Measure the space that could become useful
The roof survey records relevant geometry, accessible structure, obstructions and existing services. We distinguish usable circulation and standing areas from lower zones that may serve a different purpose. A plan showing only the perimeter can exaggerate the practical room available under a slope. Furniture and activities help test the measured space before a preferred arrangement is selected.
Available drawings and records of previous work are reviewed with current conditions. An existing rooflight, boarded floor or informal access does not establish the basis on which alterations were made. We identify the information still needed for the present proposal. The design should not carry an uncertain account of concealed construction forward as though it were a verified survey finding.
Confirm the right to use the roof
Ownership information matters before a scheme relies on the space. For an upper apartment, the lease and related documents need appropriate professional review; occupation of the rooms below does not by itself establish control of the roof or structure above. We define the physical changes so that relevant questions can be asked about the actual proposal rather than a general aspiration for extra accommodation.
Shared services, external fabric and access arrangements can create additional interfaces. We identify who needs to receive information and which responses remain outstanding. A design should distinguish those dependencies from the owner's preferences. This prevents a promising layout from appearing further resolved than it is when an essential right or shared-building requirement has not been established.
Consider the stair and existing rooms together
The stair location affects circulation on the current upper floor as well as the proposed roof room. We compare options with existing doors and furniture represented, checking what each arrangement changes below. An apparently spare corner may be important to another room's access or use. The connection is therefore assessed across the home, not added after the new accommodation has been arranged.
Appropriate technical advice addresses access and escape in relation to the complete dwelling. Relevant headroom, floor and structural questions are coordinated with that assessment. We identify where further investigation is needed before dimensions or positions are treated as fixed. The room plan should develop with those requirements rather than depend on an unexplained stair or opening that somebody is expected to resolve later.
Read the roof as part of the building's character
The council's Spitalfields character material describes composed domestic architecture, while its conservation mapping helps locate individual properties in their relevant setting. A roof proposal should be assessed against the actual building and surrounding views. We avoid assigning a presumed historic roof type to a house simply because of its address or treating a neighbouring alteration as an established model for the work.
Proposed rooflights, dormers or other changes are compared for their internal benefit and external effect. Usable height, daylight, privacy and the relationship with retained construction all influence the choice. Materials and junctions should be described clearly enough to explain the intended result. Where a feature needs further assessment, that requirement is recorded before a preferred detail is presented as settled.

Develop a room that can be used and maintained
Discuss the furniture, storage and activities intended for the accommodation. Low areas may provide useful capacity if their access and construction are coordinated, but they should not become a place to conceal unresolved services. Controls and equipment needing attention require practical positions. The design tests these matters with the room furnished, rather than assuming empty-space access will remain available after occupation.
Relevant advisers coordinate structure, environmental performance and weather protection with the layout. Important details are documented before finishes cover them. At handover, keep the relevant records and explain maintenance access clearly. Book a feasibility visit with plans, photographs, earlier alteration records and ownership information, together with an account of how the roof accommodation would support the household.
Before work begins
Loft conversions in Spitalfields: questions
Does an existing loft access mean the space can become a room?
The access is one condition to assess, not proof that the proposed use is suitable. Ownership, structure, geometry, the dwelling arrangement and relevant approvals all need consideration. We identify the evidence and technical advice required before treating an accessible roof void as accommodation ready for conversion.
Can the stair be designed after the loft bedroom layout?
It should be considered with both the new room and the floor below. Its location can affect circulation, usable space and existing rooms. Testing it early allows options to respond coherently, instead of fixing a bedroom arrangement around a connection that has not been shown to work.
How do retained roof features influence the design?
Their position, condition and significance need assessment for the individual building. The design then explains how the proposed accommodation and any external changes relate to them. We do not assume a feature can be removed or copied from another property without understanding its role in the actual construction and character.
What is important for a roof proposal above a flat?
Relevant lease and ownership documents should be reviewed by the appropriate adviser, alongside shared-building and technical questions. The apartment's location below the roof does not establish control of every affected part. The enquiry records the interfaces and responses needed before the design depends on altering them.
What should I prepare before discussing a loft conversion?
Bring available floor and roof plans, photographs of accessible conditions and records of earlier changes. Include relevant title or lease information and explain which existing rooms must remain useful. These help focus the initial assessment on the proposed use, its connection to the home and the evidence still required.
