Garage Conversions
in Portsmouth and Hampshire

C. Lillington Carpentry can provide your home with the extra space your growing family needs by undertaking garage conversions as a project management specialist. Working with your architectural drawings, we assess the job and use our carpentry and joinery skills, alongside those of all assigned trades, to deliver an exciting and practical new room space.

Located in Portsmouth, we convert garages in all surrounding Hampshire areas. No job is ever too big or too small for us.

A garage conversion is one of the most cost-effective ways to grow your home and enhance its functionality. We assist you with the design and planning, using our experience to not only deliver the job on time and to budget, but to also tackle any potential issues in the specification with professionalism.

Because the structure already has foundations, walls and roofing in place, garage conversions are one of the fastest, most affordable ways to transform your property’s habitable space and turn the build into a home fit for modern living.

All Manual Trades Provided

We are carpenters and joiners supported by builders, plumbers, gas engineers, electricians and a wider range of trades. We work harmoniously as a team, providing 1st-fix and 2nd-fix services around the conversion of garages in the Portsmouth and Hampshire areas. If required to, we also plaster, paint and decorate to give garage conversions a pristine finish.

All internal works, including the flooring and the final fixtures and fittings, fall into our job quotation.

Importantly, all work on garage conversions complies with the UK Building Regulations. Most projects related to garages fall inside permitted development so, based on the original design, you won’t need planning approval from your local authority.


If we do need to deal with building control officers, we do so professionally to reduce the potential for end-of-job snags, and to get the job signed off and certificated sooner.

Building Services – A garage conversion will utilise every skill we have at our disposal. C. Lillington Carpentry has a full team of tradespeople so, when compared to hiring in your contractors separately, projects stay under better control.

Electrical Services – If your planned conversion needs a more substantial electrical supply, we can full or partially rewire garages, and add in extra sockets and lighting, to make your added room space more practical for certain types of usage.

Plumbing and Heating – Homeowners in Portsmouth and Hampshire who wish to use garage conversions as offices, studios, games rooms, man caves or even extra bedrooms will need a hot water and heating source installed by an accredited tradesperson.

We follow a strict process when converting garages:

  • After hearing from you, we schedule a visit to your home and run through the drawings of your architect, or we take measurements and come up with a design of our own.
  • On accepting our quotation, we order the materials and confirm a start date. Our team removes all fixtures and fittings for disposal at licenced waste transfer sites.
  • We start the job, maintaining contact with our customers for the full duration. C. Lillington Carpentry will keep you 100% updated on what is happening inside your garage.
