Building a Timber
Frame Home: A Consumer's Guide:

Timber Frame Home
The purpose of this Guide is to provide you with
a basic understanding of the process of planning, designing and
building a timber frame home.
As in any custom-built house, your timber frame
home will require your input and will ultimately reflect your
personal preferences and requirements.
In this section, we provide a brief summary of
the professionals who will be needed and how you might go about
selecting them.
The Guide will help you sort through your options
as you decide how involved you want to be. There are a number of
different directions you might choose to take. You may find it
helpful to check off the boxes as you read through the Guide.
It is our intention that this Guide clear up some
of the grey areas that, if left unattended, could lead to
unfulfilled expectations and misunderstandings.
In our experience, even though people are
attracted to building a timber frame home, they have little
building experience and no knowledge of what role they might have
to play in the construction process. Many of our customers have an
idea of what they want, but they experience difficulty putting
their ideas on paper.
And finally, while superior quality and
uniqueness are the ideal, home owners must be prepared to justify a
greater investment of both time and money when designing and
building a timber frame home compared to a more typically
constructed home.
We are eager to have our clients understand the
basics of the process. By working together, we know our combined
efforts will result in an improved product, a streamlined design,
contracting and construction process, and an enriched experience
for us all.
Designing and building any new home can be
exciting. Working on and completing your timber frame home can be
cause for a true celebration. Knowing the necessary steps and which
questions to ask will make it that much more enjoyable.
Preliminary
Research
Planning and building a timber frame home is a
unique opportunity to build your dream home. Here's how you start.
First, gather some ballpark information to help you decide if this
process is for you.
Talk to professionals who know the timber framing
process and who can help you understand the value and costs of this
building system. Timber frame companies have resources to answer
your questions. Local architects, designers and construction
contractors are also good sources of information.
Read books and
magazines.
Rough out your preliminary budget and consider
getting "pre-qualified" at one of your local mortgage lending
institutions.
Collect literature from timber frame companies by
attending their home building seminars, workshops or schedule a
visit to their building sites, open houses, or model
homes.
Gather information about different companies'
products, services, and average costs.
At this point you may discover that different
timber frame companies provide a wide variety of products and
services and it may be a bit confusing. You'll need three primary
services.
First, the entire home must be designed; then a
timber frame must be fabricated and raised; and finally, the pieces
of the home must be pulled together and built. Some timber frame
companies offer complete design and general contracting services;
some offer design and fabrication services; and finally, some just
design and erect the timber frame itself, but do not handle overall
construction services. Decide if you want to assemble and manage
your own team or whether you would prefer to hire a contractor to
take on these tasks.

Getting
Started:
|
|
YOUR BUILDING SITE
Whether you already have property or are still
looking for that perfect location for your new home, you should
think about these issues. Your aesthetic requirements and practical
considerations can both be met. Try to define the qualities you are
looking for in your homesite. Is it wooded or open, sloped or flat,
remote or close-in? Proximity to schools and municipal services can
be important factors. Here are others to consider:
You will need access to utilities. This includes
essentials such as water, telephone and electrical service, and
sewage disposal as well as optional hook-ups for natural gas or
cable television. Be sure to investigate the connection costs
associated with these services, as well as permit fees.
The costs for building roads and driveways to
access your property or for bringing utilities to the site can be
daunting. Be sure you have the full picture.
Existing zoning regulations and setback
requirements may not meet your needs. If you must request a
variance, be sure to factor response time into your
plans.
Be certain your lot has a soil type suitable for
building, and that it will pass a perk test.
Topography can have a substantial impact on your
costs. Sites that are steeply sloped, rocky, heavily wooded or
otherwise difficult to access can add significant time and expense
to your project.
Solar access is critical if you are planning a
passive solar/daylit home or want to include
photovoltaics.
Consider natural conditions such as local
climate, prevailing breezes and indigenous vegetation that will
impact the energy, performance and comfort of your new home. Taking
advantage of these conditions allows your home and building site to
stay in harmony with its surroundings.
Evaluate the "view potential" of your proposed
site.
Members of your design and construction team can
help you site your home to identify the optimum spot on your
property with the best views, proper solar access, best drainage,
etc.

