Loft Conversion in Hammersmith
We build full loft conversions in Hammersmith from the client’s architect’s project. Our first conversation addresses inspection hold points and build sequence, 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
A Hammersmith loft programme is assembled from construction hold points rather than a single promised duration. The quotation separates the designed floor, roof, staircase, specialist first fix and final room, then identifies information and inspections required before each can be concealed. The architect and engineer appointed by the client provide the project information. We execute it and record where a drawing query or specialist decision could stop a dependent trade.
Measure the house that will carry the new room
We compare accessible roof and floor dimensions with the issued plans, recording support positions, headroom, current openings and the proposed stair route. A discrepancy is logged while the team is still planning, not left for the day the member arrives. We note which existing areas may need controlled opening to establish a concealed condition. Those findings guide the engineer’s response and the inspection plan; a visual survey alone does not certify a habitable floor.
Construction sequence for Hammersmith
| Stage | Our operation | Decision before next stage |
|---|---|---|
| Design review | Compare the supplied project with the inspection hold points and build sequence 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 design review turns drawings into a sequence of hold points. The client and their appointed professionals establish the permission and Building Regulations route for the actual property. We check that the roof, floor and stair information issued for construction fits together and that specialist installers have the details they need. Our written scope records which decisions belong to the design team and which activities we carry out; we do not claim to prepare architectural plans ourselves. The appointed professionals establish the permission and building-control route. We record which drawings control the build, who responds to a change and which stage must remain open for a required check.
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
Site setup follows the order in which checks must occur. Protection is fitted to occupied rooms, materials are staged for the current operation and temporary weather cover is ready for roof work. We tell the relevant professional when the structural connection or insulation layer will be visible. If an inspection cannot happen, the sequence is adjusted so another safe task proceeds while that work remains open. Boarding is not used to hide a delay.
Build the designed floor and roof alteration
Supports, beams, joists and roof framing are installed to the engineer’s information. The team checks bearing, levels and the stair opening before sheathing or closing a junction. Exposed work that requires a review is kept accessible and documented according to the agreed project process. A changed support condition is referred to the designer rather than incorporated as an informal site variation. The roof is protected between stages until the permanent weathering is complete.
Fit the stair into both levels of the house
The stair is an early hold point because its opening passes through the structural floor and may alter the rooms below. We measure both landings and the intended finished levels before the opening is finalised. The engineer’s edge detail, the architect’s stair geometry and any required review are aligned before fabrication. Guarding, handrails and adjoining plaster are completed later, but their fixing and clearances are checked while the supporting construction is still visible.
Sequence qualified first-fix and final connections
Electrical and plumbing specialists enter the programme after the relevant structure is ready and before linings close their routes. They mark penetrations, place first fix and complete the tests or staged checks their work requires. We coordinate this with insulation and plastering rather than booking every trade for the same day. If a service route conflicts with a beam or roof detail, the affected area remains open until the qualified trade and designer agree a revised method.
Close the structure and finish the new room
The release of each concealed stage governs when the team fits insulation, boards and plaster. Once the envelope is closed in the agreed way, flooring, doors, storage and decoration can progress without forcing later inspection through finished work. We check the stair junction and roof-window reveals before final paint. The finish schedule is recorded separately from technical approvals, so a completed appearance does not erase an outstanding certificate or inspection action.
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
Completion is checked in layers. We revisit the external roof junctions and weathering that remain visible, then the stair, floor, services and finished surfaces. We test doors, ironmongery and accessible fittings and record any items to correct. The client receives the agreed trade information and a clear list of any remaining actions. We do not mark the project finished merely because the last coat of paint has dried. We compile the items each trade and appointed party is responsible for, then review visible construction and finishes. Any remaining inspection or completion record is identified by name in the close-out list.
What we establish for a Hammersmith address
At a Hammersmith address, the specific design and council process matter more than a broad neighbourhood assumption. The client’s architect establishes the applicable planning position. We build to issued information and accommodate the relevant staged checks rather than implying that a single generic approval covers every property.
Questions about loft construction in Hammersmith
Which work stages should remain visible for review?
We follow issued engineering details, check positions against the existing house and keep work exposed for required review. Conflicts return to the designer. Exposed supports and connections stay available for review.
How are Hammersmith loft drawings checked against the building?
We measure accessible areas and compare visible conditions with current drawings. Concealed or uncertain construction is referred to the responsible designer or engineer. Measured conditions are compared with the current revision.
What happens if a beam detail changes after opening up?
The client-appointed architect establishes the design and consent route. We build from issued information and refer site discrepancies back before changing affected work. The engineer issues a response before dependent work continues.
When is temporary roof covering arranged?
The actual entrance, landing and rooms determine protection, deliveries and waste handling. We agree the route before structural or roof work begins. Covering and materials are in place before roof opening.
Can the staircase be ordered before the opening is confirmed?
We check the opening and stair against finished levels, doors, headroom and both landings before ordering or fitting. The opening is confirmed against measured stair geometry.
What must the qualified trades finish before boarding?
Qualified trades set routes before enclosure. Installation, tests and records are assigned in writing and coordinated with structure and insulation. Trade tests and assigned checks precede boarding.
How do inspections affect the plastering programme?
Specified insulation and linings follow the required hold points. Plaster, flooring, joinery and decoration are sequenced to protect completed work. Plaster follows release of the concealed-stage hold point.
Which records are named at project close-out?
We inspect the route and room, test fitted items and list adjustments. Specialist records and completion steps remain assigned to the responsible parties. Each outstanding record has a named responsible party.
