Your dream space is just a conversion away!

Transform your unused garage into valuable living space

In London, where interior space is limited and every square metre matters, a garage conversion is one of the smartest ways to unlock your home’s potential. Whether you're living in a compact terraced house or a larger suburban property, converting an underused garage into a practical room can significantly improve day-to-day living while adding long-term property value.

Common uses for a garage conversion in London include:

  • Home office – With remote work on the rise, more homeowners are turning garages into quiet, purpose-built workspaces.
  • Guest bedroom or en-suite – Perfect for hosting family or creating a private retreat.
  • Home gym or yoga studio – No commute needed, just convenience and flexibility.
  • Children’s playroom or teenage den – Safe, accessible, and away from main living areas.
  • Self-contained annexe – Ideal for rental income, older relatives, or independent young adults.

With high property prices in areas like Clapham, Hampstead, and Walthamstow, investing in a garage conversion provides a practical way to increase livable space without moving or extending.

What’s possible with a garage conversion in London

At London Core Construction, we understand that no two homes are the same. That’s why we offer a wide range of conversion types to suit every property layout, structure, and requirement.

Types of garage conversions we specialise in:

  • Attached garage conversions
    Easily integrated into your main home layout, ideal for adding living rooms, offices, or dining spaces.
  • Detached garage conversions
    These work well for creating independent studios, workshops, or guest accommodation with separate access.
  • Single garage conversions
    Ideal for smaller homes where every square foot counts. A single garage can comfortably become a compact bedroom, utility room, or office.
  • Double garage conversions
    Offers more design flexibility. Create a large open-plan family room or divide the space into multiple functional areas.
  • Partial conversions
    Perfect for homeowners who still need some storage or parking. One part becomes living space, the other retains its original use.
  • Under-structure and basement-level garages
    In certain London homes, garages sit below living areas. These require careful damp-proofing and insulation, but provide excellent options for quiet office spaces, media rooms, or wine cellars.

We carry out a full structural assessment before proposing conversion ideas, ensuring that your project aligns with building control standards and your home’s design.

Planning permission and building regulations in London

One of the most common questions we hear is: Do I need planning permission for a garage conversion in London?

In most cases, planning permission is not required. This is because garage conversions often fall under permitted development rights, particularly when:

  • The external structure is not significantly altered
  • The converted space is part of the existing home footprint
  • The garage is not being turned into a separate dwelling

However, certain situations do require planning approval, such as:

  • Homes in conservation areas or listed buildings
  • Detached garages being converted into independent homes
  • Structural changes that affect the building’s appearance

Every London borough has slightly different rules, so whether you're in Camden, Kensington & Chelsea, Croydon, or Enfield, our team manages the process from start to finish. We work directly with your local council, prepare and submit plans, and ensure full compliance with all required permissions.

We also guarantee compliance with UK Building Regulations, covering:

  • Part L (energy efficiency)
  • Part B (fire safety)
  • Part M (accessibility)
  • Part P (electrical safety)

All work is signed off by certified building control inspectors, giving you peace of mind and full documentation for future property sales.

Cost of a garage conversion in London

Garage conversion costs in London typically range from £18,000 to £35,000, depending on size, complexity, and the level of finish. While prices can vary, a garage conversion is often much more affordable than building a new extension or moving to a larger home.

Factors that influence garage conversion costs:

  • Garage type – Single vs double, attached vs detached
  • Structural modifications – Load-bearing walls, roof changes
  • Plumbing and electrical installations – Particularly for bathrooms or kitchens
  • Heating and insulation – Required to meet habitable standards
  • Interior finishes – Flooring, lighting, fitted storage, or bespoke carpentry

Return on investment (ROI):
A professionally finished garage conversion in London can increase property value by 10 to 20 percent, especially in high-demand boroughs where square footage drives pricing. This makes it a more cost-effective solution than loft conversions or new builds, with shorter project timelines and less disruption.

Energy efficiency and insulation for converted garages

For a garage to be considered a habitable room, it must meet energy efficiency requirements as set out in Part L of the Building Regulations. At London Core Construction, we integrate sustainable design and smart technologies to ensure your converted space is warm, dry, and cost-effective to heat.

Our standard energy features include:

  • High-performance insulation in walls, floors, and ceilings
  • Double or triple-glazed windows with energy-rated frames
  • Air-tight doors and thermal bridging prevention
  • Underfloor heating with zonal thermostats
  • Ventilation systems that meet airflow standards and prevent condensation
  • Damp-proof membranes and breathable materials for below-ground garages

We also offer eco-conscious materials upon request, helping reduce your carbon footprint while improving indoor comfort. Whether you're converting your garage into a home gym or a guest suite, our goal is to create an energy-efficient, compliant, and enjoyable space for year-round use.

Why a garage conversion adds long-term value in London

A garage conversion adds liveable square footage, which has a direct impact on a property’s market value. It also provides flexible rooms that cater to today’s lifestyle demands—such as home offices, guest rooms, or self-contained spaces for multigenerational living. When designed as a studio or annexe, it can even generate rental income.

Unlike full extensions or moving house, a garage conversion offers a more cost-effective, straightforward upgrade. In many parts of London, particularly Fulham, Dulwich, and Muswell Hill, buyers are more interested in usable interior space than traditional garages. With easy access to public transport and increasing acceptance of on-street parking, converting your garage can give your home a competitive edge and justify a higher asking price in a fast-moving market.

Our 5-Step Project Timeline

Initial Consultation

We begin every garage conversion with a face-to-face consultation at your London property. This first step is all about understanding how you want to use the space and what’s technically possible based on the existing structure. Whether you’re envisioning a home office, guest suite, or functional annexe, we’ll assess the condition of the garage, listen to your requirements, and walk you through the best approach. At this stage, we also outline likely planning or building control needs, ensuring everything is clear from the outset.

2

Planning & Design

Once the vision is agreed, we move into the planning and design phase. This is where practical ideas become detailed plans. Our team works with experienced architects and planning consultants to create a layout that meets your needs and fits seamlessly with the rest of your home. We factor in natural light, insulation, access, storage, and finishes while aligning the design with London’s permitted development rules or preparing planning applications if required. All drawings and documentation are handled in-house to keep the process straightforward.

Pre-Construction Setup

Before any building work starts, we organise everything needed behind the scenes. This includes booking building control inspections, ordering materials, scheduling our trusted trades, and ensuring your home is ready for construction. We put together a detailed timeline and logistics plan so that once the build begins, it runs smoothly with minimal disruption. This preparation stage also gives you a clear sense of what to expect during the works, both in terms of timing and daily site activity.

4

Build & Execution

With preparation complete, we begin the physical transformation of your garage. Our construction team follows the agreed specifications with precision, managing everything from structural work and insulation to plumbing, electrics, and final finishes. We use trusted materials, comply with Part L and other building regulations, and keep the site clean and secure throughout. During this phase, we remain in close communication to ensure that the build progresses on time and reflects the vision you signed off.
