We design dual occupancy homes across Tasmania that get more from your block, whether for family, rental income or both, and guide you through approvals to build ready plans.
Dual living sounds ideal until you try to make it work. How do you give two households privacy, keep the design within budget and still satisfy council. Get the layout wrong and you end up with two homes that feel cramped, exposed or compromised.
We design dual occupancy homes that give each household its own space, light and privacy while making the most of the block. Every layout is shaped around how the homes will actually be used, whether that is extended family or an income stream. Nothing gets drawn that pricing will later take away from you.
We had no idea where to start with our new home and Strait Design made the whole thing feel simple. They designed to our budget from day one and kept us informed the whole way through. Could not fault them.
After a bad experience elsewhere we were nervous, but this team told us the truth about timelines and cost upfront. No surprises and no excuses. Our plans were build ready exactly when they said they would be.
The approvals process terrified us but Strait Design handled all the council side so we did not have to. Everything was explained in plain English and we always knew what was happening next. Brilliant service.
We wanted a double storey family home and were worried about blowing the budget. They shaped the design around what we could actually spend and it still turned out beautiful. Would recommend to anyone building.
As a small developer I needed speed through approvals and accurate early costing. Strait Design delivered both. The documentation was clear enough for builders to price it properly the first time around.
What stood out was the communication. We never had to chase for updates because they always let us know where things sat. Dealing with one team from start to finish made the whole process so much easier.
Over 35 years of experience really shows. They picked up issues early that we never would have and saved us money down the track. It genuinely felt like they had our best interests at heart the entire time.
We are first home builders and had a hundred questions. The team was patient, down to earth and never once made us feel silly for asking. Our build ready plans came through exactly as promised. Thank you.
From the first call to the finished plans the experience was exactly what they said it would be. Trade qualified people who actually know planning and building inside out. Honestly worth every single cent.
A dual key home gives you two self contained living areas within a single dwelling, ideal for a teenager, an ageing parent or a tenant. We design the split so each side works on its own while keeping the build efficient. We help you engage the right builder with documentation clear enough for accurate, comparable pricing.
Your design is reviewed by people who build homes for a living. Get practical input on structure, materials, thermal performance and cost before decisions are locked in.
Stage one finishes with a Project Budget Alignment Estimate based on real project data and current construction rates, so you can check the design against your budget before it goes to council.
Your design fees, consultant allowances and council costs are set out upfront. We explain provisional costs and discuss any additional requirements with you before proceeding.
We guide your selections and document them in your construction drawings, giving builders a clear basis to price the fixtures, fittings and finishes you want.
We coordinate surveyors, engineers, energy assessors, your building surveyor, council and TasWater where required, keeping your pre-construction work moving through one team.
Regular, clear updates explain where your project is at, what comes next and anything we need from you, so you can make decisions with confidence.
A side by side duplex brings its own planning and titling questions, and we manage the process for you. We prepare the documentation and handle the planning and building approvals so you are not left decoding council requirements on your own. You are kept informed at every stage, so you always know where things sit and what happens next.
We talk through your budget and your goals before any design work begins, so you know what your dual occupancy will cost and what it can return. Construction estimates are prepared alongside your approvals. Our timeline and cost guarantees (terms and conditions apply) mean you can plan and finance the project with certainty.
Timing depends on the size of the project, your block and what council requires. We give you a clear timeline at the start, before any work begins, so you can plan and finance around it. Our process is built to keep your dual occupancy moving through design, documentation and approvals without long stalls. We back that timeline with a guarantee, and terms and conditions apply.
That depends on the size of the block, its access, orientation and the planning rules that apply. It is one of the first things we help you work out, so you are not committing on a hunch. If the block has constraints, we will tell you early and honestly rather than after you have spent money. That way you know whether dual occupancy designs stack up on your property before you go further.
Dual occupancy usually means two separate dwellings on one block, while a dual key home places two self contained living areas within a single dwelling. Which one suits you depends on your goals, your block and how you want to use or rent the space. We help you weigh the options honestly before any design work begins. That way the path you choose fits your budget and what you are trying to achieve.
Bring your budget, details about your block and a clear sense of how the two homes will be used. Examples of dual living home designs or side by side duplex designs you like are helpful too. You do not need everything worked out before you get in touch. Working through the details with you is part of what we do.
Changes are a normal part of shaping a dual occupancy design, and we refine it with you until it works for both households. The best time to make changes is during the design stage, before documentation and approvals begin. If you want to change something later, we will tell you how it affects your timeline and cost before anything happens. You stay in control of every decision and every dollar.
Yes, we help you engage the right builder once your plans are build ready. Your documentation is prepared so builders can give you accurate, comparable pricing on your dual occupancy or dual key home. We can help you work through the quotes so you understand how they compare. You are not left on your own at the moment it matters most.
