Landscape Design Project

8 lessons

Introduction

The aim of this lesson is to take your 3D perspective drawings of your landscape design and turn them into 3D SketchUp models. By the end of this lesson, you should have developed a real-world proportionate SketchUp model, completing research into ergonomics to truly explore the functionality and aesthetics of your landscape design.

You Need

  • Device
  • Internet
  • Notebook or digital portfolio for collating ergonomics research
  • Paper
  • Pencil/pen
  • Ruler
  • SketchUp 

Think About

  • The ergonomic proportions of your landscape design overall (aesthetic considerations), as well as specific functional elements within it, such as stairs, ramps, seats, benches, walkthrough structures, (functional considerations) etc.
  • Doing research into ergonomics, as well as taking measurements in existing spaces, will help you figure out the functionality and aesthetics of your design in the real world, before you build it in SketchUp

Lesson Content

  1. At this point, you should have carried out the detailed analysis of a few different divergent designs of your landscape space, exploring what will and won’t work both functionally and aesthetically to meet your brief.

    After completing good perspective drawings of your design/s, you may want to explore their opportunities in a digital format - CAD design.

    You may be really keen to jump into 3D softwares such as SketchUp, or you may be a bit nervous due to the reality that you now need to show not only the aesthetics of your design, but the functionality of it using real-world measurements and ergonomics to fit a person into the space comfortably. Don’t worry though, we are here to help!

  1. 1

    Make Elevation Drawings of your Design

    It’s very crucial to construct 2D elevation drawings of your 3D design, making it easy to plan what dimensions you need to figure out. Elevation drawings include:

    • Plan view
    • North, east, south, and west elevations
    • Section view (to see the gradient of the site for planning out stair and ramp ergonomics)

  2. 2

    Research into Design Principles and Ergonomics

    From these elevations, you can not only plan out what plants will be situated where depending on site conditions and aesthetics, but you can write out measurements, based off of the existing dimensions of your site (using a regulating line), and using research into landscape design elements and principles for aesthetic mathematical design and ergonomics for functionality.

    Ergonomic measurements to figure out include:

    • Stair gradient - tread width and rise
    • Ramp gradient
    • Seat dimensions
    • Bench/table dimensions
    • Doorway widths and heights
    • Structure head heights

    .

    Resources on recommended dimensions are found below in the ‘SUPERSIZE ME’ section, but you may want to find some extra resources on your own.

    Watch Tutorials and have a Play on SketchUp

    If you are unfamiliar with SketchUp, we recommend watching the beginners tutorial videos below to increase your understanding of the tools. After this, have a play around on SketchUp to get a hang of how it works, before you get into building your design.

    If you are already familiar with SketchUp, take your 3D drawings and 2D elevation drawings of your design, and start using them to construct your design in SketchUp.

Adding Real Backgrounds to SketchUp Images

    Enhancing your SketchUp Images

    To enhance the look of your SketchUp models, you should edit the images you take of them to include your chosen site in the background of the model, making them look extra real.

    To do this, you can use any photo editing software that allows you to add layers of images which you can combine together, such as Photoshop. A free option for those using Apple devices is an app called ‘Photoleap’. Here is a quick step-by-step tutorial on how to add an image of your site to your SketchUp Images.

  1. Make your SketchUp Model on a Site that Resembles the Real One

    It’s best to use the measure tool on Google Earth to get a rough size of your site. You can replicate the shape and length of your site on SketchUp, it just may take a bit of fiddling around.

  2. Save your SketchUp Images as PNGs

    When you save images of your SketchUp model, click the option to save them as PNGs. This will mean that the image only physically consists of what you have built, and not the sky/ground around it.

  3. Take an Image of your Site

    This image needs to be taken in the same orientation that the image of your SketchUp model is taken (so they can seamlessly merge).

  4. Download Photoleap and Edit

    Photoleap is a free photo editing software that can be found in the Apple Appstore. When on the app, press ‘Edit photo’ to add the first layer (the background), and then press ‘Import’ to add the second (your SketchUp model).

  5. Cut Out the Second Layer

    With the second layer in, adjust its size so that it aligns with the first layer (becomes to scale). Then, press ‘Cutout’ and ‘Erase’.

    Press cutout and erase

  6. Erase the Unwanted Parts

    In all the areas where you no longer want that part of the image because it interferes with the look of the model being on the site, simply zoom in and swipe back and forth to erase. Mistakes can be easily reversed by pressing the back arrow button at the bottom left corner of the screen. When done, press the tick to save your progress.

  7. Merge the Layers

    Now, press the ‘Layers’ button, appearing as paper stacked on top of each other at the top of the screen (now on the left side of the screen in the latest update), and then press ‘Merge’. Ensure that you are merging the second layer (the image of the model) to the first layer (the site image), otherwise the model image will be hidden under the site image.

  8. Export as a JPEG

    Now, press the export button at the top right of the screen, and save your final edited image as a JPEG, which is commonly the most preferred format for use in other places. You can also save it as a PNG if you want some part of the image to be transparent.

  9. Email the Edited Image to Yourself

    Finally, email the finished image to yourself, and put it into your digital portfolio.
