Adding a Turnaround to Your Driveway

You add a driveway turnaround by widening part of the driveway so a vehicle can reverse and pull out forward. The most common ways are a T shaped (hammerhead) turnaround, a paved pad beside the driveway, a circular or horseshoe loop, or a Y shaped spur. Which one works depends on how much space you have, how steep the lot is, what your city allows, and how large your vehicles are. Whichever you choose, the turnaround carries the same loads as the rest of the driveway, so it needs a full-depth base and vehicle-rated pavers.

At Ridgewell Landscape and Design, we build custom driveways across the Denver area, including Broomfield, Parker, and the surrounding communities. Homeowners call us about turnarounds for the same reasons every time: backing onto a busy street feels unsafe, a long driveway makes reversing difficult, or a larger vehicle will not make the turn. This guide covers the main layouts, how much space each needs, the rules to check, and how the work is done.

Why Add a Turnaround

• Safety: Pulling out forward gives you a clear view of traffic, pedestrians, and children
• Convenience: You avoid long, awkward reversing down a narrow or winding driveway
• Larger vehicles: Trucks, vans, trailers, and RVs are much harder to back out than a small car
• Guest parking: A turnaround doubles as extra parking space
• Deliveries and services: Trash, delivery, and service vehicles can turn without driving onto the lawn
• Curb appeal: A well-designed turnaround adds shape and interest to a plain driveway

Turnaround Options at a Glance

The best option is usually the smallest one that lets your largest vehicle turn comfortably.

Layouts Explained

T Shaped Turnaround

A T shaped, or hammerhead, turnaround adds a short leg or two on each side of the driveway, forming a T. You pull forward into one arm, reverse back into the driveway, and drive out facing the street. It is the most space-efficient design and works well on narrow lots where a loop is not possible. The arms are usually placed partway along the driveway or near the garage, depending on where space allows.

Side Pad or Bump-Out

A bump-out is a single paved pad on one side of the driveway, often near the garage. It gives you a place to back into and turn around, and it works as extra parking too. It is the simplest and often the cheapest option, though it requires enough width on one side of the driveway.

Y Shaped Turnaround

A Y shaped design branches the driveway into two angled arms near the house. You can pull into one branch and back out of the other. It uses angles, which makes the movement more natural for some drivers, and it creates a nice shape at the garage, but it takes more room than a simple T.

Circular or Horseshoe Drive

A circular drive lets vehicles loop through without reversing at all, and a horseshoe drive does the same with two entrances from the street. These layouts need plenty of frontage and depth, but they offer the smoothest flow and the strongest arrival feel. We cover design ideas for these in more detail in our guide to best paver driveway ideas.

Motor Court

A motor court is a larger paved area in front of the garage, big enough for parking, turning, and gathering. It suits properties with several vehicles or frequent guests and doubles as a design feature.

How Much Space Do You Need

Dimensions depend on your vehicles, so treat these as general starting points and test with your own car before you build.

A simple way to check is to mark the proposed shape on the ground with spray paint or rope, then try the turn with your longest or widest vehicle. If you have to cut it close, make the pad bigger. Cramped turnarounds get scraped, driven over, and abandoned.

Check the Rules First

A turnaround usually increases the paved area on your lot, and it can change how the driveway meets the street, so check these items before you design.

• Permits: Many cities require a permit for driveway additions or changes
• Paved area limits: Some municipalities cap the percentage of a lot that can be covered with hard surface
• Setbacks: Paving may need to stay a set distance from property lines
• Curb cuts and aprons: Adding a second entrance changes the curb cut and often needs approval
• Easements and utilities: Call 811 to have underground utilities marked, and check for easements
• HOA rules: Associations may regulate width, materials, and color
• Fire access: Some areas require turnarounds or minimum widths for emergency vehicles

A quick call to your city or county planning office before you start can save a lot of trouble.

Planning the Layout

Start With Your Vehicles

Measure the length and width of your largest vehicle and think about trailers or RVs. A turnaround that works for a compact car may fail for a pickup with a trailer.

Think About Where Cars Park

A turnaround should not make everyday parking harder. Place it so the turning space does not block the garage doors or the walkway to the front door.

Consider the Slope

Turnarounds on steep lots need extra planning. A flat pad is much easier to build than a sloped one, and water should always drain away from the house. If the lot needs leveling, a retaining wall can create the flat space. Our retaining wall services cover how we build level areas on sloped properties.

Plan Drainage

A larger paved area sheds more water. Plan where runoff will go so it does not flow toward the house, pool in the new pad, or wash across a neighbor’s yard.

Think About Trees and Utilities

Large tree roots, meters, and buried lines can all affect where a turnaround can go, and removing a mature tree is a big decision.

Choosing the Surface

A turnaround should match or complement the existing driveway so it looks planned, not tacked on.

• Pavers: The best choice for most homes, since they follow curves, match patterns, and can be repaired in sections
• Concrete: Lower cost, but harder to match to an existing surface and prone to cracking
• Asphalt: Cheapest, but difficult to join cleanly to an older driveway and wears faster
• Gravel: Works on rustic properties, though it shifts and needs regular regrading

Pavers must be rated for vehicle traffic. Turnarounds see tight turning and a lot of reversing, which stress the surface more than straight driving, so thin patio pavers are a poor fit. Our post on whether patio pavers can be used for a driveway explains why this is such a common mistake. Aim for pavers at least 3.1 inches thick, and consider 3.5 to 4 inches where heavy vehicles turn.