|
ASSEMBLING THE TEAM
You will need an architect or designer, a timber
frame company and a general contractor on your team. Remember, some
timber framing companies offer all these services as part of a
turn-key package. There are some issues associated with each of the
team members and some questions you might want to ask. You'll
achieve the best results when all of the selected professionals are
committed to working together and are very clear what you expect
from each of them.
|
|
HOUSE PLANS
Your investment of time and money in the design
process will vary depending on whether you choose to design a
custom home from scratch or purchase a previously prepared set of
plans. You may decide to work with a timber framing company that
has a portfolio of plans from which you can choose. There are also
other sources of home plans that may be a helpful reference as you
are developing your building program (the list of requirements for
your new home). But, unless a plan is developed with timber framing
in mind, it is likely to require significant modification to
accommodate timber framing and the variables of your
site.
A note of caution: Be aware that the penalties
for copyright infringement can be severe. Be sure you either
purchase a published plan, use a plan from your timber frame
company, or work with an architect or designer to create your
own.
|
|
SELECTING AN ARCHITECT OR DESIGNER
Choosing the right architect or designer for your
timber frame home will make a significant difference in your
satisfaction with the final results. Many timber frame companies
offer either design services for completely custom homes, or have a
portfolio of plans from which you can choose. Some offer both.
Still others can recommend designers who are experienced with
timber frame construction.
It is best to have your designated architect or
designer work directly with a timber framing company early on in
the design process to avoid any duplication of services and to
ensure the integration of timber framing details into your
plans.
Some companies ask for a modest, up-front
deposit. Be sure you are clear on what this fee covers. You will
probably be asked to make a series of payments during the process.
Find out from your designer/architect how the payment schedule is
established so you can budget accordingly.
When considering candidates to design your home,
you should be able to see several examples of the designer's work,
if not in person, at least in pictures. Request a list of
references and call their previous customers. You can learn a lot
by asking a few simple questions. Did they deliver on time and
within budget? Were they responsive to the client's
needs?
You should also have good rapport with the
architect or designer you select. If you are designing from
scratch, you'll be working very closely for several months on what
undoubtedly will be an intensely personal project. Here are some
questions for your potential designer/architect.
Are you familiar with timber frame construction?
Can I see examples of your work?
If "no" is the answer to the first question, ask
if they are willing to collaborate with a timber framing company in
the design of your timber frame home and enclosure
system.
Do you guarantee your design will meet or exceed
applicable building and energy codes?
How long will it take to get complete
plans?
How much will your entire design service cost?
How will I be billed?
Who will design and engineer the timber frame?
Does your firm have a licensed engineer or architect who is
authorized to "stamp" (approve) my plans?
Whether you design from scratch or work with a
purchased plan, a thorough set of construction documents will be
required for obtaining building permits and financing, and for
completing construction. These documents form the basis of the
contract with your builder.

SELECTING A TIMBER FRAME COMPANY
The role of the timber framing company may vary
from project to project and company to company. They may serve as a
subcontractor, a general contractor or a specialty construction
consultant. Timber framing companies differ in the size of their
operations, their style of timber framing, and the scope of
products and services they offer.
Your preliminary research should give you a good
idea about which level of service you prefer. The selection of the
timber framing company then becomes one of finding a company that
matches your needs. As with the selection of the design
professional, you should see examples of the timber framing
company's work and feel comfortable with the people who will be
responsible for your job. You may want to check them out with the
Better Business Bureau or the Chamber of Commerce. Here are some
questions you may want to ask potential timber framing
companies:
- What services and products do you
supply?
- How long have you been in the timber framing
business? How experienced is your crew?
- Are you willing to consult with my designer
and/or builder throughout the project?
- Which type of wood do you use? Can you explain
some of the characteristics and advantages of different
kinds?
- Who raises or installs your timber
frames?
- What type of enclosure systems do you use? What
are the advantages of each? Who will install the enclosure
system?
- What type of warranty do your products
have?
- Do you maintain workers compensation insurance
and the license(s) and insurance required by our state and local
governments?
- May l have a list of your client
references?

