Thinking about adding an orangery extension to your home? Whether you're aiming to brighten your living space, extend your kitchen, or create a seamless link to your garden, an orangery is a stylish and practical way to upgrade your property. At Draw Plans, we create professional orangery extension plans for homes across Greater London from just £795 + VAT.

In this article, we’ll explore everything you need to know about orangery extensions, including layout tips, cost estimates, and expert advice to make your project a success.

​

What Is an Orangery Extension?

An orangery is a hybrid between a traditional extension and a conservatory. It features solid walls, a brick or rendered base, and a partially glazed roof with a roof lantern or skylight at its centre. Orangeries provide excellent insulation, year-round usability, and bring in plenty of natural light without the excessive heat of a conservatory.

​

Orangery extensions are ideal for:

• Creating a bright, open-plan kitchen diner

• Extending a lounge or living space

• Building a stylish garden room or office

​

Benefits of an Orangery Extension

• Year-Round Comfort: Better thermal performance than conservatories

• Light-Filled Space: Roof lanterns and large windows bring in natural light

• Elegant Design: Adds a touch of luxury and architectural interest

• Adds Value: A well-designed orangery can significantly boost property value

​

Orangery Extension Costs in Greater London

Costs for an orangery extension vary depending on size, materials, and complexity, but here’s a rough breakdown:

Orangery Kitchen Extensions

Orangeries make a stunning addition to kitchens, creating a sociable, light-filled area perfect for family life or entertaining. Popular features include:

​

• Large roof lantern above the kitchen island or dining table

• Bi-fold or French doors opening to the garden

• Underfloor heating for comfort

• Modern or traditional glazed frames to match your home

​

Layout Tips for Orangery Kitchens:

• Zone the space with an island or peninsula

• Use consistent flooring throughout for flow

• Keep tall units to one side to maintain openness

​

Planning Your Orangery Extension: What to Consider

​

1. Planning Permission

Orangery extensions can often be built under permitted development rights, but not always. We assess every project individually and can submit a planning application if required.

​

2. Building Regulations

All orangeries need to comply with UK Building Regulations. We provide detailed technical drawings to ensure your build meets all requirements.

​

3. Orientation & Light

South-facing orangeries benefit from maximum daylight, but shading and ventilation should be considered.

​

4. Blending with Existing Property

Match brickwork, windows, and roof materials to complement your existing home.

​

5. Heating & Ventilation

Underfloor heating, opening windows and roof vents can help maintain comfort year-round.
