A Warm, Light and Airy Space

Aesthetically similar to a Mediterranean sunroom, the Lean-To Conservatory is ideal for those who prefer a subtler look – it’s clean lines and structure complementing your property, rather than overshadowing it.


A lean-to conservatory is typically a rectangular or square shape. The rectangular shaped lean-to conservatory has the longer side running along the back of the property.

A flat angled roof slopes downward, allowing rain to run off the roof. This is what gives this conservatory style the appearance of ‘leaning’ against a house which is how it the lean-to conservatory gets its name.

Tailored For You

As a very popular Conservatory option, this classic conservatory style can be tailored to suit your personal tastes, and is available in a wide range of colours, styles and finishes.


You can choose from smooth finished surfaces or wood grain effects for a more traditional look. You will also have the option of either full glass to the sides, part brickwork (dwarf walls) and UPVC infill panels.

A Choice of Lean-to Conservatory Styles

UPVC lean-to conservatories come in many in variations. Options for the base of the conservatory include dwarf walls, fully height glass panels and UPVC panels.

UPVC panels are normally the most affordable options however, dwarf walls provide a greater level of privacy, security and efficiency.

The base and roof offer great versatility. This flexibility makes them highly desirable amongst home owners and buyers alike.The main parts of a lean-to conservatory which offer the most versatility in terms of design are the base, roof and ventilation.

Standard Lean-To Conservatory

Standard lean-to conservatories have dwarf walls with double glazing on all three sides, as well as either a glazed or tiled roof.


Suitable For Any Property

Ideal for houses restricted by height, the Lean-To’s low pitched roof can be accommodated for awkward spaces, making it the perfect choice for bungalows or terraced properties.

This small conservatory will not restrict any space at the side of the house. Those with Victorian or Edwardian terraced homes can create a long and narrow lean-to style which extends beautifully into the garden.

As a very versatile conservatory option, the Lean-To can be used as greenhouse, dining room or lounge, and with the current advancements in technology, features such as double glazing and floor heating are also readily available.

Wood, Aluminium or UPVC Lean- To Conservatories?

When it comes to choosing the material for your conservatory, you will be given a choice of either wood, aluminium or UPVC.


Hardwood frames are used in more traditional properties,especially those that are situated within conservation areas. Many people choose wood for its classic appearance but a wooden conservatory is not as durable as an aluminium or UPVC conservatory.

The Cost Differences

Aluminium is more expensive to manufacture than UPVC. Due to it’s affordability, UPVC has led the way for replacement windows and doors, as well as conservatories.

In terms of durability, aluminium conservatories have a longer shelf life as UPVC will eventually degrade over many years.

Lean-To Conservatory Roof

The roof is low pitched compared to other conservatory styles which have an apex roof design.

You have many options when it comes to kitting out your conservatory for killer efficiency.

  • Thermal glass can be used in sealed units to help maintain heat.
  • Under-floor heating to provide a consistent temperature – especially during colder periods.
  • Roof vents will aid air flow, preventing heat from building up in the summer.
  • Tinted glass can help reduce sun glare.
  • Although pricey, air conditioning is also an option if you want to keep your space cool during hotter months.
  • Conservatory blinds allow you to control the amount of light that enters your conservatory. This keeps your space cool in the summer, warmer in the winter and also provides greater privacy.

Lean-To Conservatory Planning Permission

As conservatories are seen as a ‘permitted development’, you are unlikely to require planning permission. A standard lean-to conservatory will be installed at the back of the house so it is extremely unlikely you will need any form of permission.

Planning PermissionPlanning Permission: Exceptions

There are of course, exceptions to the rule.

If your property is on designated land such as an Area of Outstanding Natural Beauty or a National Park and conservation area then you need to seek advice and permission from your local Building Regulations.

This also goes for any conservatory which is going to take up more than 50% of the property’s curtilage or if its placed in front of your house.

The best place to visit is the Government’s Planning Portal website which has all the up-to-date information on conservatory planning.

Lean-To Conservatory Installation

Lean-to conservatories are the most straightforward of conservatory styles to install. The installation of a lean-to conservatory should take a few weeks.

Make sure you agree to a timescale and schedule with your conservatory installation company beforehand. That way you will know when you can expect to have the installation finished.
