Piggyback Loft Conversions: A Complete Guide

Is your family growing, or do you simply crave more versatile living space in your home? If you don’t fancy dealing with all the hassle and expense of moving, a loft conversion is an exceptional way to unlock the untapped potential within your current property. Among the various conversion types available, the piggyback loft conversion stands out as an innovative solution for significantly increasing both headroom and usable floor area.

At Abbey Partnership, we specialise in crafting bespoke loft conversions tailored to your unique needs and property types. In this article, we’ll delve into all the specifics of piggyback loft conversions, exploring what they entail, their distinct advantages, the potential costs involved, and the important regulatory considerations you’ll need to be aware of.

What is a Piggyback Loft Conversion?

A piggyback loft conversion is a more substantial type of loft extension compared to simpler Velux or dormer conversions. The defining characteristic of a piggyback conversion is the removal of your home’s existing roof structure, which is then rebuilt at a higher level. This process involves raising the property’s perimeter walls (the gable and party walls) to create significantly more vertical space. The new, higher roof is then “piggybacked” onto these raised walls.

Essentially, a piggyback loft conversion creates a new storey within your home, offering a generous amount of headroom and a more flexible layout, often feeling like a natural extension of your existing living space rather than just an attic room. This method is particularly effective for properties with shallow pitched roofs or limited existing head height in the loft, where other conversion types might not provide sufficient usable space. The result is a bright, airy, and spacious new level that can be transformed into bedrooms, bathrooms, a home office, or a playroom – the possibilities are extensive.

Advantages of a Piggyback Loft Conversion

Opting for a piggyback loft conversion offers a wealth of benefits for homeowners looking to maximise their living space:

Significant Increase in Headroom

By raising the roofline, piggyback conversions create full-height rooms, eliminating the sloped ceilings that can restrict movement and furniture placement in other loft conversion types.

Maximised Usable Floor Space

With increased headroom comes a greater expanse of usable floor area. This allows for more ambitious layouts, including multiple rooms, en-suite bathrooms, and ample storage solutions.

Versatile Design Options

The additional height and space provide greater flexibility in how the new area can be configured. Whether you dream of a luxurious master suite, two generously sized children’s bedrooms and a shared bathroom, or a spacious open-plan office, a piggyback conversion can accommodate any of these visions.

Increased Property Value

A well-executed piggyback loft conversion can significantly enhance the market value of your property. The substantial addition of high-quality living space is always a highly desirable feature for potential buyers.

Improved Natural Light

With the opportunity to incorporate larger windows, skylights, and maybe even Juliet balconies, piggyback conversions can be flooded with natural light, creating bright and welcoming interiors.

Ideal for Low-Pitched Roofs

Homes with shallow roof pitches, which might not be suitable for other conversion types due to insufficient existing head height, can greatly benefit from a piggyback approach.

Seamless Integration

When designed and constructed by experienced professionals like Abbey Partnership, a piggyback loft conversion can effortlessly blend with the existing architecture of your home, appearing as though it has always been part of the original structure.

Costs of a Piggyback Loft Conversion

The cost of a piggyback loft conversion is generally higher than other, simpler loft conversion types due to the more extensive structural work involved in removing and rebuilding the roof. However, the significant amount of high-quality space created often justifies the investment.

Several factors will influence the final cost of your piggyback loft conversion:

• Size of the Property: Larger properties will naturally require more materials and labour, increasing the overall cost.
• Complexity of the Design: Intricate designs, multiple rooms, or specific architectural features will impact the price.
• Roof Structure: The existing roof structure and the complexity of raising the party and gable walls will be a factor.
• Internal Finishes and Fittings: The quality of fixtures and fittings, such as bathrooms, flooring, lighting, and built-in storage, will affect the final cost. High-end finishes will naturally be more expensive.
• Window and Door Choices: The type, size, and number of windows and doors will contribute to the overall expense.
• Structural Engineer and Architect Fees: These professional fees are essential for ensuring the structural integrity and compliant design of your conversion.
• Planning Permission Costs: As piggyback loft conversions typically require planning permission, associated application fees will apply.
• Location: Building costs can vary slightly depending on your location within the UK.

While it’s difficult to provide a precise figure without a site survey and detailed discussion of your requirements, piggyback loft conversions in the UK generally start from around £70k – £90k and can increase significantly based on the factors listed above.

Piggyback Loft Conversion Permitted Development and Planning Permission

Navigating the regulatory landscape is a crucial aspect of any home renovation project, and piggyback loft conversions have specific requirements.

Permitted Development Rights

In many instances, smaller loft conversions, such as Velux or some dormer conversions, can be carried out under Permitted Development (PD) rights. These rights allow homeowners to make certain alterations and extensions to their properties without needing to apply for full planning permission, provided specific criteria and limitations are met. These typically relate to the volume of the extension, its height, its proximity to boundaries, and the materials used.

However, piggyback loft conversions almost always fall outside the scope of PD rights. This is primarily because:

• Raising the Roof Ridge Height: Permitted Development typically does not allow for any alteration that raises the highest part of the existing roof. Piggyback conversions inherently involve raising the roof ridge.
• Significant Alteration to the Roof Shape and Volume: The substantial changes involved in a piggyback conversion usually exceed the volume allowances and design limitations set out under Permitted Development.

When Planning Permission is Required

Because of the significant structural alterations involved, particularly the increase in roof height, you will almost certainly need to apply for full planning permission from your local authority for a piggyback loft conversion.

The planning permission process involves submitting detailed plans of your proposed conversion to the local council. They will assess the application based on various factors, including:

• Impact on the Street Scene: How the altered roofline will affect the appearance of your property and the surrounding area.
• Neighbour Amenity: Ensuring the conversion doesn’t unduly overshadow neighbouring properties or result in a loss of privacy.
• Design and Materials: The aesthetic quality of the proposed extension and whether the materials are in keeping with the existing property and local vernacular.
• Local Planning Policies: Compliance with the specific planning policies and guidelines set out by your local council.

It’s also important to note that Building Regulations approval is a separate requirement from planning permission and will always be necessary for any type of loft conversion. Building Regulations ensure that the construction work meets essential safety, structural, and energy efficiency standards.