SELECTING A GENERAL CONTRACTOR
The general contractor is responsible for the
actual construction of your home. They take the house from
foundation to finish. It is important to note that one company's
services can vary from the next. However, most general contractors
coordinate all the labor and materials. It is their job to deliver
your house on time and within budget.
During the construction process, the contractor
will manage your job site, supervise all the workers installing
plumbing, roofing, electrical services, and much more.
These workers may be on the general contractor's
staff or they may be hired as subcontractors. There are both pros
and cons to subcontractors.
Be sure you ask what the potential pitfalls might
be. What about using local subcontractors if your general
contractor is located in another town? What about access to these
"subs" a year from now if you have a problem? Do these
subcontractors work with this general contractor on a regular
basis? This may mean they have established a good track record
together. Be sure to ask. |
|
|
The role of the timber framing company may vary
from project to project and from company to company.
Your general contractor should be detail-oriented
since they will coordinate all payments, maintain records, develop
and implement a construction schedule and officiate bids to make
sure they are inclusive of all proposed work. Their experience can
be of great value during the design phase of your
project.
While experience with timber frame homes is
helpful, it is not absolutely necessary. What is important is that
the designer and/or the timber framing company are able to
communicate to the contractor the construction details unique to
timber framing.
Finding a qualified contractor in your area is
not difficult. You can begin by consulting acquaintances who have
built custom homes or you can check with your local home builders
association.
Here are some questions to ask potential general
contractors:
- How long have you
been in business?
- Have you had
experience with timber framing?
- Have you worked with
a particular timber framing company?
- Will you consult with
my designer or architect on the feasibility of construction and
cost of a proposed design?
- What is your
preferred form of contract?
- How do you handle
change orders?
- How long will it take
to build my house?
- May I have a list of
client references?

UNDERSTANDING CONTRACTUAL RELATIONSHIPS
In all cases, when you are contracting with any
of your team members, check their references, and insist on a
complete, written agreement for all products and
services.
What type of contractual relationship will we
have?
What type of contracts will you enter into with
others as you work on my home?
What costs are not included in your
contract?
If you opt to seek competitive bids for your
timber frame, remember that fair and accurate bids are only
possible with complete and detailed timber frame plans. Timber
sizes, grade and species, and connection details should be clearly
specified.
The completeness and quality of the construction
documents is critical. These documents are the basis for all
contracts and the clearer and more complete they are, the less
likely it is that questions or disputes will arise later. Your
contract with the general contractor should include a start date
and a completion date.
Be certain you know just how long the
construction process will take. Some communities have limited
periods when building is permitted. This schedule will also dictate
the timing foreseeing your existing home or completing your lease
on a rental property.

