

1.3 Increase Home Value and Day-to-Day Functionality

Today’s buyers—and families—crave smart layouts that work for modern life. A finished attic, a mudroom that tames the chaos of everyday clutter, or a sleek under-stair storage system all make a home feel more thoughtfully designed. These upgrades not only boost resale value but also make your home more enjoyable to live in right now.

2. Unique Layouts of Long Island Homes: Hidden Potential

Long Island homes—especially classic styles like Cape Cods, ranches, and split-levels—often come with quirky floorplans and architectural oddities that leave certain areas underutilized. Whether it’s a narrow nook under the stairs, a low-ceiling attic, or an awkward basement corner, these older layouts hold untapped potential just waiting to be transformed. Many of these homes were built with utility in mind, not modern lifestyles—leaving behind bonus spaces that today’s homeowners can reimagine as mudrooms, home offices, cozy reading alcoves, or extra storage. Renovating these hidden gems is not only a smart way to improve functionality but also a chance to add value without changing the home’s footprint.

3. Top 4 Unused Spaces You Can Remodel

3.1 Attics: The Overlooked Goldmine Above Your Ceiling


Attics are one of the most underutilized areas in Long Island homes, especially in older capes, colonials, and split-levels. With the right renovation, that dusty storage zone can be transformed into a fully functional—and beautiful—living space.

Why Remodel Your Attic?

  • Instant Livable Space: No additions or new foundation needed—just use the square footage you already own.
  • Ideal for Privacy: Because they’re tucked away, attics make perfect guest rooms, offices, or retreats.
  • Boosts Home Value: An attic conversion adds heated square footage, which directly increases market value.

Top Attic Conversion Ideas:

  • Home Office or Studio: Quiet, elevated space perfect for focus and creativity.
  • Guest Suite or Teen Bedroom: Add a skylight and custom closets for a cozy yet functional vibe.
  • Reading Nook or Lounge: Sloped ceilings create a snug atmosphere ideal for relaxation.
  • Hobby Room or Music Studio: A great soundproofing opportunity.

Design Tips for Attic Renovations:

  • Maximize Vertical Space: Use knee-wall storage, built-in shelving, and floating desks.
  • Natural Light: Skylights and dormer windows can completely transform the feel of the room.
  • Ventilation & Insulation: Most attics need upgraded airflow and temperature control—don’t skip this step.
  • Floor Support: Ensure the floor structure can handle living-space weight (LPS Direct can handle the structural assessment).

Estimated Cost Range:

💰 $25,000 – $75,000+, depending on size, stairs, HVAC, windows, and structural changes.building permit is usually required for attic remodels that add HVAC, windows, plumbing, or convert it to a sleeping space.

Pro Tip from LPS Direct:

Use light colors and minimal furniture to make low-ceiling attic spaces feel airy. A good attic renovation isn’t about square footage, it’s about smart design.

3.2 Mudrooms: The Most Underrated Room in Your Home


A mudroom may not be the flashiest space in your house—but for Long Island families dealing with all four seasons, it can become the most functional and appreciated room in your home. With the right remodel, it transforms from a pass-through to a hardworking entry point that organizes your life.

Why Remodel Your Mudroom?

  • Boosts Daily Efficiency: A well-designed mudroom helps keep shoes, coats, school bags, and pet gear in one place.
  • Protects Your Home: Prevents mud, snow, and salt from being tracked through the house.
  • Adds Resale Appeal: Buyers with families love organized entry spaces that show thoughtfulness in the home layout.

Smart Mudroom Ideas for Long Island Homes:

  • Custom Built-In Lockers: Create a personalized cubby system with hooks, shelves, and baskets.
  • Mudroom-Laundry Combos: Maximize utility by combining the mudroom with a washer/dryer zone.
  • Pet-Wash Stations: A tiled step-in wash area is a hit for dog owners—especially after beach trips or muddy backyard runs.
  • Shoe & Boot Drawers: Pull-out storage that keeps wet footwear off your floors.

Design Features to Consider:

  • Durable Flooring: Go with non-slip tiles, luxury vinyl, or sealed concrete to handle moisture and dirt.
  • Bench Seating: Include lift-up storage under a bench for gloves, hats, and bags.
  • Hooks & Cabinets: Mix open and closed storage to keep it clean yet accessible.
  • Lighting: Add motion sensor lighting for hands-free convenience.

Estimated Cost Range:

💰 $8,000 – $25,000, depending on size, built-ins, plumbing (for laundry/pet station), and finishes.

Pro Tip from LPS Direct:

Always design your mudroom for real life. If your kids drop their bags on the floor no matter what, plan for that, build a cubby or drop zone where it makes sense naturally.

3.3 Garage Conversions: From Car Storage to Livable Space

For many Long Island homeowners, the garage is nothing more than a catch-all for storage bins, holiday decorations, or that treadmill you swore you’d use. But with smart design and the right permits, your garage can become one of the most versatile—and valuable—spaces in your home.

