As some homeowners resolve to, "stay put," they are seeking more simple and budget-friendly home renovations.

A Harvard study finds midsize kitchen and bath projects are driving the home renovation market, and consumers finding it hard to tap home equity loans because of tighter lending are opting to pay cash for lower-cost work.

Stephen Melman of the National Association of Home Builders says homeowners are also looking at not only the aesthetic, but also the insulation to improve energy efficiency, the accoustical insulation, as well as security. He says older homeowners are also going for more senior-friendly improvements such as grab bars around showers and bathubs that are more curved and lack sharp corners.

The, "big four"for home renovations right now are mid-size kitchen and bath projects, maintenance work and improving energy efficiency. But some of the improvements may be as simple as an interior or exterior paint job.

The Harvard study found Americans are now spending more on remodeling than they are on new construction.
