What this work involves
Consider the room from inside and coordinate the opening with structure, roof build-up, operation and shading.
- Position and daylight distribution
- Operation and shading
- Weatherproofing and internal lining
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Compare profile sizes and joints in a sample detail beside the existing facade.
What the drawing needs to explain
Draw a scaled elevation showing existing and new windows together. Resolve the roof-edge, wall and window junction before deciding from an atmosphere image alone.
Allow for later maintenance
Record which elements are new, repaired or retained. This distinction helps identify the appropriate finish and maintenance method for each material later.
Which trade-off matters?
Exact reproduction and a clearly contemporary addition are different design choices. Compare their junctions; an almost matching brick or profile can look less coherent than a carefully chosen contrast.
Cost factors for this service
Costs depend on size, glazing type, structural alterations and finishes. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for roof windows, domes & rooflights. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging roof windows, domes & rooflights?
A larger rooflight does not always give a better result. Consider overheating, privacy and how light is distributed in the room.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
