We handle every aspect of your property conversion, from initial design and planning through to the final finishing touches.

Why Choose Biggin Renovations for Your Property Conversion?

Property conversions are complex construction projects that require expertise across multiple disciplines—structural engineering, building regulations, planning permissions, and skilled craftsmanship across all trades. At Biggin Renovations, we bring years of construction experience and comprehensive knowledge to every conversion project, ensuring your transformation is completed to the highest standards, on time, and within budget.

Complete Property Conversion Solutions

We specialise in all types of property conversions, helping Purley homeowners maximise their existing space rather than facing the expense and upheaval of moving house. Our conversion services include:

Loft Conversions: Transform your unused loft space into beautiful bedrooms, home offices, playrooms, or luxurious master suites with en-suite bathrooms. Loft conversions are one of the most cost-effective ways to add substantial living space and property value.

Garage Conversions: Turn your underused garage into valuable living space—perhaps a home office, gym, guest bedroom, or additional reception room. Garage conversions typically don’t require planning permission and can be completed relatively quickly.

Basement Conversions: Unlock the potential beneath your feet by converting your basement or cellar into usable living space. From cinema rooms to additional bedrooms, basement conversions dramatically increase your property’s footprint.

Outbuilding Conversions: Transform sheds, outbuildings, or detached garages into home offices, studios, or guest accommodation, creating separate spaces perfect for working from home or hosting visitors.

Commercial to Residential Conversions: We handle complex conversions of commercial properties into residential homes, navigating the planning and building regulations required for change of use projects.

Whatever conversion you’re considering, Biggin Renovations has the expertise to deliver outstanding results.

Our Construction Expertise

Property conversions demand more than basic building skills—they require structural knowledge, problem-solving abilities, and experience working within existing buildings. Our construction team has successfully completed conversions of every type and complexity across Purley, giving us the expertise to anticipate challenges, suggest improvements, and deliver solutions that work beautifully in practice.

Our comprehensive construction capabilities include:

  • Structural calculations and engineering for load-bearing alterations
  • Steel beam installation for opening up spaces
  • Staircase design and installation
  • Roof alterations and dormer construction
  • Foundation work for extensions and underpinning
  • Damp-proofing and waterproofing
  • Complete electrical and plumbing installations
  • Insulation to current building regulations
  • Plastering, carpentry, and decoration
  • Window and door installation

Every aspect of your conversion is completed by skilled tradespeople who take genuine pride in delivering exceptional quality.

Planning and Building Regulations

Navigating planning permissions and building regulations can feel overwhelming, but Biggin Renovations makes it straightforward. We handle all applications, liaise with local authorities, and ensure your conversion complies with all necessary regulations. Our experience means we know what’s required, how to present applications effectively, and how to address any concerns that arise.

Many conversions fall under permitted development rights and don’t require planning permission, but all conversions must comply with building regulations covering structural integrity, fire safety, insulation, and ventilation. We manage this entire process, ensuring your conversion is fully compliant and properly certified upon completion.

Maximising Space and Natural Light

The best property conversions don’t just add square footage—they create beautiful, functional spaces filled with natural light. We achieve this through careful design, strategic window placement, and features like roof lights, dormer windows, and glazed doors that flood converted spaces with daylight.

Our design expertise ensures your conversion feels like a natural extension of your home, with thoughtful layouts that maximise usability and aesthetic appeal. Whether you’re creating a cosy bedroom or an expansive open-plan living area, Biggin Renovations delivers spaces you’ll love spending time in.

Adding Significant Property Value

Property conversions offer excellent returns on investment. Loft conversions, for example, can add up to 20% to your property’s value—often more than the conversion costs. Garage conversions and other space transformations similarly increase both the usable space and market value of your home.

Beyond financial returns, conversions improve your quality of life by providing the space your family needs without the stress, expense, and disruption of moving house. You keep the location you love, the schools your children attend, and the community connections you’ve built, whilst gaining the extra space you require.
