Transform an underutilised attic into a refined living space with improved head height, natural light, and premium finishes.
A loft conversion allows you to remain in a prime location while gaining additional space, without estate agent fees, stamp duty, or relocation costs.
Modern insulation, glazing, and construction techniques enhance thermal performance and reduce ongoing energy consumption.
From luxury bedrooms with en-suite bathrooms to private offices or dressing rooms, our bespoke loft conversion designs are tailored to your requirements.
We provide a comprehensive range of loft conversion services in Mayfair, carefully designed to suit high-value properties, planning constraints, and conservation considerations.

A dormer loft conversion is a popular option for increasing head height and usable floor space. This type of loft extension projects vertically from the existing roof, creating bright, well-proportioned rooms while maintaining the character of the property. Dormer conversions are often a practical solution where additional space is required without extensive roof alterations.

A Velux loft conversion involves installing roof windows without altering the existing roof structure. This option is suitable where sufficient loft height already exists and offers a discreet, cost-effective way to introduce natural light and ventilation while maintaining the external appearance of the building.

A mansard loft conversion is ideal for maximising internal space and is particularly well suited to period properties in Mayfair. This type of loft extension alters the roof structure to create a near-vertical wall, providing excellent headroom and generous floor area. Mansard conversions typically require planning permission and are often used on high-end residential properties.

A hip-to-gable loft conversion extends the sloping side of a roof into a full vertical wall. This option is suitable for end-of-terrace and semi-detached properties and significantly increases usable space, allowing for larger or multiple rooms.

An L-shaped loft conversion is commonly used on properties with rear extensions. This design creates a large, versatile loft space suitable for luxury bedrooms, en-suite bathrooms, or additional living accommodation, while maintaining structural balance.
We follow a structured, professional process to ensure every loft conversion is delivered to the highest standard. If you are wondering how long a loft conversion takes, most projects are completed within 4 to 12 weeks, depending on complexity and planning requirements.
Our loft conversion experts assess your loft space, roof structure, and planning requirements while discussing your ideas, budget, and timeline.
We create detailed architectural drawings and tailored designs that comply with permitted development rights or planning permission requirements.
We manage planning applications where required and ensure full compliance with UK building regulations, including fire safety, insulation, and structural standards.
