When extending your home, one of the primary concerns is the cost involved. Adding an orangery or conservatory increases your property's value and enhances your living space.
If you're exploring the costs associated with building a glazed extension, you've come to the right place. In this article, we will discuss factors that influence the cost of an oak orangery or conservatory while focusing on Hallmark Glazed Extensions as your trusted partner.
When planning a new glazed extension for your home or business, you might find articles published by industry magazines or online sources that promise alluring prices and seemingly straightforward solutions.
However, it's essential to approach such information with caution. While these articles may provide some general insights, they often present misleading prices and overlook critical factors that should be considered in the planning process.
As a result, your glazed extension project's actual costs and requirements can vary significantly, making it necessary to seek comprehensive and accurate guidance from trusted professionals.
We will go into further detail about the importance of considering all factors and consulting experts to ensure that your glazed extension journey is guided by accurate and helpful information.

Determining the Cost of an Oak Orangery or Conservatory
The cost of a glazed extension can vary significantly, with online calculators and estimates quoting figures ranging from £2500 to £5000 per square metre.
Such a wide variation can make it challenging to establish a realistic budget. As a rough estimate, a quality glass extension project usually costs around £3,400 per square metre of new external area.
For instance, a 30m² oak orangery-style kitchen extension, including building work to meet building regulations standards, lighting, underfloor heating, flooring, and professional fees, may be estimated between £3,500 and £4,000 plus VAT at 20%.
It's important to note that while other types of extensions, such as those made from hardwood, aluminium, or PVC, may be less expensive, the costs associated with building work, roofing, glass, and professional fees remain relatively constant.
Smaller orangeries under 18-20 m² tend to have disproportionately higher costs.
Considering Key Factors for Budgeting
As a homeowner, several key considerations will help you gauge an accurate budget for your glazed extension. Here are some factors to keep in mind:
Size
Determine the purpose of your glazed extension, whether it's a kitchen extension, dining room, family room, or lounge area.
Visualise the dimensions of the space and how it will accommodate your furniture and appliances.
Hallmark Glazed Extensions can provide images of previous projects to help you visualise the floor space required.

Planning Permission
Sometimes, you may not require planning permission for your extension if it meets specific criteria. Understanding permitted development regulations and restrictions can save you time and money.
Hallmark Glazed Extensions can guide you through the planning process and handle any necessary applications on your behalf.
Internal and Exterior Design
Consider the practical requirements of your glazed extension. Plan the interior finish, flooring, appliances, plumbing, heating, and lighting.
Explore the exterior design options that suit your property's aesthetics, materials, and finish. Hallmark Glazed Extensions offers bespoke design options.
Listed Buildings
Additional considerations and approvals may be required if your property falls under "Listed Developments," Conservation Areas, or Areas of Outstanding Natural Beauty (AONB).
Hallmark Glazed Extensions has extensive experience working with such properties and can assist with the design, planning application, and construction process.

Glazing Specifications
Choosing glazing and ventilation is crucial in making your glazed extension suitable for year-round use. Premium glazing specifications can provide excellent solar control and thermal insulation.
While such options may be initially considered costlier, instead, they should be considered an investment that ensures a comfortable living environment throughout the year.
By considering these factors and consulting with the expert design team at Hallmark Glazed Extensions, you can obtain an honest and accurate indication of the financial investment required for your specific oak orangery, conservatory, or tiled roof garden room.
The Value of Paying Design Fees for a Conservatory Project
As you dive into the planning process, you must recognise the value of hiring a specialist conservatory company and investing in design fees.
