You have ideas for the house.
But you’re not sure

Perhaps there’s an approved design, but the layout doesn’t feel right for your family.
You want the living spaces to open onto the garden, room for everyone to gather, and somewhere to retreat.
You want to make the most of the site, without losing control of what you spend.
Before you buy, we assess your plot or shortlist against the home you have in mind.
When you’re ready to design, we develop options so you can see how your priorities work together, and where you need to make choices.

Guia Residence
Cascais · Completed 2025
A couple based between Latvia and Switzerland wanted to make Cascais their main home. Their plot came with approved plans; we reworked the design around the way they wanted to live, with higher ceilings, open living
spaces and privacy from close neighbours.
Sheltered terraces extend the living spaces into the garden. A dense garden and an elevated pool in glass bring shade and privacy to the outdoor areas.

Generous openings connect the living spaces with layered terraces and views across the landscape.
Travertine, oak and black steel bring warmth to the interiors.

- Rolf B.Business Owner, USA"Doing this over the distance, it was a little tough for us to commit initially, but Joel's communication was just so simple and easy.
He has a nice customer backend, that really keeps you up to date, with everything going on, which worked great given the distance and time difference." - Claudia L.Business Owner, USA“Living overseas limited our availability, but Joel was able to overcome this difficulty by preparing methodically for our infrequent visits.
His presentations were thorough, efficient, with all consultants as needed, questions anticipated.”

Before you start
What it could cost, how long it could take
and how much of your time it will need.
and how much of your time it will need.
The size of the house is only part of the picture.
The plot, ground conditions, outdoor spaces, materials and level of finish all affect what you’ll spend.
We discuss your overall budget from the start, including construction, professional fees and other project costs.
During concept design, we develop an initial construction budget alongside the design, so you can weigh your options before moving into detailed development.
That initial budget is a planning tool. Detailed pricing follows further design, specifications and contractor proposals.

Our Concept Design Program takes eight weeks.
That gives you the layouts, visualisations, initial construction budget and a direction for the next stages.
The full journey also includes design development, approvals, detailed design, contractor selection and construction.
We map these stages around your project and discuss what could affect the timing, including decisions that depend on the authorities or contractors.
If you have a particular move-in date in mind, bring it to our first conversation.

You work directly with Joel.
We lead the architecture and coordinate the specialists, planning process and architectural support during construction.
You stay involved in the decisions that shape your home, with meetings and any necessary visits planned around the project and your availability.
We explain the options and what needs your approval, so you can make decisions without coordinating every consultant yourself.
The responsibilities of our team, the contractor and any other appointed professionals are agreed before each stage.

SITREP is useful when there is still a plot decision to resolve.
It is not a required first step for every project.
