GS Renovation designs and builds house extensions throughout Angel and N1, adding space to Georgian and Regency townhouses and converted period homes near Upper Street and Highbury Fields. With more than 30 years in Islington, we handle groundworks, steelwork, roofing and fit-out, and guide you through planning and party wall matters from the outset.
Rear and side-return extensions in Angel
The classic Angel extension takes in the narrow side return of a period terrace, widening the ground floor to create a bright kitchen-diner opening onto the garden. We dig and lay foundations to suit the ground and any nearby trees, install steel beams where the rear wall is opened up, and build the new roof and glazing. Every stage is inspected under building regulations so the finished structure is certified.
Whether your project is permitted development or needs a full planning application depends on the property. Many N1 homes sit within Islington conservation areas or are listed, which restricts permitted development rights, so an application to Islington Council is often required. We assess your specific address early, advise honestly on the route, and coordinate party wall notices with neighbours whose boundary the works affect.
Double storey space for N1 townhouses
Tall Georgian and Regency townhouses in Angel lend themselves to considered rear extensions over one or two storeys, adding a larger kitchen below and a bedroom or bathroom above. We match brickwork, detailing and proportions to the age of the house so the addition sits comfortably with the original, which matters greatly in Islington's conservation streets where the council scrutinises how changes read from front and rear.
The build brings together foundations, structural steel, a weathertight roof and a full internal fit-out, all sequenced by one team so trades do not clash. We manage the building control inspections at each key stage, from foundations to insulation and drainage, and handle the party wall process where the extension is built up to or astride a shared boundary with your Angel neighbours.
