Anyone looking to expand an existing room with a new building must be aware of the fact that there is no natural light in the area. The situation will determine how severe this problem is. 

If the original room is located at the corner of a house with two windows on either side, there will still be natural light from the extension if it covers only one of those external walls. If you want to get more information about kitchen extensions, you can browse the web.

In many cases, however, the window that remains may not let much light in. This is especially true if it is located at the side of a building or overshadowed by a neighboring structure. This scenario calls for the designer to incorporate a large amount of glazing into the extension in order to reduce the loss of natural sunlight.

"Traditional” pitched-roof extension

A regular brick-built extension combined with a pitched roof that incorporates one or more roof windows is the best option for many architects and clients. These extensions will often have a vaulted ceiling that gives the space a spacious and open feel.

Although this room is very impressive inside, it can look unnatural and unfinished on the outside. It is difficult to find enough space for the roof to fit below the upstairs windows. 

Flat-roof Extension

Flat roofs can be used to solve the problem of restricted height. These extensions are relatively cost-effective, but they are not popular due to the lack of aesthetic appeal and potential technical issues such as leaks.

If the roof is constructed correctly, this should not be a problem. However, it is very rare for flat roof extensions to have any visual appeal. The low ceiling will also not help with natural light.
