Kitchens, bathrooms and bedrooms are typically the rooms in any home that get the most use, which could also be why homeowners, when surveyed, consistently cited those rooms as the ones they most want to renovate.

It makes perfect sense to upgrade the rooms where you spend the most time, but in high-traffic areas you can’t afford to make changes just for the sake of cosmetics. You want improvements that can enhance your enjoyment of a room and its functionality.

Here are five smart improvements to make in the rooms users of Ranker.com voted as the most popular ones in their homes: kitchens, living rooms, bedrooms, bathrooms and game rooms.

Add natural light.

Most rooms in the home look better and are more functional in natural light, and more daylight can help reduce the need for artificial light. What’s more, there’s no arguing the positive mental and physical health effects of natural light. Daylight stimulates the body to produce Vitamin D and boosts brain levels of serotonin, which is thought to be associated with positive moods.

Adding skylights is a practical, cost-effective and attractive way to bring more natural light into virtually any room. Remote-controlled, solar-powered fresh-air skylights provide not just natural light, but passive ventilation, a real plus in kitchens and baths. Adding solar powered blinds, in designer colors and patterns, increases energy efficiency while giving you total control over the amount of sunlight entering a room through the skylight.

In kitchens, Energy Star-qualified fresh air skylights increase natural light and ventilation without requiring any loss of wall space you could better use for cabinetry. In bathrooms, they provide the perfect combination of privacy and healthful natural light and ventilation.

Add organisation/storage.

Clutter and chaos not only make a room function less efficient – it can impact your mood as well. Adding organisation and storage to rooms where clutter typically collects – such as bedrooms, living rooms and game rooms – is an easy, cost-effective way to improve the function of the room and how you feel about spending time in it.

In bedrooms, maximise closet space by installing organisation units. A variety of manufacturers offer ready-made units you can install yourself. Or, for a bit more investment, you can have a professional closet organiser custom-make a unit to fit your space and needs. In living rooms and game rooms, built-in shelving and cabinetry is a functional and beautiful way to improve organisation.

Improve ventilation.

Air flow is critical to the health of your home and everyone who lives in it. Ventilation in kitchens and bathrooms carries away excess moisture that can cause mold and mildew, and creates a fresher, more healthful environment by exhausting stale indoor air.

Bathrooms should be equipped with exhaust fans, and kitchen hoods should vent to the exterior of your home whenever possible.

Replace older, inefficient fixtures and appliances.

Fixtures and appliances are key elements of kitchens and bathrooms. Older ones not only look dated and shabby, they can cost you money because they use more electricity and water than newer, more efficient models.

Replacing old faucets, shower heads, dishwashers and washing machines with newer models that use less water can reduce your water bill and give kitchens and bathrooms a whole new look. Energy Star-qualified appliances such as stoves, clothes dryers, refrigerators and washers also use less electricity than older appliances, so you can also lower your energy bills.

Freshen the foundations.

Every room benefits from a good foundation, and that doesn’t just mean sturdy flooring. Wall color, flooring materials and trim are fundamental elements in any room. Simply repainting walls and woodwork can completely change the way any room looks. Or, if you like the colors you have, a fresh coat in the same color will make the room look brighter and newer. Replacing worn carpeting or dated tiles, or refinishing a hardwood floor are also great ways to improve the foundations of any room.
