The building status charts the point at which the building has
reached in terms of its life from the beginning as a vision or
pre planning to the end where it is demolished, cancelled or ruined.
Complete – Once a building is finished both externally
and internally and tenants are able to move into it then it is
Under Construction – As work begins on site to build the
building then it is considered under construction. This does not
include the demolition of the existing building as in cases developers
may demolish the building on site and then wait years before commencing.
This does not include actual groundwork either, again preparing
the site may be done years before construction. Construction begins
when the very first part of the building is set down.
Approved – After a project has been officially approved
by the authorities and successfully progressed through the planning
system to the point it can begin then it is considered approved.
The applicant does not have to discharge conditions for us to
grade it this way.
Proposed – Once an application has been officially announced
for a development it is considered proposed.
Pre Planning – Pre Planning refers to projects which are
not officially released and still under work. They may be projects
undergoing feasibility studies for example and are not solid.
Buildings with this classification may change details before being
officially proposed. This is however considered a sub-category
Vision – Architects and developers come up with all sorts
of madcap schemes. These are normally to launch a practise or
show off new technologies and have no realistic chance of ever
being built. Buildings such as Vortex in London go in this category.
Cancelled – Projects which have been dumped for whatever
reason go in this category. Once a project is withdrawn from the
planning process and not resurrected in very similar form it gets
classified as cancelled. Minor revisions do not count as a cancellation
however a completely new design does see the old one cancelled
– for example the Broadway Malyan London Bridge tower is
considered cancelled. Buildings which have had planning permission
refused and are being appealed are considered as still being proposed
until the applicant is unable to progress with the process any
Demolished – Demolished refers to buildings that have been
demolished. This includes partially collapsed ruins that were
knocked down. As even a fire or bombing will leave some remains
and ruins it is up to man to physically remove the building and
anything that has been done so such as Old St Paul’s in
London comes under this category. If part of the building remains
it is classified as ruined.
Ruined – One issue with traditional statuses of other
websites is they do not take into account structures and buildings
that are partially destroyed. Classic examples of this include
the likes of Fountains Abbey, 52m tall and very eligible for inclusion
and yet not inhabitable. We have expanded the range to include
uninhabitable buildings. You might think what’s the point
but it does have a useage as do most ruined protected buildings,
in this case it is a museum.
Completion date – This refers to the date where the building
had finished construction. In the case of buildings such as cathedrals
it is the date the last major addition was built, this does not
normally include restoration work, hence St Albans Cathedral was
not completed in 1913.
Construction start – This is the year that the building
started construction. The time between this and the completition
date is how long it took to build. In some cases it may be hundreds
Proposal date – Proposal date is the date that the building
was officially proposed.
Heights and Floors
One of the vital things of classifying any building is how tall
it is and how many floors the structure has, particularly if you
are doing a heights based site.
Height (Roof) – For this we count the height of the building
from ground level to the roof. Buildings may have been built on
a hill so the height from ground level is different around each
side of the building. We count the face of the building that has
the greatest height from ground level to the roof.
Spire Height – Buildings often have additional structures
above the height of the roof or a more traditional spire. This
is classified as spire height even if it is not strictly a spire
in a traditional sense. The type of structure of this additional
height is classified below. Peaked roofs such as that on 1 Canada
Square do not count as spires. We come to this height by adding
the taking the height of the spire and combining it with roof
height. This is the maximum height of the structure.
Top Floor Height – This refers to the height above ground
level of the top floor. Again it is measured from the highest
building face to ground level.
Metric > Feet – We enter our heights in metres not feet.
As a result our system uses rounding that may produce feet heights
slightly off as there are a little over 3ft in a metre and it
will round to either up or down depending on which is more accurate.
To get an accurate figure on building heights it is best to use
the metric option which is accurate. This is also the case with
the amount of floor-space in the building.
The reason we enter heights in metres is that thanks to metrification
developers tend to announce their building heights in metres and
the press round for feet. Using the rounded version with feet
as the base converting to metres will produce even more inaccurate
results. All sites use rounding systems to display either the
number of metres or feet but we are the only ones honest about
Our system does allow us to enter decimal places and we do so
if they are available allowing us to be accurate to the centimetre,
hence HSBC Tower in Canary Wharf is 199.5m rather than 200m as
listed elsewhere. Feet heights will be accurate if decimal places
have been entered after the metre figures for the buildings.
Floors (OG) – This is the number of floors a building has
above ground. It will include plant floors if these numbers are
Plant Floors – A plant floor typically contains machinery
for the operation of the building, it is not a ‘normal’
floor. The number of these floors are also included in the total
floor count of the building.
Basement Floors – Basement floors are all floors below
ground level. It may in rare cases not be the entrance as some
buildings have entrances raised above ground level.
