Working with your builder and designer: getting skylights into the brief early

In many New Zealand projects, skylights arrive late in the story.

Plans are mostly finished. The builder is pricing. Someone notices that the kitchen or hallway still looks a bit dark on paper. A quick note is added: “add skylight?”

Sometimes that works. Often, it leads to compromises – limited positions, more complex detailing, or the feeling that skylights are a last-minute extra rather than part of the home’s daylight strategy.

A different approach is to treat skylights as part of the brief from the very beginning.

This article looks at how to create a skylight design brief in NZ that supports you, your designer, builder and installer. We will cover:

what to include in a skylight brief (goals, rooms, photos, constraints)
who to involve and when (designer, installer, roofer)
how to keep skylights on the table from early concept through to consent and build.

The aim is to help you feel prepared and calm in conversations with your project team, rather than trying to add daylight at the margins.

1. Why a skylight design brief matters in NZ projects

A clear brief does not lock you into exact products or layouts. Instead, it:

captures what you are trying to achieve with daylight
signals to designers and builders that skylights are important to you
helps specialists give grounded advice earlier, when changes are easier.

In New Zealand, where:

roof types vary from metal and tile to membrane
microclimates can shift within a single city
consents and structural considerations matter

… an early, structured skylight brief can prevent later surprises.

2. What to include in a skylight design brief (checklist)

You do not need architectural drawings to start. A good skylight brief can be one or two pages of notes plus some photos.

2.1 Project overview

Include a short description of your project:

is this a renovation, extension, re-roof or new build?
how many storeys will the home have?
what is your region and general climate (e.g. coastal, inland, high wind, frosty winters)?

2.2 Rooms and spaces you want to change

List the spaces where better daylight would make a difference. For each one, note:

room type – kitchen, hallway, stair, bathroom, living, bedroom, office, garage conversion
how you use it now and how you hope to use it after the project
what feels wrong today – gloom, uneven light, reliance on artificial light, dampness.

2.3 Light and comfort goals

Describe what “success” looks like. For example:

“a brighter kitchen island without glare on benchtops”
“a stair that feels safe and welcoming in winter”
“a sleepout that is light for daytime study but dark enough to sleep”
“a bathroom that dries out more quickly after showers”.

This does more than saying “add skylights”. It gives your team something to design towards.

2.4 Photos and simple sketches

Where possible, add:

photos of existing rooms and ceilings
photos of the roof from outside, if safely available
a simple sketch plan showing north, key walls and any obvious obstructions.

These do not need to be technical. They simply help everyone see the same starting point.

2.5 Constraints and non-negotiables

Note any known constraints or priorities, such as:

roof type (metal, tile, membrane) and any planned re-roofing
ceiling type (flat, raked, exposed beams)
budget range for daylight improvements
privacy concerns, neighbour windows, or boundary limitations
specific needs like ageing in place, low-glare workspaces, or reduced condensation.

3. Who to involve, and when

Skylight decisions sit across several disciplines. In a typical NZ project, your key people are:

designer / architect / architectural designer
builder / main contractor
skylight installer (sometimes part of the builder’s team, sometimes separate)
roofer (especially for re-roofs, new builds or membrane roofs).

Early stage – concept and feasibility

At this point, the designer leads. Useful actions include:

sharing your skylight design brief with your designer as part of the initial client brief
asking them to think about daylight from the outset, not as a later add-on
confirming whether there are any obvious structural or planning constraints for skylights.

You can also ask whether they have preferred skylight installers or roofers they work with.

Middle stage – developed design and pre-consent

As floor plans and roof forms settle, it is often a good time to:

invite input from a skylight installer familiar with your roof type
discuss likely skylight positions, types (fixed, vented, tubular, double-height) and shaft options
check how skylight openings interact with structure and services.

Illustrative Example Only: In a Christchurch renovation, a family shared a simple daylight brief with their designer at concept stage. By the time the project reached pre-consent, the designer had already coordinated roof structure for two stair void skylights and pre-discussed flashing details with a roofer, avoiding late changes.

Later stage – consent, pricing and construction

Once plans are heading for consent and pricing, skylights should already be shown in principle on drawings.

At this stage, your builder, roofer and installer will typically:

price skylight supply and installation in context with other work
refine product selection within the agreed design intent
plan sequencing – when shafts, flashings and linings are built.

It is helpful to keep your original brief handy, so that value-engineering does not quietly remove the daylight outcomes you care about most.

4. Keeping skylights on the table from concept to build

Even with a good brief, it is possible for skylights to be trimmed back or forgotten as plans evolve and budgets tighten.

