Harefield Road Modular Loft Conversion, Crouch End

Loft floor extension to create additional one bed flat above an end-of-terrace property in Crouch End.

Dormer extension to create an additional residential unit

This project was for the creation of an additional floor at second floor level of an end-of-terrace corner property in Crouch End, north London. 

The dormer extension is contemporary in style and takes full advantage of the westerly high-level views to the Highgate and Muswell Hill hills through glazed slots and sliding doors that provide access to a roof terrace with 360° views to the surrounding hills.

The new extension provides an additional one-bedroom flat, but with the flexibility to act as an extension to the first floor flat until such time as the owners decide to separate the two flats in accordance with their family’s needs.

The roof extension echoes the existing, older, first floor kitchen extension in its openness to the garden and views beyond and the lightness of its construction. The contemporary design contrasts but sits well with the Edwardian character of the original property.

Detailed technical design, specification & project management

The new structure, external envelope, roof finishes and internal partitions and fixtures were built off-site using modular construction, to minimise the on-site disruption to the family, and was transported to site in four modules and fitted in place within a single day.

Our services included detailed design and specification of the extension and the fit-out of the interior and full project management and contract administration.

Moduloft was the Contractor responsible for the final design and implementation of the pre-fabricated elements.


The development is located in Crouch End, North London.
