Altgelt & Associates Outdoor Living Trend Article

Ornamental Grasses and Perennials can bring projects to life! In this article we and two other leading landscape design firms speak about how we use perennials and ornamental grasses in the Front Range Area. We welcome you to review this article, which can be found here, and also encourage you to browse through the latest edition of Colorado Urban Home, which can be found at this link.

The Hardscape Expertise of Altgelt & Associates recognized by Urban Home Magazine


As you can see from the lead image of this story, we love using stone, and other forms of hardscape elements to give emphasis and spacial definition to our gardens and landscapes.

This article features the various creative approaches of four leading firms to the creative use of hardscape elements in four distinctly different fields of design and construction. We have had the privelige of working together with each of the other three firms, whose exemplary work is also shown.

We welcome you to view his article, which appeared in early June, at the following link

Boulder Landscape Design with Massive 24-Ton Boulders

We are currently working on a very large, even spectacular landscape design project. One landscape feature we have already created is a rock feature involving boulders weighing up to 24 tons.

Here is one of the large boulders for this landscape design before installation.

Here is one of the massive boulders for this landscape design before installation.

The installation was a technical challenge. We weren’t even sure if we could get the crane in there, and we had to demolish part of the house before the crane could get through. Fortunately, the house was going to be demolished anyway. The crane had to lift the truck carrying the boulders over a bridge because the truck was too heavy to cross the bridge. We also were not entirely certain how deep we could dig without hitting the water table, but fortunately we had no problem with that.

Below you can see one of the giant boulders being set into concrete. Whenever you see a really massive boulder in a landscape, if it is properly installed, generally about 1/3 to 1/2 of the rock is under ground so that it is securely planted in the earth. In this particular case, we added concrete underground, connecting the rock to the concrete foundation with heavy rebar, grounding the rocks securely even though there is less than 1/3 of the rock underground on the side away from the house. In this way, we are preserving the looming height of the rock which juts dramatically upward 14 feet from the ground on that side.

We handled these 24-ton rocks very gingerly because they are moss rocks and the client really wanted these mossy surfaces to be undamaged by the installation process.

Here is the same boulder being set into concrete re-enforcement.

And in the picture below we can begin to see what the final product will look like from the house. From this side, they present a much more modest six foot tall form, which is something of an optical illusion. As you walk around the rocks, you suddenly find the rocks are 14 feet tall on the other side.

Not only will this provide a main focal point from all aspects of the property, but it will also provide a backdrop accenting different forms of the garden.

Here is the final product which will be seen best from the house.

I always enjoy projects that involve inclusion of massive boulders that incorporate the surrounding landscape and nature with what has been created within.

Private Back Yard Garden Near Chautauqua

Chautauqua Area Garden Design

This landscape design is a tiny little garden near Chautauqua Park in Boulder, Colorado. The Chautauqua area has been a great area for us: we’ve done at least a half dozen garden designs, ranging from really big to very small, in the Chautauqua neighborhood. A big part of the garden is water, and we also put in a nice arbor.

In the foreground above on the left side of the photo, you can see a portion of a very interesting bridge-like construction across the water with three panels, perpendicular to each other, with the big panel going crosswise. It’s kind of a Japanese motif of crossing water. The owners cross the water at least a couple of times every day, when they go from their house to their garage, and when they come home.

And here’s another shot of this special private garden:

Landscape Design for Pulte Project on the Denver Country Club

This landscape design on the Denver Country Club golf course was the first of four Denver projects we did with Bryan Pulte, renowned interior designer. It was a major, major remodel. For starters, we completely tore out the whole existing driveway and part of the related retaining wall, and changed the elevation and grading in major ways.

Before it had been very awkward driving in, as the whole driveway was a straight shot down, creating a very, very poor sense of arrival. Instead, we created a winding, meandering flow that brought you to the arrival plaza. In this photo, you can still feel the curvature of drive behind you, and get a sense of that from looking at the photograph.

Now, instead of the old straight shot driveway that took you immediately to the left side of the house, we created a driveway that curves in such a way that it initially blocks the house from view and then reveals it, giving different glimpses of the house as you enter the property. It’s a long driveway.

We tore out a very large planting bed in front of the front door to create the arrival plaza. In doing so, we sunk the area down by at least 18″ to 2 feet, creating a level plaza. In the photo below, on the right you see both part of the original brick retaining wall and also a new dry stack retaining wall in front. We wanted to keep some of the brick retaining wall for aesthetic reasons, because it reflects the brick used on the house itself. The dry stack wall accomplishes two goals: it is visually attractive and it also covers the foundations of the old brick retaining walls, preventing a frost heaving of those foundations. In some places, we tore out the preexisting retaining walls, building huge freestanding walls to hide the neighbor’s garage doors. This was very tricky in a technical engineering sense.

In the arrival plaza above, what we have here initially are some concentric circles, spiraling out into vortical movement. We utilized hand-smoothed colored concrete made to look like natural stone slabs, alternating with precast concrete split-faced cobble. The cobble looks very much like natural stone, with lots of modulation and color, and it also provides a real grip for tires coming down the steep driveway. So it both looks good and it provides a very important function. As the pavement flattens out, it goes into stamped colored concrete. We were working around a lot of mature existing trees to preserve them, another big technical challenge.

In the back, up on the left side of the photo above, you see the preexisting deck which had no connection to the ground, so we created a staircase coming down with intricate carpentry bringing people gracefully down from this deck which had been isolated. As one comes down the stairs, one walks around a water feature that is the focal point for this small garden space. The upper pool of this water feature finds its source underneath the staircase coming down. As one gets down to the ground, there is sandstone paving, and then one goes back onto what looks at first glance like a bridge in the photo, but it’s simply a lower deck where one can put a table and chairs. From that deck we look down into the lower pool of the water feature. The lower pool is a deep pool with the deck cantilevering over it. We brought in massive rocks, so it’s a very intense rock and water feature. Again, we were working around huge existing trees, and we had to work these 5-6 ton boulders carefully so as not to damage the roots of these trees. We were really pushing the limits, and had to work very carefully.

From the decks, one looks to the north for a view of the Denver Country Club golf course.
