this handy guide to design an addition to suit your home and your lifestyle.
Maybe a new family member has arrived. Maybe
you’re tired of cramming your family into a tiny kitchen, or maybe you are finally
building the master suite you’ve dreamed about for years. Whatever your reason
for wanting to add on to your home, you know you need more space. But how do
you go about building the much desired addition?
We
have broken down the planning process into five basic steps to guide you from
compiling ideas, to determining a budget, to choosing professionals. It is not
so overwhelming when you take it one step at a time, so take a deep breath
and dive in.
Step 1 : Compile a project wish list
Although the early stages of a remodeling
project often include ideas sketched on a napkin, the best starting point is a
wish list a compilation of elements that will shape or influence the design.
Making a list helps you communicate with prospective designers or contractors.
Identify key objective
Start your list by asking yourself what you
want the project to achieve or what problems you want it to solve. If you are
planning an addition, you obviously need more living space area. Maybe you also
need to improve your home’s traffic flow pattern or boots storage capacity. Or
do you need more convenient indoor – outdoor access or more entertaining room?
Get inspired
To bring your wants and needs into cleaner
focus, allow yourself plenty of dream time. Fill a scrapbook with photos and
plans clipped from your favorite home design magazines. Check the buying guide
sections for information on products and materials. Pick up books or watch TV
show that feature remodeling or redecorating projects. Glean ideas and
inspiration by touring new and remodeled homes in your town.
Choose some savvy splurges
Decide which special features fireplaces, a
kitchen island or an elaborately outfitted media wall
are most important to
you. Even if a feature seems costly, don’t rule it out right away. You maybe be
able to splurge on a couple of items and economize elsewhere.
Not all must have items are costly. Laundry
chutes, for examples, are relatively cheap to build but require careful
planning at an early stage. Getaway spaces cozy nooks and crannies that offer
spots to curl up and savor quiet moments often make use of otherwise unused
spaces, such as landings, dormers, and jogs in hallways,
Step 2 : Size up your situation
You have had your chance to dream. Now it’s
time to head back to reality and take a look at the real life factors that play
a role in your project. Recognizing limits or constraints ahead of time heads
off wasted efforts and disappointments later.
Calculate your clout
First, figure out approximately how much
financial leverage you have to cover the cost of the project or to swing a home
improvement loan. Take stock of your major assets, such as the equity built up
in your home, your accumulated savings, and any of your investments (stocks,
bonds, and other securities) that are easily liquidated.
Also you consider your credit rating, your
monthly payment and any do-it-yourself skills you plan to apply to the project.
An excellent credit rating and a low number of large monthly payments give
lenders extra confidence about your ability to repay a second mortgage or home
improvement loan. If you plan to cut costs substantially by doing some work
yourself, be sure to cite it as part of your assets. Not only will your labor
reduce your debt load, but it also conveys your commitment to the projects.
Check out the site
Take a close look at the building site, or
where you plan to construct the addition, plus the areas around it. Consider
the location of tress or outbuildings you want to preserve, views you want to
capture( or screen out) and exposures to sun, shade, or prevailing breezes.
While you’re at it, be sure to check for obstacles you need to remove,
relocate, or work around, such as power lines, utility poles, and underground
fuel or septic tanks.
Run it by city hall
Be sure to also look into the legal
restrictions regarding what can be built on the property. Often setback
restrictions govern how close a structure can be built to properly lines. Other
legal constrains include height restrictions, building area ratios (allowable
ratio of buildings to land), design covenants, and historic district
preservation ordinances, if your project doesn’t conform in some way, you may be able to
apply for a variance (special permission to disregard a particular ordinance)
Crunch the numbers
After reviewing your financial clout and the
construction site, take a stab at crunching the numbers to decide whether
you’re in the ballpark regarding budget.
Survey a few local designer or contractors to
find out the average cost per square foot for remodeling projects in your area.
When you ask for the information, refer to a price points or category that
describes your project, such as budget, mid price or high-end. Once you
obtain an estimate, add 10-20% to cover unforeseen delays and costs.
Step 3 : Consider your building options
Once you form an idea of what you can afford,
it’s time to think more seriously, about the structure of your addition. Here’s
a brief rundown of your opinions.
Add manufactured or stick built construction
A few decades ago, all additions were built
totally, on site, on piece at a time. The stick built method offers the most
flexibility and is still predominant, but manufactured or modular additions
have gradually gained popularity. Some manufacturers now offer a mix and match
of modules, such as dormers, bays and half gables, so an addition merges
comfortably with the shape and style of an existing
structure. Modular constructions dramatically reduces on
site labor. Much interior finish work can be done at the factory, eliminating
weather delays and allowing purchases of materials in bulk quantities.
