Can I modify stock house plans? How long will it take?

Yes, we offer modifications to our plans with free quotes at reasonable rates. At Old Barn Design, we understand that you want your plan to be modified to suit your exact needs and any of our house plans can be changed accordingly. Please give us a call at 469-693-1108 for more information. You may also take this plan to your local draftsperson, architect, or builder for changes.  These plans are created in SketchUp (.skp or .dwg files) so we recommend using someone familiar with that format.  It is possible to work with these drawing in AutoCAD using a free extension.  If you want to hire someone to make modifications, you’ll want to order the .SKP/.DWG version instead of the PDF version.


What do I do after purchasing my plans from you?

The first thing you should do is contact a builder and your local building & planning office. You MUST get the specific requirements from your local building department. You or your builder will also need to contact a local engineer to get the foundation designed for your specific site conditions and local codes. The foundation drawing in this set is for planning, estimating, and layout only. At Old Barn Designs, we provide “working drawings”. There are no engineer or architectural stamps/sign-offs. Engineering is not provided with any plans and should be provided by your own hired, local Engineer, since they would need to be familiar with YOUR local building codes and conditions such and wind, snow and earthquakes.


What types of foundations are available for my house plans?

Many times changing a foundation type is a very simple matter and can be done during construction. Our plan is drawn with a standard post-tensioned slab but can be modified for basements, crawl spaces, etc. It is recommended to have your foundation engineered by a local professional based on soil and local conditions. Please call (469) 693-1108 with any questions.


How do I order the house plans?

Just go back to the plan page click on “add to cart” and continue with the information requested.


Can I see rear and side elevations or more artwork and photos?

Yes. Our designs have rear and side elevations available upon request.


What does “living” square footage mean?

Generally, square footage is calculated as the finished (dry-walled, painted, carpeted), under heat and air square footage. It would include footage from outside framed wall to outside framed wall (not including brick, siding, stucco etc.), and anywhere the floor joists would project, such as in a cantilevered (overhanging) bay window. Other things that are typically not included in a home’s square footage are garages, front, back or side porches, courtyards, patio, etc. Basements are also not included in the square footage unless they are finished. All room sizes shown on floor plans are rounded off measurements.


If I decide I don’t like the house plans, can they be returned?

Unfortunately, no. Since it is possible to make illegal copies of the plans you received, we do not allow any refunds. You need to make sure of your order before placing it. It is also VERY important that you check the dimensions of your lot or land before selecting a house plan.


What codes do your plans comply with?

Our plans are designed to specifications published by the International Residential Code, (IRC), and the Uniform Building Code, (UBC). This plan is designed to meet or exceed the national building standards. Because of the great differences in geography and climate throughout the United States, each state, country, county, and municipality has its own building codes, zone requirements, ordinances, and building regulations. Your plans may need to comply with the local requirements regarding snow loads, energy codes, wind loads, soil and seismic conditions, and a wide range of other matters. Please check with your local building authorities before making your purchase. Most plan can be adapted to comply with a few simple additions and notes by a local engineer.


How many times can I build the plan I purchase?

As a registered purchaser of a plan, you are licensed to build only one structure from the plans. If you intend to build a plan more than once, contact us to obtain a quote for a multi-use license.


What is mirror reverse?

A mirror reverse is exactly like looking at a set of plans in a mirror.


Do you offer custom design work?

Yes, at this time I am only offering services to make small modifications to the plans sold on this website. There may be a waiting list for my services.


Do your plans come with a material list?

No, full architectural drawings never include a materials list. This list is compiled by the materials supplier, you, and your builder. It is tailored to availability, suitability, preference, and cost. Generic materials lists which are often available with stock plan purchases, are of marginal use when getting an estimate, and of little to no use for bids or construction.


What are home building codes?

Building codes are safety regulations pertaining to how a building (commercial or residential), should be built. They are intended to protect both builders and home buyers from building an unsafe structure. They deal with everything from nail spacing to wheelchair accessibility. Many restrictions, regulations and inspections are regionally required due to soil conditions, weather conditions, etc. Every state, county and local municipality has adopted some form of one, any or all of these standard building codes.


Do these house plans meet my local building codes?

Our house plans are designed to meet or exceed IRC and average conditions and codes in the State of which they were designed. Because codes and requirements can change and may vary from jurisdiction to jurisdiction, Old Barn Design cannot warrant compliance with any specific code or regulation. All of our plans can be adapted to the local building codes and requirements. It is the responsibility of the purchaser and/or builder of each plan to see that the structure is built in strict compliance with the governing municipal codes (city, count, state and federal). In addition to the complete building plans that you order, you will also need a site plan that shows where the house is going to be located on the property. Your builder can usually help you with this. You may also need a septic design unless your lot is served by a sanitary sewer system. Many areas now have energy codes that have to be followed. This normally involves filling out a simple form proving compliance. There are some areas of the country that have very strict engineering codes. Examples of this would be earthquake-prone areas of California or hurricane risk areas on the Florida coast. If you are building in this type of area, it is possible that you will need to hire a local engineer to analyze the house and provide additional drawings and calculations required by your building department. If you aren’t sure, building departments always have a handout they will give you listing everything you need to submit for a building permit.


Can a contractor or I actually build a home from your house plans?

Yes. Our plans include most everything you need to build, including elevations, floor plans, foundation plans, electrical plans, roof plans, etc. Important details, such as where the home will be located on your site, and how the water, sewer, and electrical hookups are made, is something you will need to address with your contractor and local building inspector. You will also need to have a local engineer design the foundation based on your specific site conditions. The foundation plan in this construction set is for estimating and locating purposes.


How much will it cost to build the home I want?

You will need a set of plans to present to your builder who will prepare a detailed estimate.
