Loft Conversion in Greenwich
We build full loft conversions in Greenwich from the client’s architect’s project. Our first conversation addresses roof form and external detailing, then the structural, roof, stair, specialist and finishing work is set out in a written scope.
- Review the supplied drawings and the actual roof space
- Build the specified structure, roof and staircase
- Coordinate specialists, finish the room and check handover
Site measurements before ordering
Construction to supplied design
Qualified trade interfaces recorded
A visible finish and handover review
Agree the construction package before work begins
The Greenwich quotation starts with the exact roof form proposed by the client’s architect. We identify whether the work is a rooflight, dormer or another alteration shown in the drawings, then define the floor, stair, roof and interior packages that support it. Different external forms create different weathering and structural operations. We record the selected materials and any missing details instead of offering one universal method for all Greenwich roofs.
Measure the house that will carry the new room
We look at the roof as a weather system and a structure. Visible coverings, ridges, gutters, rafters, previous openings and signs of water ingress are recorded where accessible. We measure the loft and stair approach so the interior arrangement can be compared with the proposed external form. A hidden connection is labelled as an investigation point. The architect’s elevations and engineer’s support details are checked against these observations before materials are ordered.
Construction sequence for Greenwich
| Stage | Our operation | Decision before next stage |
|---|---|---|
| Design review | Compare the supplied project with the roof form and external detailing decision | Record missing details and named responsibilities |
| Site setup | Protect the access route and plan component handling | Confirm the actual address and working route |
| Floor and roof | Build the engineered floor and approved roof alteration | Complete relevant exposed-work checks |
| Specialist first fix | Coordinate qualified electrical and plumbing work | Verify routes before enclosure |
| Interior and handover | Fit linings, flooring, joinery and decoration | Review visible work and outstanding records |
Use the supplied plans and assign the decisions
The client’s architect establishes the particular roof form and the relevant planning route. We compare roof elevations and sections with the engineer’s support drawing to see how the new opening will meet the old building. Material selections for covering, flashings and rainwater are recorded before ordering. If an exposed junction differs from the approved detail, the affected weathering is protected while the designer issues a decision; a generic rooflight precedent is not substituted.
Project information and responsibilities
| Requirement | Builder action | Design or specialist input |
|---|---|---|
| Architectural project | Execute the agreed construction | Client appoints architect and supplies plans |
| Structural design | Build specified supports and roof changes | Engineer issues and reviews structural detail |
| Planning and control | Make stages available for required checks | Consent and inspection route assigned in writing |
| Electrical and plumbing | Coordinate programme and access | Qualified trades install, test and record |
| Final finish | Complete agreed flooring, joinery and decoration | Client confirms selected products and finish schedule |
Protect the property and establish the work route
The team plans the external access, temporary cover and delivery of roof components before removing any existing covering. Internal rooms beneath the work are protected, and a clear route for debris is arranged. New membranes, framing and flashings need to be available for the planned opening sequence. If weather or a missing design detail makes the next operation unsafe, we retain protection and reschedule rather than leaving the roof exposed to meet a target date.
Build the designed floor and roof alteration
The engineered floor and roof members are installed to the issued drawings. At a dormer or rooflight opening we check frame position, bearing and line against the retained roof before sheathing. New weathering must meet old coverings, gutters and rainwater details as the approved design requires. We keep relevant interfaces visible for review. A straight plaster reveal inside the room is not evidence that the outside junction will shed water correctly.
Fit the stair into both levels of the house
An attic hatch becoming a permanent route requires coordinated structural and interior work. We form the designed opening, prepare the supporting edges and verify dimensions for the new stair. The stair is then installed with its specified guarding and handrail arrangement, while the landing below is repaired and finished where affected. We do not substitute a visually attractive stair for a design that has not been checked against the actual house. The roof shape can affect the useful arrival zone upstairs. We compare the stair position with finished headroom and the proposed roof opening before final fabrication.
Sequence qualified first-fix and final connections
External vents and electrical penetrations can interrupt weathering if introduced late. The qualified trades therefore mark their routes on the roof and interior drawings before coverings and insulation are finalised. The team coordinates any openings with the architect’s exterior detail, then protects the installed first fix during lining. A new outlet is not placed wherever it is shortest if that conflicts with a designed roof junction. Testing remains with the appropriate trade.
Close the structure and finish the new room
Sloping roof planes, dormer walls and window reveals are lined after the specified insulation and concealed-stage checks. We set out boards so junctions can be finished cleanly, then plaster and prepare the surfaces for decoration. Floor covering and joinery are measured against the built geometry. At the stair arrival, trims bridge old and new levels. We inspect visible finish lines together with window operation and accessible external details before handover.
Where separate trades meet
| Interface | Construction action | Recorded check |
|---|---|---|
| Floor to stair | Form the designed opening and fit the stair | Alignment, finished level and guarding |
| Roof to new room | Weather the opening, then fit insulation and lining | External junction and concealed-stage review |
| Services to walls | Set first fix before boarding | Qualified trade installation and tests |
| Existing to new finishes | Resolve thresholds, trims and plaster edges | Clean transitions and item operation |
Check the completed construction and finishes
Before handover, we compare the result with the agreed drawings and finish schedule. Visible structure interfaces, roof openings, the route from the landing, fitted items and decorated surfaces are reviewed together. The specialists provide the records in their scope, and any building-control completion step remains with the party assigned in writing. We close defects and leave the protected route through the house in the agreed condition. The visible roof junction, window operation and rainwater details are checked alongside the new stair and room finish. Outstanding weathering or alignment items are assigned before close-out.
What we establish for a Greenwich address
Greenwich planning guidance addresses loft and roof extensions, but the decision for a property depends on its address and design. We rely on the client’s appointed designer for that route, and describe only the alteration shown in the issued drawings.
Questions about loft construction in Greenwich
What roof information is needed for a Greenwich loft quotation?
The proposal separates our building work, selected products and the design information supplied by appointed professionals. Drawing changes are priced and sequenced before affected work continues. The proposed roof form, covering and junction detail are reviewed.
When do you decide how the opened roof will be weather-protected?
The actual entrance, landing and rooms determine protection, deliveries and waste handling. We agree the route before structural or roof work begins. Temporary weather protection is planned before stripping.
How is a dormer junction checked against the existing covering?
We follow issued engineering details, check positions against the existing house and keep work exposed for required review. Conflicts return to the designer. We check frame line and weathering against retained fabric.
Does the area name decide whether roof alterations need permission?
The client-appointed architect establishes the design and consent route. We build from issued information and refer site discrepancies back before changing affected work. Permission is established for the specific design and address.
What must be agreed before the staircase is ordered?
We check the opening and stair against finished levels, doors, headroom and both landings before ordering or fitting. Roof geometry and finished floor levels affect arrival.
How are roof penetrations for services coordinated?
Qualified trades set routes before enclosure. Installation, tests and records are assigned in writing and coordinated with structure and insulation. External openings follow the architect’s approved detail.
What is checked at a newly lined rooflight reveal?
Specified insulation and linings follow the required hold points. Plaster, flooring, joinery and decoration are sequenced to protect completed work. The visible reveal is checked after lining and plaster.
Which external details remain part of the handover review?
We inspect the route and room, test fitted items and list adjustments. Specialist records and completion steps remain assigned to the responsible parties. Window operation and accessible rainwater details are reviewed.
