Big Stone Patio

The patio is what we call big stone paving, and it is one of Hammerhead’s signature styles. It is made of sandstone slabs (also used here) about two inches thick and also connects to a pair of boulders found on the property.

As a preventive measure to protect the look of the patio from grease drippings, we ensured that the grill is set in a small gravel area next to the patio.

The shape of the patio is very free-flowing and truly complements the both the modern design and color scheme of the house.

Sandstone Path with Landings

Sandstone Path with Landings

This path was designed and installed for the entryway of a house of modern design in Alexander, North Carolina. It is 4 feet wide and is comprised of boulders found and selected around the site as well as Tennessee sandstone (also used here and here).

In addition to helping to maintain a comfortable walking rhythm, the steps and landings are spaced to run with the slope. This was essential in order to avoid excessive excavation and/or build up.

The Mountain Waterfall Mosaic

The Mountain Waterfall Mosaic is located at First Baptist Church of Asheville, and it was the last part of the Memorial Garden that we completed there. The waterfall was a collaborative effort between Hammerhead and the crew at Medallion Pools led by Mark Dorsey. While Mark and crew took charge of the waterwork elements of the waterfall, Hammerhead was charged with designing and installing the stone.

Details About the Mountain Waterfall Mosaic

The waterfall is located at the end of the stream path. In fact, the bluestone that runs throughout the stream path represents the flowing water and widens as it reaches the pool. The floor of the pool is completely done in the bluestone as well. The sky in the waterfall mosaic is also bluestone, and I like the implied metaphor here. These elements were key components of the design created by Steve Wyda and Ryan Blau of Vision Design Collaborative, the landscape architects who designed the Memorial Garden.

The spillway is made of mountain stone, while the sun and sunset clouds are made of Tennessee sandstone. The Tennessee sandstone is used throughout the entire project at First Baptist Church of Asheville, including in the stream path, the labyrinth itself, and several of the benches. The mountains are made of a native stone that is sometimes called Emerald Gray. We were able to source it from Marion, NC, a town about an hour east of Asheville.

Our Thoughts About this Project

The waterfall was a very challenging build. It wasn’t one project but rather ten small projects combined, each with its own specific components. And when it was done and the water was flowing for the first time, it immediately became my favorite. The sound of the water washed away the months of stress of getting the whole garden finished.

At Hammerhead, it’s the challenges of the project that get us excited. We will take on almost any project, but we do have a couple of rules: no veneer and no water features. Of course, we broke both of these rules for the waterfall. The mosaic background – the mountains and the sunset – is a cut stone approach to veneer. It’s 4 inches thick, basically the depth of the brick, and is affixed to a block wall coated in shotcrete. I am proud to say, it doesn’t look like any lick’em-stick’em I’ve ever seen.

I try to avoid the naturalistic water features that are so commonplace now. Making mountain streams is Mother Nature’s domain, not mine. But this waterfall had just the right balance of creative freedom in the design, execution, and technical challenges to keep us all engaged and excited about the outcome. It’s my favorite project – for now…

Garden Stonework in Mardi’s Yard

Over the last several years Hammerhead Stoneworks has worked closely with garden designer Mardi Letson, owner of Gardens by Mardi. The images below are from garden stonework projects we’ve done in her own yard. Mardi has a wonderful sense of design and can integrate plants into stonework wonderfully. She’s very talented and very easy to work with. She is especially good at working with small spaces as is demonstrated in her own yard. Her yard is not huge by any means, but it has so many little rooms and small special places to hang out.

Dealing With Drainage On A Stone Patio

One way to address drainage concerns in a stone patio

One way to address drainage concerns in a stone patio


Usually it is fairly easy to ensure a stone patio drains properly. Pitch it away from the house- making sure that sub grade drains away from the house as well, and the job is done. But sometimes the patio area is captured by garden beds, sloping yards and other land forms that make it hard to get water away from the home. I have used this drain design a handful of times to provide water with a path away from the patio.
The cobblestone/trench drainage system works off water’s tendency to follow a surface. The cobbles provide rainwater runoff with numerous opportunities to flow down into the pipe below and out into the yard.
A couple of things that help to keep the system working properly.
• Make sure you have a reasonable amount of slope in the pipe. Two percent works well.
• Keep the drainage material (gravel and pipe) free of debris and soil. Water needs to percolate through. That’s why you wrap it in filter fabric and put a sock on the pipe. Use a good grade of filter fabric. The plasticy stuff big box hardware stores sell for under mulch beds is not up to the job.
• Use white PVC pipe, not the thin-wall, cheapo, black corrugated pipe contractors favor. It’s crap.
• Put the holes in the perforated pipe down. The trench fills with water from the bottom up. As soon as it reaches the height of the holes, it starts to drain into the pipe and flow out.
• Keep the daylight exit clear.

