"Essential Living Construction (and specifically Oscar Barajas) did a great job helping me with my home remodel. The price was fair, the work was done quickly and the results were impressive. Cracked damaged ceiling drywall was replaced with new drywall throughout the entire house and it looks great. Oscar is a friendly, soft-spoken professional and I would absolutely work with him again."

"Rebaza did a terrific job of removing a huge number of bushes that had grown much too high over the past 30 years. The oleander plants especially were a fire hazard. It took Rebaza about three eight-hour days to do the work of heavy pruning and cutting and then dragging everything out to their trailer. Excellent and professional work."

Architects questions, answered by experts

Building designers charge between $2,000 and $50,000, depending on project scope, complexity, and customization.

You have three options in terms of professionals who can draw up blueprints: a draftsperson, an architect, or a structural engineer. A draftsperson can sometimes draw up plans for new construction, but they more often work from approved plans for alterations or to provide 3D drawings. Architects are usually the best option for standard residential construction projects. Structural engineers might be necessary for custom home builds or for alterations that could affect your home’s structural integrity. Draftsmen cost the least of the three, followed by architects and then structural engineers.

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.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.

Yes, architects help navigate local zoning laws, acquire necessary permits, and ensure compliance with regulations, reducing delays and costly modifications.
