Architectural Plans for Tropical Homes: Riviera Maya Design Guide

Updated August 2026 • By Recrea Construction • 6 min read

Clients arriving with plans drawn elsewhere usually have three of the drawings they need. They have floor plans, elevations and a nice render. What is missing is the set of drawings that resolve how a building actually keeps water out, how it is shaded, how the services reach where they need to be, and what every material is — and those are the drawings that determine whether the house is built the way it was imagined or improvised on site.

This describes what a complete architectural set contains for a house in this climate, why each drawing exists, the specific details that tropical construction requires and temperate detailing omits, and how the set relates to the engineering and the permit file.

The Drawings, and Why Each One Exists

• Site plan — the lot with setbacks, the building footprint, levels, drainage falls, the access, the plant positions (cistern, treatment plant, LP tank, pool equipment, AC condensers) and the trees being retained. This is the drawing the municipality reads against COS and setbacks, and the one that proves the plant actually fits somewhere.
• Floor plans with dimensions, door and window references, floor levels and finishes, and — here specifically — the position of every threshold that is flush, because each of those needs a drainage detail.
• Roof plan. The most neglected drawing and one of the most important: falls, outlets, overflows, parapet lines, the waterproofing extents, and the positions of anything that penetrates the roof. A roof plan that does not show falls and outlets is a leak waiting to be built.
• Elevations, with materials and finish notes, and the shading devices drawn rather than implied.
• Sections — and enough of them. Sections are where overhang depth against sun angle, ceiling height, roof build-up, threshold levels and the relationship between inside and terrace are actually resolved.
• Reflected ceiling plan, with lighting, fans, AC diffusers and access panels coordinated so the ceiling can be built once.
• Wet-area drawings: bathroom and kitchen layouts with tiling setting-out, waterproofing extents and fixture positions.
• Door and window schedule, with the glazing specification, frame finish and hardware grade per opening — on this coast that means stating laminated versus tempered, thermal break, anodised or marine powder coat, and 316 hardware.
• Finish schedule, room by room, so nothing is decided by a site conversation.
• Details — the drawings that separate a set from a sketch. See below.

The Details a Tropical House Needs

These are the details that imported plan sets typically do not contain, and every one of them addresses a failure we are called to repair on houses built without them.

• Flush threshold detail: channel drain, slope away, drained and vented sill behind the frame, and the membrane upstand. Without it, a flush threshold is a funnel.
• Window head, jamb and sill details showing the anchorage into structure, the sealant joint over a backer rod, the drip at the head and the drained sill. Driven rain here tests every one of those.
• Parapet and roof edge: coping, drip, membrane termination and upstand height — the detail that stops water running back under the coping and streaking the facade.
• Roof build-up with insulation, screed to falls, membrane, protection and finish, and the outlet and overflow details.
• Terrace over occupied space: full build-up including drainage layer and pedestal or bedding, plus every penetration detailed individually.
• Wet-area waterproofing: membrane extents, upstands, the shower floor detail and the junction with the door threshold.
• Overhang and shading sections drawn against actual sun angles for this latitude — an overhang copied from a temperate detail is either useless or blocks the view for no benefit.
• Movement joints in large render and concrete planes, positioned deliberately.
• Termite barrier detail at slab penetrations and any timber-to-structure junction.
• Plant room layouts with clearances that allow equipment to be serviced and replaced.

Coordination, the Permit File, and What It Costs

The architectural set does not stand alone. It has to agree with the structural design (which depends on the soil study), the MEP design (which puts conduit, sleeves and drainage in the slab before it is poured), and the permit file. The coordination points that cause the most trouble when they are missed: sleeves and penetrations through beams and slabs; the drainage invert levels against the treatment plant position; electrical riser and panel positions against the architecture; AC equipment positions and condensate routes; and structural depths against ceiling heights, which is the one that most often forces a late compromise.

For the municipal file, the set is signed by the DRO and submitted alongside the structural and installation designs, the soil study and the environmental resolution where required. Drawings that are beautiful but incomplete come back — a submission missing the installations or the roof drainage is a submission that generates a request for information and loses weeks.

If you already have plans, what we do is a review rather than a redraw: check the design against the land-use envelope (COS, CUS, height, setbacks), against the climate issues (orientation, west exposure, cross-ventilation, terrace depth), and against the local service spaces that imported sets omit — then add the details and schedules the set is missing and produce the engineering. That is usually far cheaper than starting again, and it keeps the design you fell in love with while making it buildable here.
