Unbeatable Portsmouth Loft Conversions

Grubb & Banks are well-established contractors that have been providing quality loft conversions in Portsmouth since 1987. Our team are highly motivated and strive to exceed expectations on every level. Every Portsmouth loft conversion is installed by our qualified and exceptionally trained tradespeople, and at very competitive prices.

Loft conversions can often be overlooked as the solution isn’t the immediately obvious choice for increasing living space. The loft is usually tucked away, and only ever used to drag out the bundle of Christmas lights and collapsible Christmas tree that you put out once a year. Maybe it’s used for luggage case storage as well, but its potential is going to waste. This is where Grubb & Banks excel, and we can help you design, install and transform your loft into a beautiful living space with our Portsmouth loft conversions.

What Does It Involve?

Our in-house project manager will ascertain your requirements and features you’d like to include in your design and take you through the design process. Once the design is finalised, our craftspeople will set the conversion in motion. Our project manager will oversee the process from start to finish, making sure everything is in line with current building regulations, health and safety standards, fire safety legislation and all planning permission (if required) and design certification is acquired.

In most cases, loft conversions Portsmouth don’t require planning permission. They are instead certified under ‘permitted development’ of the property. This can save time on paperwork and thus expedite project schedules, saving you time and money.

Loft conversions are useful for many reasons, and here are a few ideas:

  • Adding Value to Your Property
  • Increasing Living Space
  • Adding Rooms for Renting
  • Private Studies or Workrooms
  • Secret Hideouts for the Kids
  • Nursery for a New Family Member


We all know how chaotic the housing market can be, what with constant currency fluctuations, economic inconsistencies and all manner of other factors. It can be a frightening prospect trying to sell your property for what you know its worth.

Loft conversions in Portsmouth can help you not only retain maximum property value but dramatically increase the market value as well. It’s an efficient way of converting a three bedroom property into a four or even five bedroom. They present a significant long-term investment for the property and can serve to attract a wider range of potential buyers.

Your extension will be designed to complement your existing structure, and blend seamlessly with the original building. Extensions are fantastic ways to add value and living space to a property, but generally require planning permission and, of course, the spare land required for construction.