Here’s a cobblestone system installed. Done right, it can provide an intriguing visual design element to a patio. This particular system begins and ends with grinding wheels. In this case the patio and cobble stones are sandstone from Tennessee. Cobbles are not necessary, though they do provide increased opportunities for the water to perc into the drain system.

I have installed similar systems at the edge of patios where grass or mulch beds have created puddles or soggy soil. The one pictured is in the center of a patio that is stuck between the house and a steady rising slope.

On Making Labyrinths

Labyrinth paths loop back at returns called labryses.

Labyrinth paths loop back at returns called labryses.

The places where the labyrinth path returns, turning back on itself, are called labryses. This name reflects their shape, which some see as similar to an ceremonial ax. What’s interesting about cutting them is that those shapes –which we creatively called D’s– are all the same. Each of the eleven paths has its own radius, but they all meet the labrys stones in the same way. We only needed one template to cut all of the D shapes.

Stone Path on a Gradual Grade

In the mountains of western North Carolina, where Hammerhead Stoneworks is located, we often deal with awkward slopes. Gradual grades, like the one pictured here, are common. The best solution usually involves striking a balance of steps and landings. This walkway features several small stacks of slab steps with flagstone landings spaced throughout. It’s important to take the rhythm of walking into account. The rise and run of steps are an agreement between the builder and everyone who uses their steps. It should be predictable and within a ratio that we are familiar with. Stuttering steps- those awkward ones that are too short or too close together or weirdly spaced- drive my crazy. (A common thing here is the two inch step at the top of a run of stairs. WHY?!)
Of course, there are other variables as well. You want to steps to fall naturally into place along the slope. If your steps are too far ahead, then you have to do a lot building up with retaining walls to support the steps. Likewise, if you get too far into the slope, there’s a lot of digging needed and you may have to install some sort of edging to keep the soil and mulch off the path. Sometimes this can’t be avoided, but often, by taking the time to pay attention to those details in the design phase, you can have a stone path that has a natural rhythm, is safe and easy to walk and is strong and durable. Like this one in the pictures!

Sunflower Mosaic for Frankie

This mosaic patio was created for my friend Carmen. She needed something to cover the muddy space just outside the doggy door that leads off her porch. Frankie, the puppy in the picture, is an enthusiastic digger and was tracking in altogether too much mud. I had wanted to try a sunflower design in stone and this seemed like a good opportunity.

The seeds are Mexican beach pebbles anchored in concrete. I cast that piece in an retired plastic flower pot. The rest of the stone is laid dry on a bed of crushed stone and sand. The background is Pennsylvania stone and the flower petals are sandstone from Tennessee. I might simplify the design if I were to revisit it. There’s a slight “S” curve on the petals that required more time for cutting and shaping than a straighter line might have, though if it were bigger, that curve would be easier to cut.

North Asheville Stone Patio and Steps

A drystone retaining wall supports a set of carefully stacked steps. This is an overview of a recent Hammerhead Stoneworks project in North Asheville.

This is a recent Hammerhead project, a patio and wall combination to create a exterior space at a home in North Asheville. We used sandstone from Tennessee, one of our favorite stones for tight walls and flat floors.

A favorite detail of this project is the set of steps that emerge from the face of the wall. It’s all dry laid- no concrete or mortar. The design offsets two walls, providing support for the steps. This creates the effect of a single wall that is pulled apart to reveal the steps. I love the look and like how sturdy they are.

Black Mountain Patio

We just finished transforming this Black Mountain backyard from a ragged old deck with drainage issues into a dynamic living space with a fire table. Over the course of the last year we have been using larger and larger slabs of flagstone, but keeping our very tight tolerances for the joints. The results are more like a floor in terms of level and walking comfort than the typical concept of a patio, which is often as much filler as stone. All of the work here is drystone, except for the fire table, which has some refractory mortar in the fire brick for stability. I’ll post about that when I have some good images of it in use.
