  • Extensions

    We specialise in house extensions, increasing the footprint of the house, with a minimum of disruption and helping avoid the necessity to move.

  • Loft Conversions

    The addition of a loft conversion greatly adds to the value of a property. If it is not possible to extend the house, this is an effective way to increase the usable space.

  • Refurbishments

    We have completed a number of domestic refurbishment projects in St. Albans and surrounding towns, for a variety of property types.