|
UNDERSTANDINGTHE DESIGN PROCESS
Custom design is an interactive process that
requires communication, reflection, revision and refinement. Both
flexibility and decisiveness are needed. It is a multi-step process
that requires increasing levels of commitment as you
proceed.
Not only will good design add value to your home,
the process should be an enjoyable one that results in a home that
fits you well. Here's a bit about each phase.
|
|
PROGRAMMING& SCHEMATIC DESIGN
The first step is to develop your building
program. Initially, this might be a loose description of functions
or activities that you wish to support within the house, as well as
considerations of view, solar exposure, natural light and other
site-related factors.
Your initial program should also include a rough
idea of the number of rooms you require, a general idea of the
overall size of the house, information about your preliminary
construction budget and a notion of the feel you are trying to
achieve: rustic, contemporary, open, private.
Your designer or architect will help you create a
more detailed program which will result in the first schematic
design – typically a set of hand-drawn sketches or CAD drawings of
floor plans and one or more exterior elevation.
It may require one or more revisions before you
arrive at a version of the plan that you wish to develop
further.
At completion of the schematic design, you should
receive a rough cost estimate for the entire house. While many of
the construction details remain to be defined, a preliminary cost
estimate based on the schematic plans will be more accurate than
the ballpark costs you collected earlier and will be a valuable
reality check.
Depending on which process you have chosen, you
may already have selected the timber framing company and general
contractor with whom you wish to work.
Their input is especially valuable during this
phase of the design process. If you aren't ready to commit to one
single firm yet, consider retaining a timber framing company and
general contractor as consultants.
The results of the preliminary pricing exercise
may direct you back to the drawing board to revise or refine your
concept, but it's better to do it early in the process rather than
after the design is further developed. Remain flexible and open to
compromise.
|
|
DESIGN DEVELOPMENT
With approval of the schematic design, the design
team will prepare more detailed drawings to illustrate other
aspects of the proposed design. Floor plan drawings will show all
rooms in correct size and shape. Exterior elevations and a typical
building cross-section are drawn to scale. You will begin
determining specifications for major materials and room finishes.
You can expect a more detailed, and therefore, more accurate cost
estimate as part of this phase. Upon your approval of these (design
development) documents, you will move on to creating construction
documents.
|
|
CONSTRUCTION DOCUMENTS
In this phase, construction details and
specifications are completed to be in compliance with the local
building code. You can expect the final and accurate price at this
stage.
The level of detail required for the latter may
be influenced by the type of contractual relationship you have with
your contractor. The drawings and specifications completed in this
phase become the basis for financing, permits and any future
construction contracts.
Note: Please keep in mind that design development
and construction documents may cost a modest fee.
|
|
ADDITIONAL SERVICES
Depending upon how you have assembled your team,
you may want to have your architect or designer assist you with
soliciting and reviewing bids and negotiating contracts with the
timber framing company and/or the general contractor.
In addition, the design team may serve as
administrator of the construction contract, assuring that
construction is in accordance with the construction
documents.
And finally, your architect or designer may be
able to provide interior and landscape consulting services, or will
collaborate with specialists in those fields.
|

CONSTRUCTION
Construction is where it all comes together, and
the plans you've made become a home. While there are many
variations, they all begin with a contract which should serve as
your guide for the duration of the project.
There are three major types of contractual
relationships: a fixed price, cost-plus-fee, or construction
management. You may arrive at any of these by either a bidding
process among a number of potential firms or by negotiating
directly with one or two.
All of these options have advantages and
disadvantages and should be considered carefully.
A "fixed price contract" means that the timber
framing company or general contractor agrees to build the house as
shown on the construction documents for a set price.
Usually there are allowances for appliances,
finishes, cabinets, lighting fixtures, etc., which can be modified
by a Change Order. Therefore, the "fixed price" is a bit
misleading, unless there is an unusually complete set of
construction documents and no changes are made during the
construction process.
Because this is unlikely, another approach is the
cost-plus-fee contract, which may include a "not to exceed" clause.
In this case, after preparing a budget, the general contractor
agrees to build the home at his or her cost plus a given fee for
overhead and profit.
The advantage of this form of contract is that
making changes is easier, and the owner pays only for what is
provided, plus a fair profit margin. The disadvantage is that you
don't know exactly how much the finished home will
cost. |
|
|
Often the timber frame and enclosure system are
very clearly defined early in the planning process. Therefore, a
variant of the above is often appropriate, with a fixed price for
creating and erecting the timber frame and a cost-plus agreement
with a general contractor for the remainder of the home.
Bear in mind that the timber frame is just one
component, and contracting for a frame without solid cost
information for the complete home is inadvisable.
You may wish to obtain two costs from your
general contractor: (1) shell erection to weather-tight and then
(2) interior finishing. This will allow you to adjust, as required,
if you experience additional costs during the initial erection of
your structure.
|
|
CONCLUSION |
|
|
By conducting preliminary research, enhancing the
features of your building site, and thoughtfully selecting your
timber framing company, architect or designer and general
contractor, you can avoid a lot of frustration while saving time
and money. With careful planning from the design process through
construction, you will soon be the proud owner of a beautiful new
house.
A well-designed and well-constructed timber frame
home can provide a richly rewarding living experience for years to
come. Good luck! |
