Trying to work out what your extension or loft conversion could cost?

In the very early stages, broad cost metrics can give you a helpful starting point before you move into detailed design and builder conversations.

They’re not exact figures, but they can help you understand what might be realistic for your home.

This is exactly what we aim for at Design Spec - being there for our clients through every stage of their project.

From the initial planning and design phase to structural drawings, builder recommendations, kitchen designers and all the details in between, we help bring everything together so the process feels clearer, smoother and more manageable.

We’re so grateful for kind words like this and to be part of our clients’ home journeys.

A great design needs the right team behind the build.

We know how important it is to feel confident when choosing a builder. That’s why we work with a range of trusted builders we can refer you to, helping you take the next step with more clarity and support.

It’s not just about getting the design approved - it’s about supporting you as you move into the build stage, helping the process feel clearer, more organised and less overwhelming.

Because when you have the right people around you, the whole process feels easier to navigate.

At Design Spec, we look after the structural engineering in-house by working closely with our trusted structural engineering team throughout the process.

From your design drawings through to the technical details, we help manage everything under one roof, keeping the process clear, coordinated and simple for you.

It’s all part of making your project feel smoother from start to finish.

The first design is rarely the final design - and that’s exactly why our process includes an unlimited design stage.

At Design Spec, we provide preliminary design drawings for your approval, giving you the chance to review, tweak and refine the layout until it works for you.

Because every home, family and lifestyle is different.

Whether it’s changing the flow, adjusting the space, rethinking the layout or making the design feel more “you” - this stage is all about getting it right before moving forward.

The kitchen is no longer just a place to cook.

It’s where you host, work, catch up, entertain, help the kids with homework, gather as a family and spend so much of everyday life.

That’s why kitchen design needs to be functional, sociable and considered from the start.

A well-planned island can completely change how the space works - creating a place to prep, serve, sit, chat and bring everyone together.

A kitchen should look considered, but more importantly, it should work for the way you actually live.

Bank Holiday sunshine, doors open, BBQ on… this is summer family living ☀️

A strong indoor-outdoor flow can completely change how your home feels - giving children more space to play, making hosting easier, and helping everyday family life feel more connected.

And when glazing is part of the vision, we can connect you with trusted specialists to help bring it to life.
