Optimise your space with a home upgrade to improve your living conditions and add value to your property. When going through a home improvement, it’s the perfect time to rethink the way your home uses energy and to make your home more environmentally-friendly. To upgrade your home like this is often referred to as a ‘deep retrofit’ and can have many benefits for both the property and its occupants.  The ultimate aim of a deep retrofit is to achieve a BER A-rating for the upgraded property. In pursuit of that objective, you can expect nühaus to:

  • Make improvements to wall insulation
  • Make improvements to attic and roof insulation
  • Replace windows and doors
  • Review airtightness 
  • Upgrade the ventilation system 
  • Make improvements to electrical wiring 
  • Upgrade mechanical pipework 
  • Install renewable energy technology

These changes aren’t just nice by themselves. Your home will be warmer, cozier and have lower energy bills. If your new space uses renewable technology, we’ll also leverage our SEAI membership to ensure that you get full access to a wide range of grants available for being a ‘green build’.

If your home is one room short of perfection, an attic conversion may be just the thing for you. Reclaim an underused part of your house as a luxurious new space for your family and improve your BER rating at the same time by improving your roof insulation with an attic conversion.

Our attic conversion planning experts can advise on every aspect of your project and, whether there are structural issues, planning applications, site surveys or standard architectural design and project management issues, we’ll take care of everything involved.

A garage conversion is one of the smartest property investments you can make. Many suburban garages are oversized and homeowners are delighted to see the space that was previously used for old paint cans and unused suitcases being put to good use as a functional room. Simple projects of this type don’t usually require formal planning permission and access for building works is easy, but if anything does pop up, rest assured, we’ll handle it for you.

Typically, a garage conversion will involve the installation of a ground floor bathroom, utility room, study room or office but we’ve also helped homeowners with some more exciting dream projects. Our favourites include:

  • A new kitchen with a walkthrough connection to the existing house
  • A fully-equipped gym
  • A home movie theatre/music hall
  • A minibar/lounging room
