Our Recent Work
Cresswell
We recently completed a full house renovation that completely reimagined a family home, including an impressive loft conversion.
This ambitious project involved lowering the ceilings on the existing floors and raising the roofline to unlock the full potential of the property. The result? A stunning, modernized home that offers exceptional living space, functionality and style.
We’re excited to showcase one of our latest projects: a hip-to-gable rear dormer loft conversion that reimagined the loft space of a family home.
The result? A luxurious new master suite complete with a walk-in wardrobe and a spacious, modern bathroom. We designed a generously sized master bedroom, perfectly proportioned to create a relaxing retreat. The large space accommodates a king-size bed and additional furnishings, with natural light pouring in through beautifully placed Juliette Balcony.
We’re thrilled to share the results of our recent project: an L-shaped dormer loft conversion that transformed a mid-terraced family home in South East London into a spacious and functional haven.
Designed to maximize every inch of the loft, this project added two beautiful bedrooms and created a bright, inviting space for our customer and their growing family.