Create one addition or several
A chief advantage of putting new space under
one roof and on one foundation is cost. Several some additions cost much more
to build than one large one. Also, multiple additions usually require more
design input because each unit must be merged individually with the existing
structure. However, a single addition doesn’t always provide the best option.
In some cases, problems need fixing at opposite ends of the home. Sometimes a
properly lacks the space for a sizable multi room addition but can handle two
carefully positioned single room structures.
Built up or out
For the majority of additions, building out
provides a sensible strategy, but sometimes it’s best to build up instead. On
extremely tight sites, such as in closely built older neighborhoods, no buildable
area remains for horizontal expansion. Some homeowners choose to build up in
order to preserve outdoor living space or to gain privacy for bedrooms in a new
second story. You might get the space you need by raising certain portions of
the roof.
Step 4 : Create a good team
Good projects are the result of teamwork, and
teamwork relies on trust and communication.
Hire the professionals
The number and type of people you need on
your team depends on the scale and scope of your project. Even if you a rather
small addition, you probably need a designer or draftsperson to prepare one or
more working drawings to apply for a building permit, freehand sketches or
rough diagrams normally don’t suffice. For more extensive projects, an
architect can help you come up with the overall design. He or she can design an
efficient layout and merge the addition’s design with your existing house. Then
you need to hire a general contractor to supervise construction.
Another route is to hire a design build firm.
It provides a complete package of services, including design consultation, construction
drawings, and project management.
Costs for services vary widely. For design
consultation, some architects and designers charge an hourly rate ($50 and up),
others charge a day rate or a percentage of the total project cost, usually
less than 7 percent. Straight drafting services are usually billed at an hourly
rate of $15 - $25. General contractors normally charge at least 20 percent over
other costs of the project.
Pick the right people
One sure way to track down good candidates is
by word of mouth. Talk to neighbor and friends to find out if they experienced
good results from a certain designer or contractor. Another good
reliability clue is longevity, area professionals who have been business for
several years likely will be reputable and reasonably congenial, dishonest
contractors don’t usually stay afloat or around long. Take time to interview
and get estimates from several candidates before selecting your professionals. Ask
to see samples of their work, and check with the better business bureau to see
if clients have filled complaints about the company.
Spell out the project in black and white
All reputable designers and builders work
according to terms set forth in a contract, a legal document that safeguards against
misunderstandings and costly calamities. Most construction contracts three
instruments, a text document written
in fairly plain English, a set of blueprints and a list of materials. When you
sign the text document,
you agree to abide by all three instruments.
Contracts vary somewhat, but most include
provisions for the following, a work schedule including inspection dates and a completion date,
a payment schedule, usually weekly or monthly installment, plus a final payment,
statements designating liabilities and insurance coverage in the event of
injuries, theft or damage at the work site and clauses that say the builder
cannot be held responsible for delays that are caused by weather and other
forces beyond his or her control.
If you plan to do some work yourself, spell
it out in the text document, if you will obtain any materials and products on
your own, indicate the items in the materials list.
Step 5 : Bring the design into info focus
A good designer organizes your idea in a
floor plan that fits your life style and steers you past
the pitfalls of poor planning such as dueling door swings, stingy storage, and
skimpy windows.
Visualize the space
Your family lives in a three dimensional
space, not two dimensional plans and elevations, so as your designer sketch’s a
floor plan, try to imagine how the space will function in three dimensions.
Ask yourself on your designer a series of
question as you study the drawings. What will you see when you step into the
space, a dramatic window wall, a cozy hearth area or a bowling alley vista
leading your eye directly to the powder room toilet. Put yourself in various
spots on the plan and think about what you’ll see in the real space.
As you walk through the plan, think about
your family’s daily routine. Is there
ample seating in the gathering area? Will traffic circulate freely around the
sitting space
or will people cut across the room.
Add to scale furniture layouts
If you have furnishings in mind for the new
space, make to scale cutouts of pieces and place them on the floor plan to see
how they fit, if walls need to be shifted, do it now, not after the footings
have been poured. To allow room for large breakfronts or media cabinets, ask
for elevations of the walls and mark off the heights and lengths of the piece
to see if they seem proportional
to the space. Check to see if your
furniture arrangement requires electrical outlets in special locations. Think
about placement of phone jacks and cable hookups.
Request 3-D sketches
If you fins an area hard to visualize and
think it might pose a problem, ask the designer to create a three dimensional
sketch. A 3-D drawing shows how the space will appear when built. Even the most
talented pro can’t predict the appearance of every cubic inch and occasionally
discovers minor goofs during rough framing, dry walling, or finish work.
Crunch the number again
Once you are satisfied with the design, it’s
time to take another look at the numbers, this time, a really hard look,
because you’ll be dealing with real numbers and you’ll be expected to make a go
or no-go decision fairly quickly. If the numbers seem manageable, you’re all
set to put plan into action.
