The plans for your building or remodeling project can come from yourself, a professional designer, a stock plan book (for a new house), or from a building contractor, who may or may not have special training in design.
In many cases, the plans are a hybrid. For example, you may bring some magazine pictures, hand-drawn sketches, or stock plans from a plan book to your designer or contractor, and collaborate on a finished plan. In most states, anyone can design a house or remodel, with or without specific training – or talent, judging by the many bad house designs that get built. The most common options are discussed below:
Many people have a pretty good idea of what they want built. If you know what you want and can convey it in a drawing, take the plan as far as you can on your own. Then bring it to a draftsperson, professional designer, or contractor to add the necessary technical details. There are a variety of inexpensive, even free, software programs that you can use to design floor plans or entire houses — see Design Software below.
If you can’t produce a drawing, bring some photos, tear-outs from magazines, or stock plans to your contractor or designer. If you know more-or-less what you want, it’s best to point the designer or contractor in that direction. This will save you time, money, and aggravation and you’re more likely to end up with a design that’s right for you.
Where to find great free design ideas. While I used to thumb through magazines and books for design ideas — and still do on occasion — the greatest collection of ideas now lies on the internet. Search Google Images for “kitchen islands,” “mudroom storage,” “half-wall room divider,” or just about any design detail you are working on. What might have taken hours to find in a bookstore or large magazine rack, now takes minutes on the internet. Print out any photos that look appealing and add them to your pile of design ideas — or bring them to the designer or architect you are working with. You rarely find the exact thing you are looking for, but photos can get your creative juices flowing and help you and your designer home in on the design and details that are just right for you.
For a new home, plan books are a good place to start. There are hundreds of plan books, web sites, and CD-ROMs, and thousands of house plans to view. You can find collections of traditional plans, vacation homes, Victorians, contemporaries, bungalows, or whatever is your passion. Many of the older homes that we consider classics today were built from the stock plans of yesteryear.
More and more stock plans are now available with computerized 3D renderings of the interior and exterior, giving you a much better feeling for the look and feel of completed building.
If you see a plan you like, you can use the small-scale illustration and floor plans as a starting point, for free, or purchase a full set of plans for several hundred to a few thousand dollars, depending on the service you are using and the options you choose. Plans by well-know architects may sell for several thousand dollars.
Many companies will make basic modifications to the plan for a reasonable cost and may offer options, such as 2×4 vs. 2×6 walls, slab foundation vs. full-basement, etc. Regardless, your contractor will most likely need to fine-tune the plans to meet local building and energy codes.
You can also buy the stock plan and hire a designer or draftsperson to make changes on an hourly basis, which is an economical way to get a semi-custom design that suits your particular tastes and needs. If you end up redesigning the whole thing, however, you’d be better off bringing the little, free pictures from the plan book and starting your drawings from scratch.
Many stock plans also offer material lists and cost estimates based on your zip code. I’d take the cost estimates with a big grain of salt, but at least it will get you in the ballpark. In estimating costs, make sure you take into account all the costs of site development, permitting, and other costs above and beyond the building itself.
In days of yore, skilled draftpersons drew precise construction drawings by hand. Nowadays it is done almost exclusively on computer. An experienced architectural draftsperson is very familiar with standard building procedures and codes in their area, along with basic structural design. They can take a rough sketch you bring them and turn it into a set of working construction drawings that you can use to get bids and a building permit. This is a very economical approach if you have a pretty complete design that you are satisfied with.
Many draftpersons have design skills as well – they may have some architectural training and/or experience designing houses but never got licensed as an architect. If you are expecting creative design work, rather than just producing professional construction drawings, discuss your expectations and check out their design work before proceeding.
A variety of different professions design houses and remodeling projects: architects, designers, and kitchen & bath designers, among others. In general, architects have the most training and charge the most money, but they do not necessarily have the most experience in designing houses. Most architects make a living designing large public and commercial buildings and may only design the occasional house, or none at all. So, if you choose to use an architect, make sure they have ample experience designing homes and have a design style that appeals to you.
A good architect or other professional designer will ask you a lot of questions and develop a design that they think will meet your needs. They are likely to offer creative solutions that didn’t occur to you, and which you may like or not. In the best case, it’s a collaborative back-and-forth effort that produces a design that uniquely fits the building site, your specific needs and desires, and your budget — usually the biggest sticking point!
Whatever person you choose, look at their portfolio of designs and, if possible, visit some completed projects. As with any key member of your team, get references and talk to past clients. Ask if they are happy with the work, did things go smoothly, and were there many changes, cost overruns, or delays that they attribute to the designer (as opposed to the owners changing their minds mid-project).
