// Description
Magalhaes building, lo cated in the neighbo rho o d o f Po ble Sec o f Barcelo na and designed by Betarq Gro up, SLP, has 450 m2.
With 3 flo o rs (gro und, first and seco nd with walkable terrace o n the ro o f). It co nsists o f a to tal o f 6 apartments with surfaces
ranging fro m 40 to 70 m, with o ne o r two bedro o ms. The building, co rnerback, has two facades and two medians. It is made
with light frame structure o f wo o d (Surro und System Arquima). It was decided to maintain the facades o f the gro und flo o r, so lid
brick fro m 18 9 0 , being the rest o f the building newly built. Larch wo o d natural, witho ut sapwo o d, has been the material o f
cho ice fo r lining the facade, while the exterio r carpentry is wo o d Iro ko . The building is built o n sustainability criteria and is
certified by the Green Building Co uncil Spain with a very high rating (4 leaves). The main inno vatio n refers to the mo dular
co nstructio n system o f prefabricated wo o d, where mo st o f the materials used are lo cal with a lo w enviro nmental impact. This
co nstructio n system limits the amo unt o f lo o se material and accelerates the co nstructio n phase. Furthermo re, when the life o f
the building ends, it will allo w quickly dismantled and reuse its parts. On the o ther hand, the thermal insulatio n system is so
efficient that mo st o f the year it is no t necessary to use mechanical air co nditio ning systems.

Dé m arche dé ve lo ppe m e nt durable du m aît re d'o uvrage : Valuiz Invest is a co mpany that aims at the co nstructio n
and / o r rehabilitatio n o f buildings to start an eco no mic activity within the wo rld o f emo tio ns, to urism and leisure, using them
as a generato rs vehicle to sensatio ns: pensio ns, to urist apartments o r o ther o ptio ns, but always with eco lo gical, so cial and
eco no mic respo nsibility. Valuiz Invest is a so ciety and as such its o bjective is to generate a pro fit and we have to be pro fitable,
but pro fitability to day is no lo nger o ur so le co ncern. We have o ther prio rities like the ratio nal use o f natural reso urces,
particularly water and energy and that means co nsuming less during use and cause less enviro nmental impact during
co nstructio n o r rehabilitatio n and even deco nstructio n. We are co nvinced that thanks to sustainability we can reduce co sts and
increase revenue. It is true that the pro cess requires reo rganizing management mo dels, techno lo gies and pro cesses, but here
is where we have the future.
De script io n archit e ct urale : Ho mes are intended to be a perfect suit fo r its o ccupants. They sho uld be able to live
co mfo rtably, in a way that makes them feel go o d witho ut kno wing why.
The ho mes try to teach their o ccupants, make them reflect them o n the value o f things, things made with interest and respect,
o n the value o f simplicity to acco mpany o ur pro jects and actio ns. Ho mes sho uld enable its inhabitant to have the feeling o f
being in place, no t wanting to be so mewhere else, o f being at ease with themselves.
We turn no w to the analysis o f the building o n its co re co nstructio n elements. First, to say that fo r the realizatio n o f the
structure, flo o rs, facades and interio r partitio ns has o pted fo r light frame structure o f wo o d, specifically with SEA (Arquima
Surro und System) system.
Fo r the fo undatio n o f the building has been justified and maintained the existing two and the two dividing walls and made
co rrespo nding to the intermediate wall and aro und the elevato r by micro piling.
If we go into the ho mes we have so ught maximum co mfo rt. Distributio ns witho ut hallways, ceilings and bare wo o d flo o rs, lo w
windo ws, preferences fo r whites and lumino us spaces, have so ught to harmo nize the o ccupant and into equilibrium with the
materials and natural light. The night lighting is designed to o ffer a relaxing and warm atmo sphere.

The pro perty accepted the no vel pro po sed so lutio n successfully and the result has been very go o d fo r the develo per o f the
building. The prefabricated façade was installed by the co mpany that manufactures and the building was "mo unted"; in just 9
days. Users are very satisfied with the so lutio n by its finish and co mfo rt in every way.

// Environnement urbain
Enviro nne m e nt urbain : The building, co rnerback, has two facades and two medians and, altho ugh it is no t a listed
building (no architectural interest by the administratio n), it was decided to maintain the facades o f the gro und flo o r, so lid brick
6 0 cm thick , dating fro m 18 9 0 . Fro m the beginning we were interested to maintain, despite no t being catalo ged, the o riginal
gro und flo o r facades, as mentio ned abo ve, are fro m the late nineteenth century. The reaso ns which led us to this were: On the
o ne hand, it seemed respectful and affectio nate with the neighbo rho o d to keep so me o f its memo ry depo sited in this building,
which remains beyo nd the co nstant changes. Well, fro m o ur co nsideratio n, the value o f the memo ry o f peo ple is independent
o f the value o f things established by the institutio ns. On the o ther hand, fro m the standpo int o f durability and maintenance o f
the materials, it seemed co nsistent to keep this strip o f gro und flo o r, in o rder to pro tect the fragile wo o d fro m the pedestrian
area. Ano ther reaso n, in this directio n, refers to the co mpo sitio nal fact and also to play and dialo gue between the materials. In
the area there are public transpo rtatio n, several bus lines and subway two blo cks fro m the building. There are sho ps in mo st
o f the gro und flo o rs o f the surro unding buildings. A few streets have an impo rtant cultural co mplex, which co ntains the Theatre
Institute, the flo wer market, the theater Lliure Mo ntjuic and the Museum o f Archaeo lo gy o f Catalo nia.
