What this work involves
Room layout, daylight, pipework and finishes are interconnected. Create a room schedule describing use, materials and connection points, and keep changes during construction controlled.
- Survey and investigations
- Demolition and retained elements
- New layout and structural changes
- Building services
- Complete finishing and handover
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Separate functional improvements from interventions changing the recognisable elevation.
Decide this before construction
Assess the existing detail before selecting products. Then coordinate insulation, ventilation and visible finishes so one improvement does not create an unexamined consequence elsewhere.
Which trade-off matters?
New performance and existing proportions need assessment together. A different frame profile can affect glass area, reveals and internal finishes; compare the complete detail, not just the product rating.
Compare the complete intervention
Include internal making good and possible sill adjustments with facade work. Compare options using the complete work package around the opening.
Cost factors for this service
A useful budget is divided by work package and room. Identify provisional sums for undecided products and explain how unforeseen conditions are handled.
Bring this to the discussion
Existing plans, room-by-room requirements, material preferences and temporary living arrangements.
Questions about the work
How is this different from a smaller renovation?
Much of the home is addressed at once. This usually requires closer coordination, more preparation and clearer arrangements for temporary accommodation.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