Contractors who offer design as part of their service often identify themselves as design-build contractors. These contractors generally work on a negotiated bid, and have a fee system that covers the design phase of the project separately from the construction phase.
Other contractors do a little (or a lot) of design here and there, but don’t charge for it separately and don’t generally promote themselves as professional designers. They may not even consider themselves designers but, in fact, they are doing design work.
Using a design-build contractor has pros and cons. In brief, you get many of the benefits of hiring an independent designer with less cost and complexity. On the downside, you lose the checks-and-balances that come with an independent designer, especially if you are paying the designer to oversee the construction phase.
Letting a regular contractor provide you with “free” design may be fine for small projects such as deck, porch, kitchen and bath remodel, or small addition. If they have a lot of experience at this and a good design sense, their work may be as good or better than what you would get from a professional designer. As with any other designer, look at their other work, check references, and if you like what you see and hear, you should be fine. As with other designers, point your contractor in the right direction with magazine clippings, stock plans, photos, or sketches that illustrate the appearance and features you are looking for.
The CAD (computer assisted design) programs developed for architects and other design professionals are expensive and very complex with a long learning curve. Over the past several years, however, a number of inexpensive software programs have been developed for homeowners, contractors, and designers to quickly produce professional looking building plans.
I’ve yet to find a program intuitive enough to use out of the box without some effort and several hours of fumbling about. However, once you get the hang of it, you’ll never go back to tracing and erasing to modify and tweak your drawings. And unless you are blessed with the ability to easily visualize 3D spaces, you’ll find the new 3D programs a great help. The programs let you view your design from any perspective and to walk through the space as if it were the real thing – with furniture, plants, and shadows.
3D Software. My favorite program is the original 3D Home Architect from Broderbund, which was a simplified version of the professional CAD program Chief Architect – basically an earlier version of the professional program with a number of features turned off. You could easily create respectable 2D floor plans and basic 3D renderings. The 3D images were very basic compared with the current crop of photo-realistic 3D programs and the dimensions were not always precise, but it was fast and flexible, and produced good enough drawings for preliminary design by either homeowners or professionals.
Unfortunately, older versions of 3D Home Architect do not run on most modern computer operating systems. Numerous newer versions of the program now available, some from Broderbund and some from Chief Architect. I have not tried the newer Broderbund products, but most have gotten very mixed reviews – more bad than good. As with too many software programs, they have added lots of features, but have made the program slower, more complex and difficult to use and, in some cases, very buggy.
The most recent low-cost version from Chief Architect, called Home Designer, has been well received by both homeowners and professionals. The least expensive version, Essentials, costs a mere $60. I am currently testing the next version up, Home Designer Suite ($99), and will report back later on its ease of use and performance. See sample images below.
Google SketchUp. This free 3D design program from the Google empire is getting rave reviews in many quarters, from homeowners and contractors to architects and engineers. People accustomed to traditional CAD programs have a difficult time adjusting to SketchUp’s entirely different approach to drawing, but many have found it worth the effort. There are many online tutorials and learning tools, as well as a large online user community, to help you learn the ropes. Also, users have created a huge library of architectural and other objects which you can download for free and add to your drawings. I spent several hours with the program and was able to create most basic building shapes, but still had a lot of trouble creating accurate and professional looking architectural details.
Once you get the hang of it, Google SketchUp lets you quickly create just about any shape object and stretch, rotate, penetrate, duplicate, and manipulate it till the cows come home. Its great power and flexibility are also its greatest challenge when you are learning the program. It’s easy to hit the wrong key and all of a sudden your building looks like a twisted Escher print where you can’t tell inside from outside. Also, it is not strictly a building design program, so it does not have dedicated tools for drawing walls, windows, and other building components. However, you can create or download (from the Google “Warehouse”) building components, modify and resize them, add textures and colors to them as needed, and add them to your drawing.
If you just want to create 2D floor plans, SketchUp is probably not the easiest tool to use. You can trick it into creating 2D drawings by viewing the drawing from above (select Camera > Standard Views > Parallel Projection), but it is probably not worth the effort unless you plan to use the 3D modeling and rendering tools.
BENEFITS OF 3D DESIGN SOFTWARE
Nearly all design programs today can generate realistic 3D views of the building’s interior and exterior, and allow you to view the building from any angle or even to walk through the space. Since most people have a hard time visualizing a building from a set of 2D drawings, this is a powerful tool that can help you evaluate a building design and make changes while it is still on the drawing board.
If you are working with a designer or design-build contractor, ask if they can provide 3D drawings or computer images for you. It will be money well spent if it enables you to fine-tune your design at the planning stages – not when the house is half built and you decide it’s not what you really wanted.
