A situation to test your plan against
Imagine extending the kitchen while keeping the dining table inside the original house. The addition should also bring useful light to that table. Include the existing room and the place where you read or work in the daytime.
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
Compare glazing, shading and roof openings as one part of indoor comfort.
What the drawing needs to explain
Draw one section through the kitchen, glazing and terrace. Include finished floor levels, the roof edge and shading position; separate supplier sketches do not fully show these relationships.
Allow for later maintenance
Keep glazing and rooflight maintenance instructions together. Leave outdoor surfaces accessible without having to remove permanent furniture or planting.
Which trade-off matters?
A wide garden opening takes away wall space for cupboards. Compare a fully glazed rear wall with a smaller opening and a targeted rooflight, looking at both from the same seat.
Compare the complete intervention
Compare the glazing, rooflight and terrace reinstatement together in the budget. If a cheaper door system requires a different floor build-up, include that consequence in the same comparison.
How to review the result
At completion, walk from the cooking area to the terrace. Check the opening with the intended furniture in place and review the light with any shading closed.
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.
How can the original room avoid becoming darker?
Assess the old and new rooms on one drawing. An additional rooflight becomes a reasoned choice when you know where light is needed and how sunlight and heat will be managed.
