Our approach to renovation design

Renovating an existing building presents unique opportunities and challenges. Our approach ensures that every project is carefully considered to achieve the best results for both the building and its inhabitants. Our process is guided by three key principles:

1. Respect for existing architecture

We carefully balance old and new, respecting the heritage and craftsmanship of existing buildings while enhancing their functionality and efficiency for modern living. Our approach ensures that period features are retained where appropriate, seamlessly integrating contemporary interventions.

2. Energy efficiency & sustainability

Older buildings often require significant improvements to their thermal performance. Our renovations focus on upgrading insulation, airtightness, and renewable energy integration while working with the building’s existing fabric to minimise environmental impact.

3. Enhancing liveability

Every renovation project is tailored to suit modern lifestyles. Whether it’s reconfiguring layouts, opening up spaces, or improving natural light and ventilation, our designs prioritise comfort, usability, and wellbeing.

Renovation projects in action: case studies

Project 1 – Boars Hill, Oxfordshire

A 1930’s home, in poor condition and with some unsympathetic additions, was purchased by our clients as a project. Their brief to us was to create a bright, friendly and sociable family home, whilst extending it to complement the existing architecture and improve the connection with the beautiful gardens and existing swimming pool.

Project 2 – Amersham, Buckinghamshire

A 1980s home, with small dark rooms, and virtually no connection to the lovely gardens and expansive views.  We worked closely with the Landscape Architect from the outset, to completely reimagine how the house, garden and views related to each other, and then looked at how the thermal performance and energy efficiency of the building could be improved. The final design involved removing the existing first floor and roof, introducing a new mass timber (Cross Laminated Timber, or CLT) first floor and roof structure, and then externally insulating and cladding the house in contemporary materials.

Project 3 – Islington, London

This extension and retrofit of an early Victorian terrace created a new rear extension, whilst also taking out the rear part of the ground floor to create a double height dining space, that opened up the basement into a bright and sociable kitchen. A new staircase was then inserted to link the living spaces below with the bedrooms above, climbing from the open plan kitchen through the double height dining room to the refurbished first and second floors.
