Newcastle upon Tyne & surrounding areas
House Extensions in Newcastle
Alpine Extensions designs and builds bespoke home extensions throughout Newcastle upon Tyne and the surrounding areas — a complete service from the first design through planning, Building Regulations and construction.
Extend, rather than move
More space in the home you already love.
Across Newcastle, homeowners are choosing to extend rather than face the cost and upheaval of moving. A well-designed extension can give you the kitchen, family room or light-filled living space your house has always been missing — without leaving the street you chose.
We specialise in designing and building beautiful, practical extensions that are tailored around the homeowner and the property itself. Every design starts with how you actually live: where the light falls, how the family moves through the house, and what the space needs to do in ten years' time.
From the first consultation to the final coat of plaster, everything is handled by one team. You can read more about Alpine Extensions or go straight to our single-storey house extensions service.

Questions
Newcastle house extension FAQs
How much does a house extension cost in Newcastle?+
Extension costs vary depending on size, design, specification, foundations, glazing and the services involved. Rather than quoting a headline figure, we prepare a detailed quotation once we have visited your home and worked through the design with you.
Do I need planning permission for a house extension in Newcastle?+
Some extensions fall under Permitted Development rights while others require a planning application. It depends on your property and what you are proposing. We assess this for you and manage the planning process where it is needed.
Do you handle Building Regulations?+
Yes. Building Regulations and the relevant structural and SAP calculations are managed by us as part of our complete extension service.
How long does a house extension take?+
Timescales depend on the size and complexity of the project, including design, approvals and the build itself. You are given a clearer programme once the design and project requirements are established.
What areas around Newcastle do you cover?+
We work throughout Newcastle upon Tyne and the surrounding areas, including Gosforth, Jesmond, Great Park, Ponteland, Darras Hall, Gateshead, Whickham, Ryton, Wylam and other parts of the North East.
How is the job finished?+
We take care of the building work, electrics, plumbing, heating, insulation and plastering. Your new extension is left plastered and ready to decorate, so the main things left to you are painting the walls and laying your chosen flooring.