Why Convert a Garage?

  • Extra Square Footage: Add livable space without expanding your home’s footprint.
  • Flexibility: Use it as a home office, guest suite, gym, art studio, or even a legal accessory dwelling unit (ADU).
  • Increased Property Value: According to Remodeling Magazine, garage conversions can recoup 60–80% of the investment.

Popular Garage Conversion Ideas on Long Island:

  • Private Home Office: Especially valuable post-2020, with more remote and hybrid workers.
  • Fitness Room or Home Gym: No commute, no excuses.
  • Guest Suite or Rental Unit: Ideal for multigenerational living or short-term rental income.
  • Playroom or Teen Hangout: Give kids their own space (and yourself some peace).

Design Considerations:

  • Insulation & HVAC: Most garages are not climate-controlled, so add insulation and a mini-split system.
  • Flooring: Durable options like vinyl plank or polished concrete work well.
  • Natural Light: Add windows or replace the garage door with French doors or large sliders.
  • Soundproofing: Especially important if converting into a studio or office.

Estimated Cost Range:

💰 $20,000 – $50,000, depending on size, finishes, plumbing, and electrical upgrades.

Pro Tip from LPS Direct:

Before starting, declutter and remove everything from your garage. This will help you visualize the space’s full potential and avoid last-minute storage issues. LPS can help with a phased plan, including design, permitting, and execution.

3.4 Under-Stair Storage: Small Space, Big Potential

That awkward space under your staircase doesn’t have to be a dead zone. With a little creativity and the right craftsmanship, you can turn it into a highly functional feature that adds storage, style, and even resale value.

Why Remodel Under the Stairs?

  • Optimizes Dead Space: Perfect for Long Island homes where every square foot matters.
  • Customizable: Tailored to fit your lifestyle—whether that means shoes, wine, books, or even a pet nook.
  • Visually Striking: A well-designed under-stair area becomes a design statement, not an afterthought.

Creative Under-Stair Ideas LPS Can Build:

  • Pull-Out Drawers or Cabinets: Maximize functionality without visual clutter.
  • Built-In Bookshelves or Display Niche: Turn it into a mini-library or gallery wall.
  • Hidden Closet or Mudroom Overflow: Store coats, umbrellas, and bags discreetly.
  • Mini Home Office or Homework Station: Tuck a desk, outlet, and lighting under the stairs for a stylish workspace.
  • Pet Retreat: Custom dog house or litter zone with washable surfaces and ventilation.
  • Wine Cellar: Install wine cubbies or a glass-enclosed wine display for a wow factor.

Design & Construction Considerations:

  • Staircase Style & Structure: Not all stairs allow for deep built-ins—LPS can assess framing and load-bearing elements.
  • Ventilation: Especially important for enclosed cabinetry or pet nooks.
  • Lighting: Recessed lighting, LED strips, or motion sensors add polish and convenience.
  • Material Selection: Choose durable, easy-to-clean finishes, especially if it’s near an entryway or kitchen.

Estimated Cost Range:

💰 $3,500 – $12,000, depending on size, complexity, and custom carpentry.

Pro Tip from LPS Direct:

Think of this as the “junk drawer” upgrade—but in a good way. If you’re always looking for a spot to put daily-use items, a custom under-stair solution will save time and keep your home cleaner.

3.5  Basements: Unlocking the Hidden Value Below Your Feet

Basements are often the most overlooked square footage in Long Island homes, but they hold immense potential when thoughtfully remodeled. From dark storage zones to damp, unfinished spaces, basements may not scream “dream home” at first glance—but with the right vision, they can become one of the most valuable and versatile areas in your house.

Why Renovate Your Basement?
Maximize Livable Space: Transform unused square footage into a guest suite, rec room, gym, or home office.
Increase Property Value: Finished basements boost your home’s marketability and resale price.
Adapt to Lifestyle Needs: Growing families, multigenerational living, or remote work? The basement can flex with your needs.

Smart Basement Ideas for Long Island Homes:
Media or Game Room: Perfect for movie nights, hosting friends, or letting teens hang out in their own space.
In-Law Suite: Create a private area with a small kitchenette and bathroom for extended family or guests.
Home Gym or Studio: Soundproofed walls and rubber flooring can turn your basement into a fitness haven or creative workspace.
Storage Built-Ins: Incorporate custom shelving, hidden closets, or under-stair drawers to keep things tidy.

Design Features to Consider:
Moisture Control: Use waterproofing systems, dehumidifiers, and mold-resistant materials to keep the space dry.
Ceiling Height Solutions: Exposed beams, low-profile lighting, and smart layout choices make low ceilings feel taller.
Warm Flooring Options: Choose engineered wood, vinyl plank, or cozy carpeting with insulation to make the basement feel welcoming.
Multiple Zones: Divide the space into functional areas (e.g., lounge, play, laundry) with creative room dividers or built-in shelving.

