Building an extension is a big investment – emotionally, financially, and practically. You want the result to be exactly what you’ve pictured, but sometimes homeowners feel their vision gets “lost in translation” between architects and builders.
The truth is, when architects and builders work in harmony with you, the results can be spectacular. At Reltic Extend, we combine design and build under one roof, meaning you don’t need to juggle separate professionals. In this guide, we’ll explain how to work effectively with your team so you get the home you’ve always dreamed of.
Why Collaboration Matters
A home extension is a team effort. Architects bring creativity and design flair, while builders bring practical knowledge and construction expertise. When both work together seamlessly, you gain:
Design that’s both beautiful and buildable – no wasted money on ideas that can’t be constructed.
Better cost control – realistic pricing from the start.
Fewer delays – smooth communication avoids missteps.
A stress-free journey – you’re supported every step of the way.

Step 1: Define Your Vision Early
Before meeting your architect or builder, think carefully about:
Your must-haves (kitchen island, skylights, garden access),
Your lifestyle (entertaining, family hub, quiet retreat),
Your budget range.
Clear goals help professionals deliver exactly what you want. Our How We Work page shows how we turn homeowner visions into structured plans.
Step 2: Choose the Right Professionals
Not all architects and builders work the same way. When choosing who to work with, look for:
A proven track record in Rear Extensions, Side Extensions, or similar projects,
Transparent communication about costs and timelines,
A design and build service that combines both disciplines.
With Reltic Extend, you don’t need to coordinate multiple professionals – we handle everything in-house.
Step 3: Keep Communication Open
Misunderstandings cause delays and overspending. To avoid this:
Ask for regular updates,
Keep a written record of design choices and agreements,
Use visual tools like 3D designs to check ideas match your vision.
We provide a transparent approach so you’re never left guessing.
Step 4: Balance Creativity and Practicality
Sometimes architects propose bold ideas, while builders push for what’s practical. The sweet spot lies in balance.
Don’t be afraid to dream big – but ask how it will work structurally.
Be open to compromise if a design element risks overspending.
Use experienced teams who can bridge design with construction.

Step 5: Manage Budgets Together
One of the biggest frustrations for homeowners is when the final build costs much more than expected. Avoid this by:
Asking for cost input during design,
Using a clear payment structure,
Keeping contingency funds ready.
Our Cost Calculator helps you set realistic expectations from day one.
Step 6: Plan for Permissions and Approvals
Architects usually prepare drawings for planning, but builders understand how local councils interpret rules in practice. Working together, they ensure your application succeeds.
Our Planning page explains how we simplify the process, combining design with practical approval strategies.
Step 7: Trust the Process
Home extensions are exciting, but they can also feel stressful. Trusting your professional team makes the journey smoother.

A unified vision from sketch to completion,
