6 Tips for Rooftop Gardens


Creating a personal outdoor living space on your rooftop, terrace or balcony provides a place to go outdoors for welcome relief from the hustle of high density urban living. Good design can bring precious additional living space to small condos and apartments. These landscapes are different from anywhere else because they are elevated, from a few feet to many stories above the earth. They are also on-structure, which necessitates many unique requirements to ensure you project is buildable, visually appealing and supportive of green plants.
1. Preserve the ViewThe view from a rooftop living space is your most valuable amenity, so all design decisions must preserve and maximize it. Solving practical problems must be done in a way that does not diminish the view. For example, changing a solid wall to a transparent wrought iron railing can greatly enhance the view, and borrow space to make your project seem larger. But if there's an eyesore, replacing a transparent rail with a solid wall may be the perfect solution for retaining the view while screening this undesirable segment.
2. Enhance PrivacyOften balconies are constructed to serve many units, not just yours. To create a private space for relaxation, screening off your neighbors can be paramount. Keep in mind that all solid partitions will influence air movement. This may be a good thing if you have problem wind from that direction, or it can be undesirable in summer when the partition creates stagnant air. This is why partitions are most often made of open material such as lattice or metal grids enhanced with vines. When considering privacy, be aware of your standing privacy needs as well as those when you're sitting down. Discuss this with your designer to find the least imposing solution for privacy while maintaining air movement and view so you don't end up with a potentially claustrophobic space.
3. Mitigate the EnvironmentWhen you invest a lot of money in an outdoor living space, it must be comfortable for you and your plants in as many seasons as possible. In the colder months when you live indoors, the planting and decor should make this space equally as attractive to look at through windows. Your designer's biggest challenge is to put into place elements that mitigate your unique set of climatic challenges with attractive components that work well with your interior style.
Some of the typical problems include west facing units where afternoon heat and full exposure in the summer months can be overwhelming. Here you will need seasonal shade or an umbrella or another creative shade source for you and your plants. Those units located in wind corridors where gales rip through the spaces between large buildings will definitely need protection. Wind screens or selection of plants that tolerate this buffeting may be essential.
4. Furniture: Comfort vs. SizeThe most important commodity in any city is space, where every square inch matters. That's why selecting furniture is so difficult. Big bulky pieces are out, small and well designed is in. Your choice must demand as little square footage as possible without compromising comfort. Strive for a balance of style and versatility. Furniture that blends with that of the adjacent room helps to blend interior and exterior style.
Due to spatial limitations, selecting furniture while designing the space, rather than furnishing as an afterthought, is the best way to preserve every square foot of open space you can. Keep it simple. Otherwise a visually pleasing terrace can feel cluttered, and that makes it far too similar to the rest of the crowded city. In addition, furniture is seasonal. If it must be stored indoors for the winter, be sure it is small and light weight enough to bring in and out easily. Furniture that remains outdoors year around must be sufficiently weatherproof.
5. Accent with PotsWhich is more important, the plant or the pot? The answer is neither. The plant and pot are equally as important, which emphasizes how the right pair turns this practical planting option into living sculpture. Your designer will see these as columns, masses, backgrounds and focal points, and they constitute the most visually dynamic element within the space. In these small urban spaces, your pots are viewed at close range, and the hotter they look the better.
Your designer will have to use great care to obtain the perfectly sized pots to spice up these outdoor spaces, and ensure they are large enough to support the root ball of the designated species. Some will remain outdoors year around, and these must be thick walled and weather proof. If these contain rugged evergreen conifers that are capable of surviving the winter on the terrace, they will become the most important element outside during winter. These may even be used for holiday lighting or become the subject of ambient up-lighting to softly illuminate the space without sacrificing the view.
6. Water for SoundEngineers know that sound travels upward. The din of heavy traffic can be louder a few floors up than it is on street level. This and the general noise of city life can spoil the sense of peaceful separation you are trying to achieve in the living space. This places a high value on the sound of water as a masking device. Due to the unique constraints of on-structure landscapes, this will require both a good designer and an experienced contractor.
Wall fountains make the most space saving style. They stand at the edge of the space against a wall or may even be hung upon the wall, asking for little to no square footage to be devoted to its base. Freestanding fountains are far more demanding. No matter what style of fountain you use, it must above all be variable from a lot of sound to a minimal flow rate during quieter times of the day or night.

Landscape Retaining Wall Basics


A retaining wall is intended to hold back soil when there is a drastic change in elevation. Often retaining walls are used to terrace yards that originally had a steep slope. Additionally, retaining walls can help create usable outdoor space as well as control erosion. Low retaining walls are frequently used as planting beds and can add interest to an otherwise flat yard.
If you are considering hiring someone to build a landscape retaining wall on your property you'll want to have a basic understanding of what goes into proper retaining wall design. This way you'll be sure to get a quality wall that will last for years without problems. An improperly built retaining wall may bulge, crack or lean, creating an unsightly eyesore and a headache for you.
  1. BaseFirst, a retaining wall must be built on a suitable base. Block manufacturers as well as experienced contractors and engineers stress the importance of starting with a good base. The base of a retaining wall should be set below ground level. The taller a wall is, the further below ground level it should be set. Crucial for supporting the rest of the wall, a good base is made of compacted soil and at least a six inch layer of compacted sand and gravel.
  2. BackfillSecond, a retaining wall must have properly compacted backfill. Backfill refers to the dirt behind the wall. In order to provide proper drainage, at least 12 inches of granular backfill (gravel or a similar aggregate) should be installed directly behind the wall. Compacted native soil can be used to backfill the rest of the space behind the wall. If you intend to do landscaping behind the wall, a 6+ inch layer of native soil should also be placed over the gravel fill.
  3. DrainageThird, since most retaining walls are impervious, which means water cannot pass through the wall itself, efficient drainage is crucial. When drainage goes unaddressed hydrostatic pressure will build up behind the wall and cause damage such as bulging or cracking. There are a number of ways to ensure proper drainage of water from behind a retaining wall. First, is to make sure your landscaping contractor backfills at least a foot of space behind the wall with gravel. Second, is having a perforated pipe installed along the inside, or backfilled, bottom of the wall. And third, is to ask if weep holes will be needed to allow water to drain through the wall.
  4. HeightFourth, it's important to know that the height of a retaining wall determines the load it can bear and how much extra reinforcement will be necessary. Typically, residential retaining walls are built between 3 and 4 feet high. This height provides excellent strength without requiring anchors, cantilevers or other additional reinforcements. If your property requires a higher wall you have two options: you can have the wall specially designed by an engineer or you can use a series of 3-4 foot walls to create a terraced effect.
Retaining Wall Design Ideas:
  • Incorporate a fountain or water feature into your retaining wall
  • Integrate an outdoor fireplace into your retaining wall design
  • Install landscape lighting in your retaining wall
  • Include built-in bench seating in your retaining wall
  • Don't forget steps if you plan to access the area above the wall
  • For a finished look, have wall caps installed
