Loft Conversions
in Portsmouth and Hampshire

Many properties across our home county of Hampshire, and especially those in the built-up Portsmouth area, have a lack of space to contend with. If you are one of the many local homeowners who need added living space but feel reluctant about moving, C. Lillington Carpentry can help. We have experience in the field of loft conversions and can take on the management of your project from design to completion.

Once your architect and surveyor have confirmed suitability for a conversion, we will perform an inspection of the current space and provide a detailed quotation of works and costings.

Should you accept our quotation, we will arrange the material deliveries and assign a start date for the job. Even trickier loft conversions, including those where we need to join two dormers on a flat roof, are never a problem for our builders, carpenters, joiners and wider team of tradespeople.

We can convert lofts in the following styles:

  • Pitched Roof Dormer
  • Flat Roof Dormer
  • Double-Pitched Dormer
  • Mono-Pitch Dormer
  • Mansard Dormer
  • L-Shaped Dormer
  • Low Ridge Dormer
  • Hip-to-Gable Style


Call C. Lillington Carpentry now to arrange a quotation. We also specialise in rooflight installations and conversions.

Complete Project Management

When starting work on loft conversions in Portsmouth or the Hampshire area, we clear the attic space, reinforce the rafters (if required) and perform a full electrical wiring, plumbing and heating upgrade. In our capacity as carpenters and joiners, we work skilfully alongside all assigned trades to not only build, but to provide 1st- and 2nd-fix services too.

As the conversion progresses, we make improvements to the roof structure and, as the job reaches a conclusion, we also paint, decorate, lay the flooring and apply the finishing touches.

Loft conversions, based on the final style chosen, may require planning approval and could also be subject to the Party Wall Act. On these projects, we liaise with your local authority at regular intervals to ensure compliance with the UK Building Regulations. This reduces the potential for snags at the end of the job and ensures smoother sign-off and certification.
