Working out whether to go for an extension or a conservatory can be tricky. They both give you extra space at home, but in different ways and with different costs. If you’re stuck deciding between these two options, you’re not alone, it’s one of the most common questions we get asked.
We’ve helped countless homeowners across Birmingham, Wolverhampton, and the West Midlands expand their homes, so we understand the factors that might sway your decision one way or the other.
We’ve written this guide to walk you through the differences between each option to help you figure out which one suits your needs best. We’ll cover styles, costs, planning permission and more.
What is a Conservatory?
A conservatory is a structured room that connects to your house, typically with glass walls and a glass or polycarbonate roof. Conservatories bring natural light into your home while giving you extra living space. Our conservatories come in a range of styles, including Victorian, Edwardian, lean-to, and bespoke designs.
What is an Extension?
An extension is a permanent addition built using similar materials to your house. Extensions can be single storey or double storey and can be used for almost any purpose, from kitchen extensions to extra bedrooms. They feel like a natural part of your home rather than a separate space.
Key Differences Between Extensions and Conservatories
Structure and Materials
Conservatories are mainly built with glass panels and frames, which gives them their light, airy feel. In modern times, incorporating a roof lantern has become popular, offering even more natural light and a stylish feature.
Extensions are made with the same building materials as your house. They have proper foundations, brick or block walls, and a conventional roof that matches your existing property. This makes them feel and look like a more permanent addition.
Planning Permission and Building Regulations
Conservatories often fall under ‘permitted development rights’ in the UK, meaning you don’t need planning permission if they meet certain conditions (like being under a certain size and away from boundaries). They also have more relaxed building regulations if it’s separated from your home by external doors and has its own heating controls.
Extensions typically need to comply with full building regulations approval. Single storey extensions might fall under permitted development rights, but larger projects usually require planning permission.
At West Midlands Home Improvements, we are experts in building regulations and planning permission. We can handle all applications for you, so you don’t have to worry about complicated rules and processes.
Temperature Control and Energy Efficiency
Modern conservatories have improved insulation compared to older models, making them more comfortable year-round. With efficient glazing and a high quality roof, you can avoid common issues like the greenhouse effect (where a conservatory overheats during the summer).
Extensions have the same insulation as the rest of your house, making them usable all year round. They usually use the same heating system as your home and are typically more energy efficient than a conservatory, which can save on heating bills in the long run.
Cost Considerations
Conservatories are generally more budget-friendly to build than extensions. This makes them an excellent option for adding extra living space without a higher investment.
Extensions require more extensive building work, which affects the overall cost. However, they often increase the value of your home more than conservatories, offsetting at least some of the initial investment.
Why Choose a Conservatory?
A conservatory brings abundant natural light into your home, creating a bright space that connects with your garden. For many homeowners, conservatories offer a peaceful retreat within the house, a place to relax with a book, entertain friends, or simply enjoy outdoor views while being protected from the weather.
They’re typically quicker to build than extensions, and the building process is generally less invasive since most of the work happens outside your main living areas. Conservatories also tend to be cheaper than extensions, giving you additional living space without the higher investment. Many conservatories fall under permitted development rights, which can simplify the approval process.
If you’re looking to add a bright space for relaxing, reading, or enjoying the garden views, rather than a fully integrated living area, a conservatory could be the ideal choice.
However, if you desire a bigger space that looks like a natural extension of your house or want to add a new bedroom, you might find an extension better meets your needs.
Why Choose an Extension?
Extensions provide a versatile, fully-integrated living space that you can use for virtually any purpose. Whether you need a new bedroom, an expanded kitchen, a dining area, or a home office, an extension delivers practical space that functions just like the rest of your house.
Extensions offer a practical solution for families who need extra room for growing children or want to avoid the stress and cost of moving to a larger home. The great thing about extensions is their versatility; they can be designed to serve multiple purposes or adapt to your changing needs over time. A space that starts as a home office could later become a dining room or a new bedroom.
Extensions typically add more value to your property than conservatories, making them a sound long-term investment. While extensions do require a higher initial investment than conservatories and involve more extensive building work, the result is a durable, energy-efficient space that truly expands your home.
If budget is a primary concern or you’re specifically looking for a light-filled room with garden views, a conservatory might be more suitable for your needs.
