Free computer drafting with general knowlege of design. I have 30 years experience in building houses. I am familiar with local subcontractors. I can get any job done at a reasonable cost.

"The work was done properly and when some additional jobs were added, Mr Grant went out of his way to get subcontractor's in to fix the added jobs promptly. I was very happy with the results and would recommend Steven Grant Construction to anyone who needed a prompt quote and a properly done job. He took the extra steps to finish my job within the quote so I stayed on budget."

Home Building questions, answered by experts

Some, but not all, home improvements are tax deductible or offer other tax benefits. For example, if you make green improvements to your home, such as installing a heat pump or solar panels, you may qualify for a tax credit. You may also deduct the cost of home improvements you make to improve the accessibility of your home or to allow yourself or another resident to age in place.

Home additions cost between $22,000 and $84,000, with the average addition totaling $51,000. Project costs can vary greatly depending on the type of addition and the required work to complete it. Homeowners can expect to pay between $80 and $210 per square foot for an addition. Conversions of existing space will sit toward the lower end of that range, while bump-outs and new construction add-ons will push toward the higher end.

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.

You can’t add home addition costs to an existing mortgage, but you can include them in a new mortgage if you take out a rehab loan. Rehab loans—FHA-backed 203k loans and conventional rehab loans—are for more than the value of a property, and the excess is meant to cover the cost of a renovation or home addition.

A guest house is not a bump-out addition. A bump-out addition is a small home addition built onto a preexisting room of your house, like a bay window or walk-in closet. While you can do a bump-out addition to a constructed guest house, a guest is not a bump-out addition. Other common bump-out additions are extra living room seating, space for a bathtub in a bathroom, and extra cupboard space in a kitchen.
