Flores & Prats Inventory the Building Before They Change It

The Barcelona studio's contribution to adaptive reuse is a method, not a look: draw and model every found element first, then compose the new building from the old one's own parts.

The Repointing Joint Must Stay Weaker Than the Brick, Not Stronger

Repointing a historic wall with hard cement mortar looks like a repair and behaves like a slow demolition. The durable joint is the weak, breathable one, and the mechanism explains why.

The New Structure Carries Itself: How Lacaton & Vassal Enlarge Social Housing Without Emptying It

The French duo who won the 2021 Pritzker do not renovate a facade so much as build a second, self-supporting one in front of it — an unheated winter garden that hands each flat tens of square metres while the tenants never move out.

The Drain Is the Waterproofing, Not the Membrane

Barrier tanking asks one unbroken layer to hold back the water table and fails invisibly the moment it is breached. A Type C cavity-drain system does the opposite, and BS 8102 puts the habitable grade in the sump and pump, not the plastic.

Insulate a Solid Wall from Inside and It Must Breathe, Not Seal

On a pre-1919 solid wall, internal insulation makes the masonry colder and slower to dry and buries the dew point inside it — so only vapour-open, capillary-active materials keep the wall, and its hidden joist ends, from rotting.

The Air Gap, Not the Glass: Why Secondary Glazing Beats Replacing a Heritage Window

Secondary glazing keeps a period window in place and still beats a sealed replacement on noise, because a wide, open air cavity between two decoupled panes is a better acoustic and thermal spring than a hermetic 16mm unit, and that same unsealed cavity is what keeps the change reversible.

The Millimetres Decide: Why Retrofit Underfloor Heating Is a Build-Up Problem, Not a Heat Problem

In a renovation, underfloor heating is chosen by the millimetres a fixed ceiling can spare and by the floor you already have, while its real payoff is the low flow temperature a heat pump craves.

Count the Door: Why the Swing Is a Small Room's Biggest Waste of Floor

A hinged door sterilizes almost six square feet of floor no furniture can use. In a compact home, choosing the right slider, or keeping the swing only where its arc is already empty, is often the single biggest space you can reclaim.

Measure the Slab, Not the Floor: When a Sleeping Mezzanine Actually Frees a Small Home

A sleeping mezzanine is the highest-yield move in a compact home — but only when the height to the real slab clears the full stack of headroom, structure and mattress. Here is the section math that decides it.

Built Below the Tile: Why the 2026 Wet Room Lives or Dies on the Membrane and the Fall

The seamless, curbless bathroom is 2026's benchmark layout, but its spa calm depends on a continuous waterproofing membrane and a floor fall you never notice, not on the microcement or tile on top.
