New Dwellings
At some point, most of us have imagined
our ideal home - the one we’d build if we
could start from scratch, designed entirely
around our tastes, habits and priorities.
For many people, those ideas never go
much further than idle daydreams sparked
by an episode of Grand Designs. For others,
they become something real.
This guide walks you through the entire
journey, from first decision to first key turn.
This is how you transform self-build
fantasies into oak, brick, timber, steel and
glass.
Why Choose an Oak Frame
Conservatory?
Whether you're
updating an old
uPVC conservatory
or exploring new
extension ideas, an
oak frame
conservatory is a
versatile option that
complements both
traditional and
modern homes. Like any home extension, various factors must be considered,
from design aesthetics to building regulations.
We’ll walk you through the different styles, materials, and finishes available, as
well as important planning considerations, so you can create the perfect oak
frame
conservatory for your needs.
Conservatories are usually best suited to north facing elevations as heat build
up can be excessive in the hottest of summer months.
What Defines an Oak Frame
Conservatory?
A conservatory is traditionally defined as having at least 75% of its roof and
50% of its walls glazed. However, modern trends are shifting away from this
format due to
energy efficiency concerns.
An oak frame conservatory is generally designed as a single-purpose room,
often used as a living space, sitting room, or dining area, with large glazed
sections that
offer scenic outdoor views.
This contrasts with other oak frame extensions, such as garden rooms or
orangeries, which may serve multiple functions like combining a kitchen and
dining area.
Comparing Oak Frame Extensions:
Conservatory, Orangery, or Garden
Room?
•
Orangeries:
These feature a flat
or mansard roof
with a glazed
lantern and were
originally designed
in 17th-century Italy
to house tropical
plants. They offer a
luxurious feel, with
windows rather than fully glazed walls.
•
Garden Rooms:
Typically built with solid roofs and large windows, these extensions blend
seamlessly with the existing house and can incorporate dramatic glazed gables
for an elegant touch.
Planning Permission & Building
Regulations
Like any home extension, an oak frame conservatory must comply with
planning laws. If you live in a Conservation Area, you’ll need planning consent.
However, under Permitted Development (PD) rights, you may not require
formal permission if your conservatory:
•
Is no larger than 50% of the total land around the original house
•
Does not exceed 4 meters in height
•
Does not extend beyond the principal elevation existing house wall -
usually the front wall of your property.
Building regulations may also be required, especially if your conservatory is
over 30sqm, or if it alters the existing structure, such as removing an external
wall.
Design & Build Process
Oak frame
conservatories offer
flexibility in design,
from minimalist
contemporary styles
to traditional
aesthetics featuring
dragon tie beams
and direct oak
glazing. You can
choose from a variety of shapes, glazing options, and finishes to match your
home’s character.
Glazing Options
•
Bi-fold doors: Create seamless indoor-outdoor transitions
•
Face glazing: Provides a sleek, modern look while allowing for natural
movement of the oak frame
•
Infill glazing: Allows for opening lights for a nice through breeze in the
summer.
•
Direct glazing: Fixing glass direct to the rebated oak frame
•
Roof glazing: Adds extra light, with options like skylights or a partially solid
roof for temperature control
Structural Considerations
Oak frames use green oak, which naturally shrinks and moves over time.
Proper design calculations are essential to maintain structural integrity.
Extensions can be built to any size, though conservatories must meet glazing
percentage requirements.
Large spans (up to 6 meters) are achievable without central support posts,
creating a spacious and open layout.
Heating & Ventilation
Given the high level of glazing, heating and ventilation must be carefully
planned.
Options include:
•
Underfloor heating – Efficient and space-saving
•
Log-burning stoves – Adds character and warmth
•
Electric heaters – Flexible but can be costly to run
•
Roof vents & opening windows – Essential for temperature control and air
circulation
Costs & Budgeting
The cost of an oak frame conservatory varies based on materials, design
complexity, and finishes. On average, a high-quality oak frame extension costs
around £50,000, covering the oak frame, glazing, joinery, and roofing. We also
have a price configurator for garage buildings.
Tips for Cost Reduction:
•
Opt for simpler designs to minimize material and labour costs.
•
Reduce the amount of exposed oak to cut expenses.
•
Choose cost-effective glazing and roofing options.
•
Plan heating and ventilation solutions carefully to avoid costly
inefficiencies.
Pros & Cons of Oak Frame
Conservatories
Pros:
✔ Brings in natural light and creates a seamless indoor-outdoor connection
✔ Adds character with its warm, natural oak aesthetic
✔ More sustainable than uPVC, especially with FSC-certified timber
✔ Long-lasting – oak structures can stand for hundreds of years
✔ Excellent thermal performance compared to plastic or aluminium
Cons:
✖ More expensive than uPVC conservatories
✖ Requires periodic maintenance to retain its original oak colour
✖ Needs careful design planning to accommodate lighting and socket
placement
✖ Site access can be a challenge for large oak frame deliveries
Can You Build an Oak Frame
Conservatory Yourself?
For skilled DIYers, an oak conservatory can be built using pre-assembled kit
forms, provided by specialist suppliers. These kits include numbered
components and
assembly instructions for on-site construction. Albion Oak can supply in kit
form if required.
Choosing a Supplier
When selecting an oak frame conservatory supplier, consider:
•
Whether you need a kit or a fully bespoke design
•
Their range of standard designs vs. custom options
•
Additional services like planning and construction assistance
•
Experience and reputation in the industry
While oak remains the preferred choice for durability and aesthetics, other
timbers like Douglas fir, larch, or glulam can be used. These materials offer
different
moisture content properties and stability, with some being more cost-effective.
Maintenance & Longevity
•
Regularly clean gutters and downpipes to prevent damp issues.
•
Oak naturally weathers to a silvery hue but can be treated to retain its
original colour.
•
With proper care, an oak frame conservatory can last hundreds of years.
Final Thoughts
Adding a conservatory enhances your home’s living space while increasing
natural light and outdoor connectivity. If an oak frame doesn’t suit your needs,
consider
