The Northowram brief
For an older house in Northowram, Hipperholme or Lightcliffe, an extension should be designed around the existing floor heights, roof form and openings. A new room can be generous while leaving the connection to the original house awkward. Resolve that connection before concentrating on its finishes.
Preparation guidance, not a survey of your property. The location photograph shows the area; it is not evidence of work by ATR.
HX3 / 01
Compare floor heights and circulation
Bring to the conversationAn existing/proposed plan and section through the connection.
Why this matters
Measure both sides of any proposed opening and show the route through the finished house. Consider whether an internal step, altered doorway or relocated service affects the intended use of the new room.
HX3 / 02
Specify the external junction
Bring to the conversationElevation photographs and a junction detail.
Why this matters
Document materials, eaves and window details and check the relevant heritage information. Agree how new work meets the old fabric, including rainwater and maintenance access.
