Victorian House Extension


Copleston Road in East Dulwich offers a unique blend of suburban tranquility and convenient access to South East London. Nestled among picturesque tree-lined streets and grand villas, this neighborhood provides an idyllic, leafy environment. Just a short 18-minute commute from the bustling London Bridge. In this Victorian House extension architectural project, we undertook the refurbishment, extension, and transformation of a Victorian townhouse. The project spanned three floors and included a remarkable large bay window addition on the rear facade.

Extension Design

Our primary focus was on the ground floor, and in close collaboration with the client, we defined a comprehensive design brief. The goal was to seamlessly integrate modern functionalities while preserving the timeless charm of the original structure. Our architectural team carefully developed proposals for a new side and rear extension.  Thoughtfully considering internal reconfigurations to ensure a harmonious and sympathetic relationship with the historic building’s period features.


Through a meticulous examination of the site and existing floorplans.  We explored various concepts that prioritized functionality, form, and spatial flow. Rather than opting for a conventional large-scale extension.  We took an innovative approach by incorporating a stepped glazed facade into the rear elevation. This design choice created a visually intriguing architectural form.  It also allowed for captivating plays of natural light to permeate the interior, transforming the space into an inviting sanctuary.

Retaining Architectural Features

Preserving the integrity of the original structure was of utmost importance. Moreover, we carefully retained the reception area and restored the magnificent folding timber doors, ensuring a seamless transition into the library. This versatile space can be completely secluded, thanks to the folding doors and a concealed large pocket door hidden behind the bookshelves. Consequently, it offers moments of peace and tranquility amidst the busyness of daily life.

Shaker Panel Kitchen Extension

Emphasizing the architectural drama of the property, we introduced a split floor level that gracefully divides the front and rear areas. This clever design element not only adds intrigue but also invites exploration by offering tantalizing glimpses of additional spaces. As one moves through the split level, attention is drawn to the shaker panel kitchen, adorned with large structural glass panels that frame breathtaking views of the lush garden. The kitchen extension required meticulous planning due to the complex steelwork involved in supporting the existing bay window, fireplaces, and walls. The exposed steel beam serves as a striking contrast against the pristine white walls and ceiling, creating a captivating interplay of materials.

Increasing Natural Light

To enhance the luminosity and ventilation of the kitchen extension, we incorporated electronically operated Velux windows. These windows can be programmed to open when the room reaches a certain temperature and close automatically when rain is detected. We struck a perfect balance between modern aesthetics and the timeless allure of the period features in the interior styling. Additionally, we meticulously preserved and highlighted the original elements of the Victorian dwelling. By seamlessly integrating sympathetic paneling and decor, we achieved a warm and inviting colour palette, material selection, and finishes.


We gave special care and attention to lighting design, enabling us to create a customized ambiance. From mood lighting for intimate gatherings to task lighting for functional areas, in addition to ambient lighting that accentuates the architectural nuances, we thoughtfully considered and executed every aspect with precision.


Copleston Road holds a special place among our most cherished projects as it represents a meticulous refurbishment, extension, and transformation of a Victorian townhouse. Furthermore, the exemplary workmanship, unwavering attention to detail, and the sublime early evening light, beautifully captured by our talented photographer, greatly contributed to its distinction. Notably, the secluded library provides a serene retreat within the house, while the sweeping views of the garden enhance its appeal. Additionally, the concealed remote-controlled access panel in the kitchen’s wall paneling, revealing a discreetly hidden flat-screen TV, exemplifies the extraordinary level of craftsmanship and the exquisite finish we achieved.
