Home Conversion FAQs

Have questions about conversion remodels? Our team provides answers to common questions homeowners have about the remodeling process.

Your home’s suitability for conversion depends on your city’s zoning and permit rules, your property’s structural strength, and access and layout.

When planning your conversion, you’ll want to be mindful of space for things like stairs or entrances, and whether utilities (plumbing, heating, electric) can be extended to the new space.

It depends on the type of conversion and your city’s regulations. Many lofts, garages, and basements can be converted under “permitted development” rights, but larger projects, like splitting a home into multiple units or major structural changes, usually require full planning permission before starting any work.

Smaller space conversions like garages or attics usually take 2-3 months, while more complex work, like finishing a basement with an added bathroom and kitchenette, can take 6-12 months.

Full property conversions, like turning one home into multiple units, may take a year or longer, depending on permits, design, and construction challenges.

There are many factors that can increase the cost of your conversion. They can often be broken into essential updates and optional updates.

Essential (often required):

  • Structural work
  • Excavation for basements or added headroom
  • Waterproofing and damp-proofing
  • Utility upgrades
  • Access modifications like stairs, entrances, and egress windows
  • Insulation and energy efficiency improvements to meet code requirements
  • Permits, surveys, and professional fees

Optional updates include, but are not limited to:

  • Visual updates like skylights, dormers, or light wells
  • Smart home systems or energy-efficient upgrades beyond minimum standards
  • Landscaping or external changes to match the conversion

The best way to learn specifics about project cost is to contact one of our designers about the project you have in mind.

Yes! A well-planned home conversion can increase your property’s value by adding usable living space. The exact value depends on the type of conversion, the quality of the work and local market demand.

Common mistakes in home conversions include:

  • Ignoring planning regulations
  • Underestimating costs
  • Poor design or layout
  • Inadequate insulation or waterproofing
  • Cutting corners on quality
  • Neglecting access and safety

It depends on the scale of your conversion. Small projects like an attic or garage conversion often allow your family to stay home throughout the work, though some areas may be noisy or disruptive.

Larger projects may require temporary relocation for your family’s safety, construction access, and convenience.

Common home conversion challenges include navigating planning and permit requirements, dealing with unexpected issues like structural weaknesses, managing budgets from hidden costs, and working within design limitations such as awkward layouts or low ceilings.

When you plan your conversion with Neil Kelly, your dedicated project manager will help you plan your conversion, find the right tradespeople, and navigate permits and challenges, so you can focus on the fun of enjoying your updated home.

Home conversions can increase property value, create additional living space, and make your home more functional or personalized.
