Domestic Building & Master Joinery Across Crosby & Blundellsands

Homeowners in Crosby and Blundellsands value space, natural light, and architectural quality. Rather than leaving a sought after L23 school catchment or coastal road, extending the ground floor or converting a high pitched loft unlocks huge extra living space.

L23 includes grand Victorian and Edwardian residences in Blundellsands and Waterloo with high ceilings and deep rear plots, alongside classic 1930s bay fronted semis around Chesterfield Road, Moor Lane, and Thornton that are tailor made for hip to gable loft conversions and wrap around kitchen extensions.

Popular Domestic Projects We Build in Crosby & Blundellsands:

  • Wrap around and single storey rear kitchen extensions with roof lanterns or Velux windows
  • Hip to gable and natural slate rear dormer loft conversions with en suite shower rooms
  • Load bearing wall removals and true handleless or shaker kitchen refurbishments
  • Slatted oak ceiling bulkheads, media walls, and bordered herringbone flooring

“RSJ steel installation and kitchen fitting finished to perfection.”

“Stephen and the lads removed our load bearing kitchen wall, fitted the RSJ steel beam, plastered throughout and installed our new kitchen island and ceiling bulkhead. Having a joinery led builder meant every unit, door frame and floor joint was spot on.”
