Hammerhead Stoneworks offers a stone fire pit design solution for small patio spaces. This past spring I built what I call an Invisible Fire Pit. This is a design solution for a small patio area. A typical stone fire pit can take up a great deal of space. In a small area, this can be problematic, as it limits the amount of outdoor furniture one can use, or make it hard to entertain in the space at times when a fire isn’t desired. The Invisible Fire Pit is built down into the ground, but has a stone cover, so that when not in use, it really isn’t noticed. You can walk right over it with no indication that the space beneath your feet is hollow. Of course, this raises the issue of how to access the fire pit. I had my blacksmith friend Lynda Metcalfe make wrought iron handles. These are drilled through the stone and rest in a small groove I cut into the top of the stone. With the handles recessed in this way, there’s no trip hazard. The stone is still heavy, so it’s best to lift it with a friend! Last weekend the client had us over and my boys roasted marshmallows over the fire with his daughter. It was a great fun and the fire pit will get plenty of use in the coming months, as the nights cool off so perfectly.
This set of stone steps replaced a worn bank that was prone to washing out in a good rain and becoming slippery and messy. And while not a formal entrance to the house, this is the main access for the family. When I build stone steps, I make sure that the rise and run is consistent throughout the staircase.
Hooper’s Creek is quarried in Fletcher, North Carolina- the nearest source of workable building stone to Asheville. It is a type of granitic gneiss, a metamorphic stone that is extremely hard and dense. It has a great texture and it sounds like glass when you hit it with a hammer.
These images show a patio made almost exclusively of Hooper’s Creek. And some pebbles of course. The grain of Hooper’s Creek gives it the sharper angles and straighter lines than the sandstones often used for flagging.
I just completed a project in Saluda, North Carolina today. The home was built some time in the 70’s and the existing concrete steps were broken down and needed replacing. New stone walkways were in order as well. I built most of the new walkways over the existing sidewalks, dry laid on a pea gravel bed. The image above shows the new steps; the image below shows the area before we got started. Note the awkward spacing of the original steps; it was hard to hit your stride walking them.
The brick pathways wrap around the house, from the formal front entrance (shown above) to the opposite side of the house, which receives most of the traffic.
This short stretch of concrete was poured recently and broke up quite easily under the jackhammer assault. Most of the sidewalks were poured when the house was built and were a pain to break up. They crumbled into dust and would absorb the jackhammer’s impact. It didn’t help that they were up to nine inches thick.
Blue Spiral patio- an art project in Gainesville, Florida
In April I got a phone call from the Art in Public Places Trust (APPT) in Gainesville, Florida announcing that I had been selected to complete a public art project. I am going to build a mosaic stone floor in a courtyard adjacent to a new building on the campus of the Gainesville Regional Utilities (GRU). In May I visited the site and met the APPT board and toured the campus/construction site. Back home, I set about drawing.
During my visit to Gainesville, I found myself drawn to the local stone. The area limestone is dense with the fossilized remains of ancient sea creatures. I took pictures of fossil-rich boulders and sketched from them, looking for forms and relationships that might translate into a patio surface. My source photographs and fossil books opened up interesting explorations, but always led me to the same place. By the very nature of seashells, their forms are instantly recognizable and iconic. I strived to sidestep that iconic nature, for fear of creating a floor that looked like wallpaper. The APPT encouraged me to explore natural shapes, but avoid graphic depiction. The seashells were too graphic, too decorative, too obvious.
The design I proposed for the Gainesville public art feature contains a central spiral element, drawn from my fossil sketches. I have shattered the form with other shapes, lines that intersect it and obscure it. It is a form emerging from a background. Like the process of discovering a seashell embedded in an ancient rock, so the nautilus shape emerges to the eye slowly. The intersecting lines suggest water steadily wearing away the matrix surrounding the fossil, stone slowly giving up its secrets. I hope to capture that same magic of discovery for people first venturing upon my mosaic.
The Biltmore Forest Walkway project entails replacing a 40 year old walkway leading to the front entrance of a house in Biltmore Forest. The existing walkway was set in sand on soft soils and had settled, shifted and recently been overrun (underun?) by moles. After removing the old stone- to be reused- I dug out the sand and soft soil. I replaced the substrate with road bond and compacted it with a jumping jack tamper.
I’m using pea gravel as my setting bed. The compacted road bond and the pea gravel in combination create a very unfriendly environment for moles. It’s also less attractive for their favored foods, like worms. This is what the area looked like after the prep work was done, before I started setting stone.
The original material is no longer quarried, but a similar stone, a granitic gneiss called Hooper’s Creek, is a good match. The key to mixing different types of stone is to make the mix consistent throughout. It’s obvious when you introduce a new type of stone halfway through a project. But if you have all the varieties in play from the first stone, it usually works out fine.
My Friday goal was to finish the matrix, what I call the edges and the big stones that connect the sides, leaving only the fill-ins and details for Monday.
Friday Quitting Time
Except for that one area at the very end, the matrix is done. Monday is all about filling the gaps.
The new class schedule for the North Carolina Arboretum was recently announced. I am leading three stonework classes this spring. DIY Flagstone Paths & Patios will be offered twice, on Saturday April 10th and on Friday April 16th. In the morning session, we discuss the basics of drystone flagging: necessary site prep, the principles of good structure and varying joinery styles. In the afternoon we go outside to the stone classroom and practice the essential skills: moving stone safely, shaping individual pieces and leveling the patio.
I am offering a brand new class this spring, called Stonework Special Projects: Making a Bench on Saturday May 15th. In the morning we will discuss the design and structural issues of building a stone bench. In the afternoon we will build a freestanding bench ourselves. Topics of note including cutting stone with feathers and wedges and how to move large stones safely.
I built this walkway last fall using Pennsylvania bluestone. In this image you can see both the true and full-color bluestone. The path is 42″ across and laid dry. There’s a small set of steps in the middle; the very straight line at the bottom of the image is the back edge of the top step. The steps are Tennessee sandstone, but they fit the color palette well. The path is drystone, with no mortar or concrete at all. It leads to the main entrance of a private residence.
