How do you make a cellar liveable?

How do you make a cellar liveable?

Transforming a cellar into a liveable space can be a fantastic way to add value and living space to your home. However, before you start picking out paint colors and furniture, there are some important steps you need to take to make your cellar a habitable space.

The first and most critical step is to ensure that your cellar is completely dry. Dampness and moisture can make your cellar uncomfortable and unhealthy to live in. This is where tanking comes in. By using a tanking system, you can create a waterproof barrier that prevents water from penetrating your cellar walls and floors.

Tanking slurry is a popular method for this, and it forms an impermeable waterproofing coating to protect your cellar.

Once your cellar is dry, you can start to think about how to make it comfortable and liveable. Proper ventilation is key to keep the air fresh and prevent any musty smells. You may also need to install heating or cooling systems to regulate the temperature, depending on your climate.

Lighting is another important consideration. Basements and cellars can be naturally dark spaces, so adding adequate lighting can help make the area feel bright and inviting. Finally, you’ll want to choose appropriate flooring and finishes that can withstand the sometimes harsher conditions of a below-ground living space.

With the right preparation and finishes, a cellar can be transformed into a comfortable, inviting space that adds value to your home.

You’ll need to consider factors like structural engineering, waterproofing, insulation, heating, and lighting to make sure your new living space is comfortable and safe.

Why do older houses have cellars?

Why do older houses have cellars?

Older houses were often built with cellars as they provided a practical solution to the problem of limited living space in smaller homes. In the past, people would have to find creative ways to store their belongings and food supplies, and a cellar was an ideal place to store items that needed to be kept cool or dry.

Additionally, cellars were often used as a workspace for tradespeople, such as blacksmiths, who needed a cool, dark place to work with materials like iron and steel. Over time, as living standards changed, people began to realize that their cellars could be converted into livable spaces, and the idea of the basement as a functional and comfortable part of the home was born.

Today, many homeowners are still drawn to the charm and history of older properties and the unique opportunities that cellars and basements can offer for adding value and living space to their homes.
