Loft conversion build in Surrey with rooflights

Loft conversions designed for space, light and comfort

A loft conversion is one of the most efficient ways to add space without extending into the garden. With the right design, you can gain a spacious bedroom, a home office, or a master suite that feels calm and bright.

We deliver dormer, hip-to-gable, mansard and rooflight conversions, tailoring the approach to your roof shape, head height and planning context. If you’re not sure which type suits your property, we’ll guide you through options and trade-offs.

Loft projects require careful coordination of structure and fire safety. We manage Building Regulations, inspections and completion documentation as part of a complete service. If you are exploring your options, you can request a fixed-price quotation or browse recent work in our projects gallery.

How we deliver your loft conversion

We start with a survey and feasibility check, then confirm stair position, room layout, structural strategy and head height. Where required, we coordinate planning permission alongside Building Regulations.

During construction, we aim to keep the home weather-tight and safe, with tidy working practices and clear communication.

We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.
