One of the most frequently asked questions we receive at Hallmark Glazed Extensions is, "What does a hardwood conservatory cost?".
The answer to this question is more complex than providing a fixed number because the cost of a hardwood conservatory extension depends on several factors.
In this comprehensive guide, we will explore the different aspects that influence the cost of a hardwood conservatory.
It's important to understand that while budgeting for your extension is crucial, investing in a modern oak conservatory, hardwood orangery, wooden garden room, or any timber-glazed extension will immediately increase the value of your home.
All the conservatories and glazed extensions we design and build are entirely bespoke, meaning no two wooden conservatories are the same.
As a result, the cost can vary significantly based on specific requirements.
What Type of Timber Conservatory Frame Material Should You Choose?
The choice of material for your glazed extension plays a vital role in determining your project's overall look, feel, and cost. Generally, three common materials are used in building extensions: uPVC, aluminium, and Oak.
uPVC Conservatories: uPVC conservatories are the most cost-effective and come in various frame sections, wood grain effects, and colours.
Some may refer to them as a 'timber alternative,' but this term can be misleading. Excluding building work costs, a good quality PVC conservatory will cost approximately half as much as a typical hardwood conservatory.
Aluminium Conservatories: These are more expensive than uPVC conservatories. The frames can be provided in nearly any colour and fall in pricing somewhere between PVC and hardwood conservatories.
Wooden Conservatories: Timber conservatories are generally the most expensive and come in various types and categories depending on the type of wood used.
Softwood is the least expensive option but has a shorter lifespan compared to hardwood.
Hardwood, on the other hand, is more durable and can last much longer. Some common hardwoods used include Sapele, Iroko, Idigbo, and Oak. Oak, which comes in different categories like Green Oak, Air Dried Oak, and Fully Seasoned Oak, is known for its quality, longevity and natural appearance.
You can consider materials like Idigbo or Sapele for a more budget-friendly painted hardwood option.
What Type of Glazed Extension Are You Looking For?
The type of extension you want will also impact the cost. You might be considering a conservatory, an orangery, or a tiled roof garden room; each has unique design and specification differences that affect the price.
It's crucial to understand these variations to make an informed decision.

What About Conservatory Glazing?
Nowadays, a conservatory or glazed extension is considered a proper living space, and ensuring it remains comfortable throughout the year is vital.
Understanding the impact of glazing on the extension's temperature is essential.
It's also worth noting that building regulations do not cover the efficiency of glass in an exempt building. So, choosing the correct glass specification is crucial, particularly for solar control and insulation.
a) Solar Control Glass: If your proposed extension is south or west-facing, solar control glass should be considered for both the roof and the vertical frames. The best roof glass can reflect up to 83% of the sun's heat, while clear solar control glass can reflect up to 58%.
b) Insulation Value: If you want the room to be efficient in keeping heat in during the winter, we recommend double-glazed roof glass with an insulation value of 1.0. This is significantly more efficient than single glazing and more so than most conservatory glass options currently available. Even north-facing frames can benefit from clear solar control glass with an insulation value of 1.0.
c) Triple Glazing: Despite the hype around triple glazing, it offers minimal insulation benefits compared to the additional cost. The added weight of the necessary overall unit thickness can be taxing on your timber frames, making it often not worth the extra expense.
In Conclusion
In conclusion, understanding the cost of a hardwood conservatory is not straightforward, and it's unlikely you'll be able to purchase one with suitable specifications for less than £50,000, unless it's being installed onto an existing base.
The best way to determine the actual cost is to have a free design and site consultation, discuss possibilities, and obtain a fully detailed proposal that caters to your specific requirements.