How a Paver Turnaround Is Built

The process follows the same steps as a full driveway, with extra attention to joining the new area to the old one.

Step 1: Mark the Layout

Stake and paint the outline of the turnaround, and confirm it works with your vehicles before any digging starts. Mark the lines where the new area meets the existing driveway.

Step 2: Excavate

Dig the area to the full depth needed, typically 12 to 16 inches below the finished surface. Cut cleanly along the existing driveway edge, and take care not to undermine it. Remove sod, topsoil, and any soft or organic material.

Step 3: Grade and Compact the Subgrade

Shape the excavated area so the surface will slope gently, about 1 to 2 percent, to move water off the pad. Compact the soil, and on clay or soft soils, lay geotextile fabric to keep the base from mixing with the soil below.

Step 4: Build a Full-Depth Base

Add crushed aggregate in lifts of about 4 inches, compacting each lift thoroughly. Build up to a total of 8 to 12 inches, depending on soil and use. This is the step most often shortened on small additions, and it is the one that matters most, since a thin base leads to dips and ruts where cars turn. Our guide to proper paver base depth explains how soil type and traffic affect the right depth.

Step 5: Install Edge Restraints

Set rigid restraints along all new outside edges, anchored into the base or set in concrete haunching. Turning vehicles push outward on edges, so weak restraints let the pavers spread.

Step 6: Screed the Bedding Sand

Spread about 1 inch of coarse sand over the base and screed it level, matching the height of the existing driveway so the seam is flush.

Step 7: Lay the Pavers

Start along the existing driveway edge and work outward in your chosen pattern, keeping joints at about one eighth inch. Herringbone is the strongest choice for areas where vehicles turn, and matching the existing pattern helps the new section blend in. Cut pavers with a wet saw where the layout meets curves and edges.

Step 8: Compact and Fill the Joints

Run a plate compactor with a protective pad over the surface, sweep polymeric sand into all joints, compact lightly again, and clean off the excess. Mist lightly according to the product instructions.

Step 9: Blend the Seam

Check that the new and old surfaces are flush, fill any gaps, and confirm that water drains across the seam without pooling. If the existing driveway is a different material, a soldier course along the seam gives a clean visual break.

What a Turnaround Costs

Costs depend on size, layout, materials, and site conditions.

These estimates use the typical 20 to 40 dollars per square foot range for professionally installed pavers. Demolition of an existing surface, tree removal, drainage work, permits, retaining walls, and lighting all add to the total. Small additions can cost more per square foot because equipment mobilization and detailed finishing are spread over fewer square feet.

Design Tips

• Match the existing driveway: Use the same paver and pattern so the addition looks original
• Use a contrasting border: A soldier course ties the new and old areas together
• Soften the shape: Rounded corners are easier to drive and look better than sharp ones
• Add planting beds: Low plants along the edges soften the paved area
• Plan lighting: Low-profile lights make turning safer at night and are easiest to install while the base is open
• Keep sight lines clear: Avoid tall plants or walls that block visibility near the street

Common Mistakes to Avoid

• Making it too small: A cramped turnaround does not get used
• Skipping the test: Always try the turn with your largest vehicle before building
• Using a shallow base: Turning vehicles quickly cause rutting on thin bases
• Using patio pavers: Thin units crack under tire loads
• Ignoring drainage: Water pooling on the pad softens the base
• Weak edge restraints: Turning forces spread the pavers outward
• Height mismatch at the seam: A lip between old and new surfaces is a tripping and drainage problem
• Skipping permits: Unapproved paving can lead to fines or forced removal

DIY or Hire a Professional

A turnaround looks like a small project, but it joins new construction to an existing driveway, needs a full-depth base, and has to be laid out accurately so it actually works with your vehicles. Excavating next to an existing edge, matching heights, and planning drainage are areas where experience prevents expensive mistakes. For most homeowners, a professional crew delivers a turnaround that blends in, drains well, and holds up under daily turning.

Getting It Done Right

A good turnaround makes a driveway safer and easier to use, and it works best when it is sized for your real vehicles, built on a deep base, and finished carefully where it meets the existing surface.

Frequently Asked Questions

What is the easiest way to add a turnaround to a driveway?

A side pad or a T shaped turnaround is usually the simplest and least expensive, since each only needs a modest amount of extra paved space.

How big does a driveway turnaround need to be?

It depends on your vehicles, but a T shaped arm is typically about 10 to 12 feet wide and deep, and a side pad is often 10 to 12 feet by 20 to 24 feet. Larger vehicles need more room.

How much does it cost to add a turnaround?

A small paver turnaround commonly costs about 4,000 to 12,000 dollars installed, while a circular drive can cost far more. Pricing depends on size, materials, and site conditions.

Do I need a permit to add a turnaround?

Often yes, especially if it increases paved area, adds a curb cut, or sits near property lines. Check with your city or county and any HOA before you start.

Can I add a turnaround to an existing paver driveway?

Yes. The new area needs its own full-depth base, and it should be joined to the existing driveway at the same height with strong edge restraints.

What is a hammerhead turnaround?

A hammerhead, or T shaped, turnaround adds short legs on each side of the driveway so a vehicle can back into one and pull out forward.

Can I use patio pavers for a turnaround?

No. Turnarounds carry vehicles and see tight turning, so use pavers rated for driveway loads, generally 3.1 inches thick or more.

Is a circular driveway better than a T shaped turnaround?

A circular drive avoids reversing entirely and looks grand, but it needs far more space and costs much more. A T shaped turnaround is more practical on narrow lots.

Ready to Add Your Turnaround
