Conservatory vs Extension: Which Should You Choose for Your Home?

When choosing between a conservatory or an extension, it can be difficult to determine the best choice for your space, or even know the difference between the two. 

We’ll explore the distinct characteristics, benefits and cost of each, helping you make the right decision for your home.

Characteristics of Conservatories and Extensions

Conservatories and extensions are two popular options for expanding living spaces. Conservatories are, traditionally, made of glass walls and glazed roofs where only the roof is insulated. 

From traditional Victorian and Edwardian designs, to modern minimalist styles, conservatories come in a variety of shapes and sizes. Their stunning features are designed to maximise natural light, creating a space that complements your home’s architecture and surroundings.

Extensions are commonly designed to be part of the existing property, and generally feature both insulated walls and roofs. They provide versatility in design, ranging from classic brick or stone exteriors to modern finishes, allowing for customisation to suit various home styles.

The Benefits: Conservatory vs Extension

Deciding between a conservatory or extension comes down to your requirements and long-term goals for your home. Understanding the advantages of each helps to determine if they match your needs. 

Conservatory Benefits:

1. Natural Light: Fills interiors with sunlight.

2. Connect with Nature: Provides a seamless blend of indoor-outdoor space.

3. Versatility: Conservatories can be tailored for your needs. Use the space as a dining room, home office, relaxation room, and more.

4. Adaptability with home design: Can be customised to match existing architecture and style.

5. Year-Round Enjoyment: Insulation ensures comfort throughout all seasons.

6. Property Value: Potential to enhance home appeal and increase market value.

Extension Benefits:

1. Increased Living Space: Create the space you need such as an extra bedroom, entertainment room, gym, kitchen, and more. 

2. Tailored Design: Customisable to blend with your home

3. Enhanced Functionality: Add rooms or expand existing areas.

4. Long-Term Investment: Can increase property value

Cost of Conservatory vs Extension

When it comes to maximising your living space, deciding between a conservatory or extension often comes down to cost. When reflecting on the price of each, here’s what to consider: 

  1. Size: The size of your conservatory or extension can impact the overall cost
  2. Materials: The choice of materials significantly impacts the overall cost. For conservatories, materials like uPVC, aluminium, or timber frames can vary in price. Similarly, extensions constructed with brick, timber, or glass materials will have different costs.  
  3. Design Complexity: Intricate designs or customisations, such as curved walls, bespoke windows, or intricate roofing can impact costs.
  4. Building Regulations: Local building regulations can influence costs. 
  5. Additional Features: Optional features such as heating, insulation, flooring, and electrical installations can add to the overall cost. 

Conservatories, usually, offer a budget-friendly alternative to extensions. This is because conservatories are typically an attachment to your home, and require fewer materials. 

Extensions tend to be more expensive due to their structural complexity and the need for solid walls and roofing, both often needing added insulation. The expense of an extension can also depend on whether it involves single or multiple stories. 

Planning permission can also impact costs greatly. If adding a completely new extension, planning permission costs can vary, depending on size and location.

Make the Right Choice for Your Home

When it comes to home improvements, choosing between adding a conservatory or extension simply comes down to your personal preference or needs. Assess how you use your home, if you’re looking to create a space to relax in natural light and comfort all year-round, a conservatory is the choice for you. If you’re looking to create additional functional space, an extension is the right choice for you. 

Ensure what you choose matches your vision and enhances your living experience.
