Architectural Design and Planning
A loft conversion is an efficient way to maximize your property's existing footprint by transforming unused attic space into functional living areas. At Extension Planning, we develop detailed loft conversion plans tailored to your roof structure, spatial constraints, and local authority guidelines.
Types of Loft Conversions and What They Achieve
The suitability of a loft conversion depends on your property type and existing roof pitch. We can design several variations to suit different homes:
-
Velux / Rooflight Conversions: The most straightforward option, maintaining the existing roofline. This style utilizes flush rooflights to bring in natural light, making it ideal for home offices or additional bedrooms where existing headroom is already sufficient.
-
Dormer Conversions: A structural extension that projects out from a sloping roof. Dormers create substantial additional floor space and headroom, allowing for standard-height ceilings, versatile room layouts, and the inclusion of an en-suite bathroom.
-
Hip-to-Gable Conversions: Common on semi-detached or end-of-terrace properties with hipped roofs. This design extends the sloping side roof into a vertical gable wall, significantly increasing the internal loft volume and opening up space for a full staircase.
-
Mansard Conversions: A more extensive alteration involving changing the entire slope of the roof. Mansards run the full width of the property and offer the maximum possible volume of new space, effectively creating a new storeys.
The Impact on Your Living Space
Converting your loft allows you to add vital living space such as a master bedroom suite, extra children's bedrooms, or a quiet workspace, without sacrificing your garden or driveway. We focus on critical technical details like staircase positioning, structural support, and fire safety to ensure the new floor integrates safely with the rest of your home.
