Factors to Consider When Choosing Between an Orangery and Extension

  1. Before comparing the costs of an orangery and an extension, it’s important to understand the factors that can affect the overall cost of each option. Here are some factors to consider when choosing between an orangery and extension:
  1. Purpose of the Structure: While picking between an orangery and an expansion, the structure’s function is a vital factor. An extension is the greatest solution if you need more living space for a new bedroom, bathroom, or kitchen. An orangery is the finest option whether you want to enjoy your garden or utilise it as a home office.
  1. Size of the Structure: Another significant thing to consider is the structure’s size. The bigger the expense, the larger the structure. Orangeries tend to be smaller than extensions, but they can still provide adequate room for your requirements.
  1. Type of Material Used: The material selected might also have an impact on the total cost. Orangeries are normally constructed of uPVC, aluminium, or wood, although expansions can be constructed of a larger range of materials, including brick, stone, and wood. The choice of material will rely on the overall design of your home, the purpose of the building, and your budget.
  1. Location and Site Preparation: The location and site preparation can also affect the cost of the structure. If the site is uneven, then additional work will be required to level the ground. Orangeries tend to require less site preparation than extensions.
  1. Planning Permission and Building Regulations: While building an orangery or an addition, planning authorization and construction rules must be taken into account. All solutions will necessitate planning clearance, although the criteria will range depending on the size and form of the construction. Building codes must also be observed to guarantee that the construction is safe and fulfils the required requirements.
  1. Labour Costs: The overall cost of the building will be significantly influenced by labour expenses. The amount of labour required will vary depending on the project’s size, complexity, and location.