Estimated Cost Range:
💰 $25,000 – $75,000+, depending on square footage, plumbing needs, insulation, and finishes.

Pro Tip from LPS Direct:
Before starting a basement remodel, get a professional inspection to check for moisture issues, ceiling height compliance, and structural integrity. Fixing small problems up front can save you big headaches—and help you create a basement that truly adds to your lifestyle and home value. Read more about basement finishing in Farmingdale, NY.

4. Cost vs. ROI: Are These Remodels Worth It?

Why These Upgrades Make Sense on Long Island

  • High Cost Per Square Foot: Livable space is at a premium in Nassau and Suffolk counties—remodeling unused space is more cost-effective than building an addition.
  • Older Home Stock: Many Long Island homes (especially Cape Cods and splits) were built mid-century and lack modern layouts. Thoughtful upgrades modernize without major reconstruction.
  • Lifestyle Shifts: With more people working from home or needing multigenerational spaces, flex areas like finished basements and attic offices are in high demand.
  • Buyer Psychology: Homes that show well-organized storage, drop zones (mudrooms), and smart use of “dead space” stand out in listings and open houses.

“Buyers on Long Island are always looking for that extra edge—especially families. A finished basement or well-designed mudroom often makes the difference between an offer or a pass. The ROI is not just in dollars, but in faster sales and stronger demand.” — Local Realtor, Suffolk County

6. Space-Saving Design Tips from the LPS Team

Whether you’re working with a tight hallway nook, a compact attic, or a small mudroom, thoughtful design can make all the difference. These are our go-to space-maximizing tricks that help Long Island homeowners get more from every square foot.

1. Built-In Everything

  • Wall-to-wall storage units, window seats with storage, and custom bookshelves create structure without taking up extra floor space.
  • In kitchens or mudrooms, built-ins help eliminate clutter and maximize utility.

2. Dual-Purpose Furniture

  • Use murphy beds, fold-out desks, or ottomans with hidden storage in small rooms.
  • Add a bench with cubbies in your mudroom, or a dining banquette with lift-up storage.

3. Vertical Space is Your Friend

  • Don’t forget the walls! Install shelving above doors, hooks for hanging baskets, or even ladder-accessed loft spaces in converted attics or garages.

4. Sliding Doors Instead of Swinging

  • Pocket doors or barn-style sliders save valuable space—perfect for closets, pantries, or bathrooms where swing clearance is tight.

5. Mirrors & Light Colors

  • Reflective surfaces visually expand the room.
  • Light paint, glass doors, and natural light sources all help small spaces feel bigger.

6. Integrated Storage Solutions

  • Think of toe-kick drawers in kitchens, stairs with built-in drawers, or recessed medicine cabinets.

7. Open Shelving (But Not Too Much!)

  • Great for making spaces feel airy—just don’t go overboard or it can look cluttered. Use a mix of open and closed storage.

Pro Tip from LPS Direct:

Design isn’t just about beauty—it’s about behavior. Watch how you naturally use your space and build around that. Smart design makes life easier.

7. Improving Energy Efficiency During Small Remodels

Improving Energy Efficiency During Small Remodels
One of the smartest ways to increase home value—and reduce utility bills—is to incorporate energy-efficient upgrades during your remodeling projects. Whether you’re finishing a basement, converting an attic, or updating a mudroom, small remodels present the perfect opportunity to boost your home’s efficiency without launching a full-scale renovation.

Simple Efficiency Upgrades That Make a Big Impact:
Add Insulation: If you’re already opening walls or ceilings in a basement or attic, add high-quality insulation to help regulate temperature year-round. This is especially valuable in older Long Island homes where insulation may be outdated or minimal.
Modern HVAC or Mini-Split Systems: Spaces like finished basements or attic rooms often lack ductwork. Mini-split systems are an energy-efficient, cost-effective solution to control temperature in these zones without overworking your main HVAC.
Energy-Efficient Windows: Replacing drafty old basement or attic windows with Energy Star-rated models helps maintain consistent temperatures and can qualify for rebates.
LED Lighting: Upgrading to LED lighting not only reduces energy use but also provides better illumination—key in areas like basements that tend to be dim.

Long Island Tip:
PSEG Long Island often offers rebates or incentives for energy-efficient home upgrades like insulation, HVAC, and lighting. Taking advantage of these programs can help offset upfront costs and improve your remodel’s ROI.

Pro Tip from LPS Direct:
Plan your energy upgrades in tandem with your remodel. For example, if you’re finishing a basement, insulate the walls and floors before drywall goes up. The goal is to improve comfort and efficiency—without adding extra steps or costs later.
