What room Additions covers
A room addition adds enclosed space to a property, either by extending or by converting space that is not currently habitable. Zoning, lot coverage and permit requirements shape what is achievable, and they need checking before a design is settled rather than after.

Adding a room within or onto a property, with the approvals resolved before the design is fixed.
Waystar carries out this work on residential and commercial property in Brooklyn and across New York City. Every project starts with a look at the building, and the scope, the materials and the figures are written down before anything begins.
When might you need it?
These are the signs owners usually notice first.
- A household that has outgrown the property
- A need for a bedroom, office or bathroom that does not exist
- Unused space that could become habitable
- Uncertainty about what zoning actually permits
- Moving being more expensive than adding
What the work involves
- Feasibility review against zoning and lot coverage
- Design developed within what is achievable
- Permit and filing requirements identified and progressed
- Foundation and structure formed
- Envelope closed, insulated and made weathertight
- Services extended and the interior fitted out
How the process works
Check what is permitted
Zoning and coverage decide the envelope before any design work is worth doing.
Design and file
The design is developed inside those constraints and taken through the approvals.
Build the shell
Foundation, structure and envelope, closed and made weathertight.
Fit out and connect
Services extended, interior finished, and the addition tied into the existing property.
What you get
- Feasibility established before design money is committed
- One team from foundation through to finished room
- An addition tied into the existing property rather than bolted on
What affects the scope
- Zoning, lot coverage and setback constraints
- Foundation requirements and ground conditions
- How far services have to be extended
- Approval timescales, which are outside anyone contractor control
This is a preliminary planning range, not a quote. A property visit is required before any price is confirmed.
Frequently asked questions
How do I know if I am allowed to build?
It needs checking against zoning and lot coverage for your specific lot. That check comes before design, not after.
How long do approvals take?
It varies and it is not within our control. What we can do is submit complete information first time.
Will it look like an addition?
It does not have to. Matching materials, roofline and window proportions is what makes an addition read as part of the house.