These strategies can help keep them in view.

Make daylight outcomes part of the project goals

In your overall project brief, include one or two daylight goals alongside items like room count and storage.

For example:

“We want to reduce daytime artificial lighting in the kitchen and living area.”
“We want safer, brighter stairs and hallways in winter.”
“We want a healthier bathroom and laundry with better drying conditions.”

This signals that daylight is not optional decoration, but part of how the home should perform.

Ask for daylight diagrams or simple sun sketches

You do not need complex simulations for every project, but you can:

ask your designer to indicate approximate sun paths and key light directions
review how proposed skylight positions relate to those paths
check that priority rooms receive attention.

Seeing even a simple diagram can make it easier to protect skylights if budgets are later reviewed.

Protect one or two “anchor” skylights

If you are concerned about cost, consider identifying:

one or two anchor skylights that are most important to your daily life
secondary skylights that would be nice-to-have.

In discussions about budget, you can then:

prioritise keeping anchor skylights
adjust or stage secondary ones if needed.

5. Checklists by project stage

To make this practical, here are simple checklists you can adapt.

At the very beginning – before design work starts

List the rooms you want to improve with daylight.
Write 1–2 sentences on what “success” looks like in each.
Take photos of existing spaces and, where safe, the roof.
Note your region, roof type and any planned re-roofing.
Decide whether skylights are essential, desirable, or not needed in each room.

During concept and preliminary design

Share your skylight design brief with your designer.
Ask how skylights could be integrated into proposed roof forms.
Check that priority rooms appear to have a daylight strategy.
Flag any special needs (ageing in place, low-glare work areas, moisture-heavy rooms).
Confirm whether a skylight installer or roofer should be consulted now.

Pre-consent and detailed design

Review skylight locations and types on plans.
Discuss shafting, insulation and ventilation for wet areas.
Ask how flashings will work with your roof type.
Check that blinds or control options are considered where needed.
Ensure drawings and specifications reflect the agreed skylight intent.

Pricing and build

Confirm skylight supply and installation are clearly included in pricing.
Revisit your original skylight brief with your builder and installer.
Clarify who is responsible for shafts, linings, flashings and finishing.
Ask how and when you will be able to confirm final product selections.
Keep daylight goals visible in any value-engineering discussions.

6. Planning path – turning your skylight brief into action

Once you have a draft skylight design brief, share it early and refer back to it often.

Step 1 – Draft your brief in simple language

Use the checklists above to create 1–2 pages describing rooms, goals, constraints and non-negotiables.

Step 2 – Attach photos and mark-ups

Add a small bundle of photos and any marked-up plans or sketches. These do not have to be polished.

Step 3 – Share with your designer and ask for feedback

Invite your designer to respond with initial thoughts on skylight feasibility, roof interactions and any obvious structural or consent considerations.

Step 4 – Involve a skylight installer at the right moment

Once roof forms and key room layouts are defined, involve a skylight installer to sense-check positions, types and detailing before finalising drawings.

Step 5 – Revisit the brief at key milestones

Check back against your brief at pre-consent, pricing and pre-build meetings to ensure the daylight outcomes you care about remain in view.

FAQs – skylight design briefs in NZ projects

Q1. Do I need a full set of plans before writing a skylight design brief in NZ?

No. A skylight brief can start with simple notes, photos and sketches. The goal is to describe outcomes and constraints so your designer and installer can guide you, even while plans are still evolving.

Q2. Should I choose exact skylight models before talking to a designer?

It is usually more effective to start with rooms, goals and approximate budget. Specific products can then be selected with your designer and installer, based on roof type, climate and performance needs.

Q3. When is the best time to involve a skylight installer in NZ?

In many projects, it helps to involve an installer once roof forms and key room layouts are defined but before detailed drawings and consents are finalised. This allows practical input without late changes.

Q4. How detailed should my skylight budget be in the brief?

A range or priority list is often enough. For example, you might note which rooms are essential for skylights and whether you are aiming for entry, mid or premium outcomes in each.

Q5. What if my builder suggests removing skylights to save money?

Revisit your brief and identify which skylights are anchors and which are flexible. Discuss options such as staging work, adjusting sizes, or focusing on fewer, better-performing skylights rather than removing them entirely.

Q6. Who owns the skylight design – the designer, builder or installer?

Design responsibility is typically shared. The designer coordinates layout, structure and consents; the installer brings product and detailing expertise; the builder manages sequencing and integration on site. A clear brief helps all three work in the same direction.
