"I had an addition I wanted for our home. We were required to have a survey and an engineer drawing to apply for the permit. I had a list of 10-15 local engineering companies given to me by the permitting office. Very few would return my call. several the rest said they only do commercial or that this was too small of a job and would cost more. It was taking months and I was frustrated and decided to try Angie’s. I am so pleased. I had a response that very day I inquired for the job. It was clear what was needed from me. Great communication and answered questions to help me get them what they needed. The project from start to finish was drafted within 3 weeks. It could have been done sooner but I was traveling and not able to check emails. Once I told them to text me to alert me of an email they did that. I would highly recommend them."

Yes, you can finance cottage construction through several options. Construction loans provide funds in stages as work progresses, while home equity loans or lines of credit are available if you have existing property. Some lenders offer a combined construction and permanent mortgage. Always review loan terms and payment milestones before committing.

There are differences between universal design and ADA accommodations, but the outcomes are often similar. While universal design is a proactive process that takes a social justice approach to accessibility for all, ADA accommodations are focused specifically on accessibility for individuals living with disabilities. ADA accommodations often take the shape of wider doors and hallways, ramps, elevators, lower counters and sinks, and easy-to-grab door handles; universal design can include these plus emphasize better lighting, tractioned floors, and other building elements that allow all people to use buildings more comfortably.

Utilize CAD software for precision, modern design visualization, and alterations.

Federal and Colonial architecture are similar in that they both appear mostly utilitarian and symmetrical, but Federal architecture is a bit more ornate. Federal design often includes decorative palladium windows, window lintels, and, sometimes, columns surrounding a more decorative portico. Inside, Federal architecture is set apart by its centrally-located oval room. Additionally, Federal homes tend to have brick facades, whereas Colonial homes more often have wood siding.

When you think about Arts and Crafts-style homes, you probably think of a Craftsman house or a bungalow-style Craftsman. Craftsman is one of the major styles developed during the Arts and Crafts movement, but it checks most boxes. Craftsman houses have low-pitched roofs, exposed rafters, open floor plans, and stunning wood finish.
