Why choose a Loft Conversion?

Loft conversions have become increasingly popular among London homeowners, and for good reason. They allow you to maximize your living space without encroaching on valuable garden area, potentially increasing your property's value by up to 20%. With the high costs associated with moving in London, a loft conversion offers a cost-effective alternative to upsizing your home. Whether you need an extra bedroom, a home office, or a relaxation space, a loft conversion can be tailored to meet your specific requirements.

Types of loft conversions we offer

Every home is different, and so are the roof structures and client goals. That’s why we offer a full range of loft conversion types to suit various property styles and budgets. Here's a breakdown of the most popular options we provide:

Dormer Loft Conversion

The most common choice in London, a dormer adds a vertical extension to your sloped roof, creating additional headroom and floor space. Ideal for bedrooms, bathrooms, or offices.

Mansard Loft Conversion

Typically built at the rear of the property, a mansard conversion involves raising the party wall and altering the roof structure to create a nearly vertical slope. These are popular in central London and conservation areas.

Hip to Gable Loft Conversion

Perfect for end-of-terrace or semi-detached homes, this type extends the sloping side roof (hip) out to form a vertical gable wall. It adds significant usable space and can often be combined with a rear dormer for maximum effect.

Velux (Rooflight) Loft Conversion

This is the least invasive and most cost-effective option. Velux rooflight conversions keep the existing roof shape and add skylights to bring in natural light—ideal for newer homes with adequate roof height.

L-Shaped Dormer Conversion

Often used in Victorian or Edwardian terraced homes, this type links two dormers to form an L-shape, offering substantial additional space that’s ideal for large bedrooms, kitchens, or bathrooms.

Each loft conversion is designed with both practicality and aesthetic appeal in mind, ensuring that your new space enhances both form and function.

Is your property suitable for a loft conversion?

Before starting a project, it’s crucial to assess whether your home is suitable for a loft conversion. Fortunately, many London properties—especially terraced, semi-detached, and detached homes—can accommodate a conversion with minimal disruption.

Here’s what we typically evaluate:

1. Head height:
You’ll need a minimum internal height of 2.2 meters from the floor to the ridge beam for a traditional conversion. If your roof is lower, we can explore options like lowering the ceiling below or altering the roof structure.

2. Roof structure:
Older properties with traditional cut timber roofs are generally easier to convert than homes with modern trussed roofs, but both can be accommodated with structural adjustments.

3. Property type and age:
London’s housing stock includes a wide variety of builds. We’ve worked on everything from Georgian townhouses to post-war semis and know how to adapt to each one’s specific requirements.

4. Planning and permitted development:
Most loft conversions fall under permitted development rights, but properties in conservation areas, flats, or those with previous extensions may require full planning permission. We handle all aspects of this process on your behalf.

5. Access and staircase design:
Safe, code-compliant access is essential. We’ll integrate a staircase layout that maximises space without compromising your existing rooms.

We offer a free home assessment to determine the feasibility of your loft conversion and provide honest guidance based on structural integrity, planning constraints, and your personal goals.

Enhance property value with a loft conversion

A professionally built loft conversion is one of the most cost-effective ways to increase your home’s market value in London. On average, a well-executed loft conversion can add between 15% to 25% to your property’s resale value, depending on the location and type of conversion.

Here’s why:

  • Adds usable square footage—critical in London’s compact housing market
  • Attracts more buyers—a 3-bed becomes a 4-bed, or a 1-bath gains an en-suite
  • Improves energy performance—better insulation and modern materials lower heating costs
  • Increases natural light—rooflights and dormers brighten dark homes
  • Flexible use cases—ideal for home offices, guest rooms, or rental income

With rising property prices and limited room to expand at ground level, a loft conversion is not just an upgrade—it’s an investment. We ensure that every pound you spend translates into real, long-term value.

Structural quality and premium materials

At London Core Construction, we never compromise on structural integrity or materials. Every beam, joist, and insulation panel used in your loft conversion meets or exceeds UK building regulations and is sourced from trusted suppliers known for durability and sustainability.

Key features of our build process include:

  • Reinforced Steel Joists (RSJs) for long-term structural stability
  • Thermal and acoustic insulation that exceeds Part L and E building standards
  • Breathable roofing membranes to prevent condensation and enhance air flow
  • Fire-rated plasterboard and doors for maximum safety
  • Double-glazed Velux and sash windows for energy efficiency and natural light

We take pride in using only high-performance materials that stand the test of time. Our team pays close attention to finish quality—from floor levelling to precise joinery—ensuring your new loft feels like a seamless extension of your home, not an afterthought.

Design and planning tailored for London homes

London homes come with unique design challenges, from narrow terraced layouts to listed building restrictions. That’s why our design process is fully bespoke—no templates, no shortcuts. We begin every project by understanding your vision and how your new loft space will fit into your daily life.

Our in-house architectural designers create plans that respect both the original character of your home and the technical requirements of your borough’s planning office. Whether you're in Camden, Islington, or a leafy part of South London, we tailor every design to maximise light, ventilation, and space—all while ensuring structural safety and building regulation compliance.

Our planning team manages all applications, liaises with local authorities, and ensures that every detail—from fire safety to insulation and soundproofing—is meticulously planned and approved.

We also integrate energy-efficient features where possible, including eco insulation, LED lighting, and smart ventilation systems, helping you reduce your carbon footprint while enjoying modern comfort.
