12 Townhouse Extension Ideas to inspire your project

2. Before & After: Rear Courtyard Transformation

This townhouse’s rear courtyard has been transformed with the addition of an orangery, creating a seamless indoor-outdoor living space perfect for hosting guests

3. Utilising boundary walls

This home extension greatly benefits the neighbouring boundary walls, the room extends each side beyond the orangery front and within the brick walls making the most of the available space.

4. Open plan kitchen extension

This orangery kitchen extension transformed what was once a dark, lower-level kitchen into a bright, open space perfect for family living. The client shared their full experience in the case study linked below:

5. Small Orangery Addition

Collaborating with design specialists Huntsmore, who managed the lower ground floor renovation, we created a space that enhances the Georgian townhouse’s grade II listed charm while ensuring comfort and usability for years to come.

6. Two-storey townhouse extension

Thoughtfully designed to maximise available space on a London townhouse, this project included a substantial rear garden excavation allowing for a multi-storey orangery. Upstairs, it serves as a charming dining room that opens onto a balcony, whilst the downstairs provides a spacious living and entertaining area.

7. Dual level London Townhouse Orangery

Our client’s challenging site inspired a creative two-level glazed extension. The design process focused on creating a functional layout that complemented the existing rooms. The final structure features a light-filled lower ground space off the kitchen, perfect for entertaining, with a glazed room above offering beautiful garden views.

11. Townhouse conservatory with decorative gable

This London property was extended with a conservatory that featured a decorative gable. An additional roof lantern was also added to the existing structure to allow more light into the home.

12. Using Bronze for your home extension

While not every homeowner desires a conservatory or orangery to extend their home, an alternative is to opt for a solid structure with elegant metal windows. Our sister company, Architectural Bronze Casements, specialises in designing and crafting bespoke windows, often specified for such projects. See a selection of completed projects on townhouses below.
