Outgrown the house but not keen on moving? The extension choice usually narrows fast once someone has stood in your garden and looked at the boundaries, the drains and the levels.
A rear extension suits houses with garden depth to spare, and it is what most families choose when they want one large living and dining space across the back. A side extension suits narrow plots and terraces with an unused passage, widening the ground floor and fixing awkward circulation. Going up to two storeys makes sense when you need bedrooms as well as living space, and it is better value per square metre than two separate ground floor projects, though it takes longer and disrupts more. A wraparound turns the corner and gives the biggest gain in one go.
What really moves the figure is groundwork, structure and connections, not the finishes people worry about first. Made ground or a mature tree nearby pushes foundations deeper. A manhole inside the footprint has to be diverted or built over properly with approval. Removing most of a rear wall for one open space means a calculated steel beam and proper temporary support.
Many single storey extensions in Widnes fall under permitted development, but building regulations approval always applies, covering structure, insulation, fire safety, ventilation and drainage. We book the inspections and meet the inspector on site.
Most families stay put through a single storey build. We keep your house sealed until the new shell is watertight, then cut the opening in a short defined window.
