Difference between a Loft and a Mezzanine

The main difference between a Loft and a Mezzanine is that a loft is a habitable space created just under the roof and this Lofted room can be accessed by a ladder. There are various types and styles of lofts and sometimes it is possible to get a loft conversion without getting the planning permission as some styles are simple.

A mezzanine is an intermediate floor in a building and most of these have a partly open double-height ceiling floor and this does not usually extend all the through the other ends of the room. These mezzanines are semi-permanent structures and there is a lot of professional supervision required to install these.

What does a typical loft conversion schedule look like?

There are several measures involved in a loft conversion. Before buying all of the necessary materials and beginning the conversion, you should pay close attention to this process. Several factors are at play, and it is important to consider each one and be prepared for any eventuality. Most agencies stick to a strict schedule, and following it step by step will help them become more effective.

Inspection of roof space - Before you even get the idea of loft conversion and start making plans, it is important to know if your house supports a loft conversion. Some houses are too weak or they get weak over time because they are very old. The whole loft conversion is based on the structural integrity of the roof so the inspection of the roof takes place primarily and only if the roof is good, the other plans are made. If the roof is not strong enough, then the roof can be replaced.

An architect or surveyor confirms suitability - The next part involves determining if the house is suitable for a certain kind of loft conversion. You have many different types of a loft conversion like Hip-to-Gable loft conversion, Mansard loft conversion, Velux Loft conversion, Dormer Loft conversion, etc. You can select a style and the architect will then determine if the style is suitable for your house. Not all plans go with a house and the size of the food and the structural strength will determine the style. If your plans don't suit your house, then teh architect will suggest an alternate style.

Plans are made - Once the styles are conformed then the planning process begins, this where all the crucial work begins. A proper blueprint is made on how the loft conversion will be performed and all the details of the room will be laid out. If you are converting the loft into a bedroom you will plan on where you want the bathroom, where you'll have the bed, a television, and power outlets. This planning is the key because if the plans are wrong then the whole interior of the room gets messed up.

Getting the Permissions - If you are making changes to the roof or if you are extending the walls, you will have to get planning permission from the local planning authorities. These planning authorities will go through the blueprints or the plans and the details of the house and determine if the house is suitable for a loft conversion. A green light is only given if the house compliments a conversion. If the planning authorities find out that the conversion will compromise the structural integrity of the house, they will decline the permissions and you would have to either make new plans or give up on the conversion. This is why inspection is carried out in the first place, if you ignore inspection you will face problems later on.

The loft is cleared - If the plans are perfect and the permissions are in hand, then the whole idea of conversion can be converted into a reality. This is where all the manual work begins and before anything is changed, the whole loft is cleared. Some owners use the loft as a storeroom and store various items or they might have unused wooden logs or other materials that were used while constructing the house. These materials are removed from this space and the whole loft is cleared so that the architects can get a clear look at what is on the inside.

Rewiring is assessed - The next important step in this process is to assess the rewiring, if you want a perfect room it is important to have power sockets and it is essential to plan to rewire safely. There can be short circuits or fires caused by inefficient wrong so the whole rewiring plan is made beforehand to ensure safety and efficiency. It is also not possible to make provisions for power outlets after the conversion is done.

Floor insulation - Insulating the floor is important because the floor is pretty thin and there can be heat or coolness escaping through the roof. This is why it is important to insulate the floor to maintain the temperature. If the floor isn't insulated you might need high-powered heaters or air conditioners to keep the room hot or cold.

Wall reinforcement - To maintain the structural integrity, the walls are reinforced and this makes the house stronger. This is a mandatory step because normally, there is no need to reinforce the walls but as time passes the walls might become weak and if there is any natural calamity, the walls may collapse.

Rooflight Installation - Once all the work on the walls and the roof is completed, then the work on the windows begins. Having natural lighting inside the lifted room can be a great advantage and you can even install solar electricity generators on the roof. These windows allow natural light to enter the room and the natural light is a source of vitamin D and also kills harmful bacteria. The natural light also creates an aesthetic feel and gives a good exterior look.

Steps Installation - Once all the work on the room is completed, the work on how to access the room begins. Most of the loft conversions have a staircase and accessing the room via stairs can be easy. It is very hard to install a heavy-duty lift. There is a slight possibility of installing a small lift just to make the room a little fun. This small lift can be used to lift snacks and other small goodies from the floor to the room.

Interior Decoration - The whole process of loft conversion doesn't end with building the loft, the converted room is useless if it is not petty from the inside. We at loft conversion London make it our job to design the interior and suggest some good ideas. We have some of the best interior designers and they have helped in creating some of the most beautiful rooms.
