There are extensions of different kinds with different price tags. Some of the popular forms of house extensions include:

  • Side Return Extension: this is an extension of the side of the house that is normally common in terraced houses, this allows an extension of the home, and at the same time, it does not interfere with the garden.
  • Loft Conversion: One of the most economical methods of creating additional space with no loss of outdoor space, which is best suited to use in the attic to create an additional bedroom or working place.
  • Double Story Extension: This kind of extension will provide up-stairs and down-stairs space, which will greatly affect the cost and will provide a lot of space.

Materials Used
