Working with your Architectural project team on a new home, house extension, or development project is always an exciting adventure, however, the hundreds of technical architectural terms we use can be confusing.
Whilst Architectural words and phrases form part of our daily discussions, for someone new to our world it can indeed sound like a foreign language.
To help you better understand this dialect of industry acronyms and colloquialisms we have put together a list of the most common phrases you might hear being used by our Architect team when planning your next building project.

Aesthetic – The appearance of something.
Arcade – A covered walkway lined by columns.
Archway – An opening with a curved or pointed top.
Asbestos Survey – A survey undertaken on a property to identify if asbestos-containing materials are present.
Architectural Symmetry – Characteristic by which the two sides of a facade or architectural floor plan of a building present mirror images of one another.
Balcony – A platform that projects from the wall of a building.

Building Envelope – The elements that wrap a building – the outside of the total building.
Build Over Agreement – Compliance for when your extension or conversion takes place near or over a public sewer to confirm the foundations of your new construction have given sufficient clearance from the sewer and that access will still be possible if the need arises. An application to the water authority will need to be made and a fee paid.
Cantilever – A long projecting element fixed at only one end, with no columns to support it.
Casement Window – A window frame that is hinged on one vertical side or at the top, and which swings open to either the inside or the outside of the building.

Contamination Report – A Phase 1 report by a specialist is often needed to accompany a planning application when a barn conversion or new home is proposed to check if any previous use on that land would cause a risk to future residents of a dwelling or other new use. If contamination is predicted then a Phase 2 report will be required, complete with soil and other tests if asked for in the planning conditions, followed by a Remediation Report and finally at the end of the build by a Verification Report.

Parapet – Usually a piece of wall that protrudes up above a flat roof, for example, to hide a gutter when you build close to a boundary
Party Wall – A wall, also known as a common wall that is a dividing partition between two adjoining buildings that is shared by the occupants of each residence or business. If you need to cut steel beams into a party wall then a party wall agreement is required.
