More often than not, you can convert a conservatory into an extension, but in regards to the extent of the work, there are many factors to consider. These factors include the existing foundations, walls, roof, insulation and overall condition.
A comprehensive survey can establish just how much can safely be retained. Depending on the outcome of the survey, the options can be upgrading the existing conservatory, partially rebuilding key elements or replacing completely.
What’s the Difference Between a Conservatory and an Extension?
A conservatory and an extension differ mainly in their design, construction and thermal performance.
Conservatories usually have more glazing, including large windows and glazed roofs, while extensions tend to feature more solid walls and insulated roofing. This generally makes an extension better suited to maintaining a comfortable temperature throughout the year.
Extensions are also designed to blend more naturally with the existing property, creating a more permanent living space. Depending on the design and location, planning permission may be required.
Building Regulations can also apply to ensure that the building process and eventual structure meet requirements for safety, insulation and energy efficiency.
What Are Your Options for Converting a Conservatory?
Upgrade Your Existing Conservatory
In projects where the existing structure is in good condition, upgrading it may be a solution. Said improvements can include replacing glazing, adding insulation, installing a more suitable roof and updating the heating and flooring. The structure’s overall condition will determine what work is possible.
Partially Rebuild the Conservatory
A partial rebuild involves keeping the parts of the conservatory that remain suitable while replacing elements that need improvement. This might include installing insulated walls, fitting a new roof and upgrading windows and doors. The existing foundations also must be capable of supporting the proposed changes.
Replace the Conservatory With an Extension
For the greatest flexibility around design and features, removing the existing conservatory and replacing it with a tailored extension can be the way forward. Although typically costing more, this method allows for changes to size and layout, implementation of insulation, glazing options and more.
Can You Use the Existing Conservatory Foundations?
In certain cases, the foundations that are beneath a conservatory can be retained when converting it into an extension. Their condition, depth, width and construction will need to be checked to establish whether they can support the proposed structure. Ground conditions should also be considered as an extension may place greater loads on the foundations through heavier walls and roofing.
A structural assessment will be required to determine whether the existing foundations are adequate. Building Control may require evidence that they meet current requirements. Where the foundations are unsuitable or insufficient for the proposed work, they may need strengthening or replacing before construction can begin.
Can You Just Replace a Conservatory Roof Instead?
Absolutely, simply replacing the roof of a conservatory can greatly improve your space without the need for requiring a full conversion. A solid or tiled roof can provide far better insulation and maintain a comfortable temperature throughout the year
Before installation, the existing frames, walls and foundations should be checked to ensure they can support the additional weight. Building Regulations may also apply and while a new roof can improve comfort and energy efficiency, it will not turn a conservatory into an extension on its own.
Do You Need Planning Permission to Convert a Conservatory Into an Extension?
Planning permission is not always required when converting a conservatory if the work falls within permitted development rights with local authorities. Key aspects include the size of the extension, height and position. Previous extensions or alterations may affect what is allowed. Listed properties and homes in conservation areas can also face additional restrictions. Local planning policies may introduce further requirements and should be checked prior to work starting.
What Building Regulations Apply?
Building Regulations can apply to several aspects of a conservatory conversion, including foundations, structural strength and insulation and thermal performance. New windows and glazing must adhere to all current standards and ventilation. Any electrical installation should also follow any relevant regulations and meet all fire safety rules. Building Control approval may also be necessary after work is complete to check that it meets required standards.
How Much Does It Cost to Convert a Conservatory Into an Extension?
The price of converting a conservatory depends on the scale of the work and the condition of the existing structure.
Retaining and upgrading the current conservatory will generally involve less work than a partial rebuild or complete replacement.
Costs can include foundation improvements, structural alterations, roofing, windows and doors.
Insulation, heating, electrical work, flooring and internal finishes will also contribute to the overall budget.
The size of the existing conservatory and the amount of work required can have a significant impact. Design, planning and Building Regulations costs should also be factored into the project from the outset.
Is It Better to Convert Your Conservatory or Build a New Extension?
Upgrading Your Conservatory
Upgrading can work well if the existing structure is in good condition and the current size and layout already meet your needs. Improvements to the roof, glazing and insulation can help resolve temperature issues while keeping costs lower than a complete rebuild.
Replacing It With an Extension
Replacing the whole conservatory with an extension provides greater flexibility and scope for layout changes to create a space that better suits your home and future plans. New insulated walls can improve efficiency while allowing greater integration.
What Are the Benefits of Converting a Conservatory Into an Extension?
Converting a conservatory can provide a more comfortable and versatile living area for everyday use. Better insulation can help regulate temperatures throughout the year while new roofing, windows and doors can improve efficiency.
The project may also allow you to change the layout and create a stronger connection with the rest of the property. A well-designed conversion could potentially enhance property value for if or when you look to sell.
Is Converting Your Conservatory Worth It?
Can you convert a conservatory into an extension? Absolutely, is it worth it? That all depends on numerous factors. The age, insulation levels, how often you use it and the overall condition of the structure itself. Think about how you want the room to function and how much of the existing structure can be retained. Comparing conversion costs with a complete replacement is important, particularly if you have long-term plans to stay in the property.
FAQs
Can you turn an existing conservatory into an extension?
Yes, depending on the existing structure and whether the foundations themselves are suitable. You may be able to upgrade the conservatory, partially rebuild it or replace certain significant elements to achieve a suitable extension.
Can I replace my conservatory roof with a solid roof?
A solid roof may be possible if the existing frames and foundations can support the additional weight being implemented. The proposed roof must be built in line with relevant Building Regulations, including requirements for structure, ventilation and insulation.
Do I need planning permission to convert my conservatory?
Planning permission is not required on every development, particularly where development rights apply. But it should be remembered that depending on property type, location, extension plans and extension history can all change the need for permission.
Is it cheaper to convert a conservatory or build an extension?
Converting a conservatory can be cheaper when much of the existing structure is suitable for retention. However, extensive structural work can increase costs, making a partial rebuild or complete replacement more comparable to a new extension.
