Collins Meadow, Harlow

The project sought to comprehensively modernise the existing dwelling through a carefully considered two-storey rear extension, a new entrance porch and the introduction of two dormer windows to the principal elevation, pushing the extent of what could reasonably achieve planning support.

The site presented a number of technical and contextual challenges, including a significant fall in levels towards the rear of the property. The design therefore required careful consideration of the existing topography, building proportions, roof form and relationship with the surrounding properties. Further complexity was introduced by the requirement for a sewer build-over application, which had to be coordinated alongside the proposed extension works.

The resulting proposals were developed to maximise the potential of the existing dwelling while creating a more contemporary, functional and cohesive home.

Whieldon Grange, Harlow

The homeowners had recently purchased the property and sought to maximise the available habitable floor area while making full use of the opportunities afforded by Permitted Development rights.

The proposals centred around a substantial single-storey rear extension, creating a generous open-plan kitchen and dining space designed to accommodate extended family gatherings and everyday family life. A new contemporary glazed entrance porch was also incorporated to enhance the arrival experience and improve the relationship between the existing dwelling and the proposed alterations.

Prior to commencing the works, a Lawful Development Certificate for Proposed Use was successfully secured, providing formal confirmation that the proposed works fell within the scope of Permitted Development rights and could proceed without the need for a full planning application.

Nafferton Rise

The Nafferton Rise project comprised a two-storey side extension designed to maximise the available space while responding sensitively to the existing site constraints. A key consideration was the close proximity of established trees to the proposed extension, requiring the design and foundation strategy to carefully safeguard the existing trees and minimise disturbance to their root protection areas.

The extension was constructed using traditional cavity wall construction, supporting a first-floor timber structure and pitched cut roof finished with matching tiles, ensuring the new addition remained sympathetic to the character and proportions of the existing dwelling.

Internally, the proposals created a substantial open-plan kitchen and dining space through the formation of a wide opening within the existing external wall. The opening was supported by a bespoke steel box frame, providing the necessary structural support while creating a strong connection between the original dwelling and the new extension.

To the rear, large bi-fold doors were introduced to maximise natural light, improve the connection with the garden and create a seamless relationship between the internal living space and the external environment.
