Luxury Home Extensions Across the North East

As extension builders in the North East, we work across Newcastle, Gateshead, Durham, Sunderland, Northumberland and the Tyne Valley, delivering contemporary extensions and traditional extensions that look as though they were always part of the house.

Kitchen Extensions Newcastle

Our kitchen extensions in Newcastle and the surrounding suburbs open up dark rear rooms into bright, open-plan family space. Roof lanterns, structural glazing and bifold or sliding doors bring in daylight, while underfloor heating and level thresholds connect the kitchen to the garden all year round.

House Extensions Durham and Beyond

House extensions in Durham, Chester-le-Street and County Durham range from modest single-storey rear extensions to full-width wrap-arounds. Whether you prefer flat-roof modern extensions with hidden gutters or pitched-roof traditional extensions in matched brick and stone, the structure, insulation and detailing are engineered to the same standard.

Orangery Builder and Garden Rooms

As an established orangery builder, we design orangeries with solid perimeter pelmets, glazed lantern roofs and thermally broken frames — warmer and more substantial than a conservatory, and usable as a genuine year-round room.

Conservatory Conversion and Garage Conversions

A conservatory conversion replaces cold polycarbonate or glass roofs with an insulated warm roof and upgraded glazing, transforming an unused space into a comfortable snug or dining room. Garage conversions apply the same thinking to underused space at the front or side of the house, adding a home office, utility or bedroom without extending the footprint.

Planning Permission and Design & Build

Our design and build service covers everything: free 4D virtual design so you can walk through the space before work starts, planning permission handled on your behalf, Building Regulations and structural calculations included, full project management, a fixed-price quotation and a 10-year guarantee. One family-run team, one point of contact, from first sketch to final handover.
