For architects and building designers

The right home solution, made clear.

retain.solutions helps you show clients four real pathways for an existing home (retain, retrofit, extend or replace), compared on cost, carbon, comfort and time.

Four pathways. Real numbers.
A clearer conversation.

RetainKeep what works.
RetrofitMore comfort, less energy.
ExtendGrow with your needs.
ReplaceWhen it's the right call.

The conversation

"Should we knock it down?"

Most clients arrive with an answer already in mind. Often it's demolish and start again, before the alternatives have been properly weighed.

Making the case for the right pathway usually comes down to your persuasiveness and back-of-envelope numbers, rebuilt from scratch for every project, under fee pressure.

retain.solutions gives you a fast, defensible starting point for that conversation, so your expertise goes where it matters.

Four pathways

Every option, side by side.

Each pathway is laid out with what it typically costs, saves and changes, so you and your client can choose with clear eyes.

Retain

Keep what works. Refresh for what's next.

A cosmetic and functional refresh: re-organising rooms and zones, paint, floors, a kitchen or bathroom. No changes to the building envelope.

Retrofit

Improve performance. More comfort, less energy.

Insulation, draught sealing, glazing, ventilation and electrification, without adding floor area.

Extend

Add space. Grow with your needs.

Keep the existing structure and add to it: a rear addition, a second storey, a retained footprint plus more.

Replace

A fresh start. When it's the right call.

Demolish and rebuild, with a fully new, compliant home and no legacy building issues.

An honest comparison.

retain.solutions starts from the building that's already there, but it isn't built to keep everything. When a home is beyond saving, or replacing it is the better outcome for the people who live in it, we'll say so. The aim isn't a particular answer. It's the right one, made clear.
