Outdoor Living Builder in Columbia, MD

Why Columbia homeowners hire Custom Design & Build

Columbia is a planned community of ten villages founded in 1967. Exterior changes in most villages need Columbia Association architectural committee approval before work starts, and we handle that review as part of design.

Near: Lake Kittamaqundi, Merriweather Post Pavilion, Symphony Woods.

We're MHIC #91686-licensed, Trex Pro Platinum, an authorized Sunspace dealer, and Azenco-certified for motorized louvered pergolas. Every Columbia project is custom-designed, permitted, and built end-to-end by our own crews. No subcontracted middlemen.

Services we build in Columbia

Custom decks in Columbia

Columbia decks come with a step other towns do not have. Most of the ten villages require Columbia Association architectural committee approval before exterior work starts, and we file that review as part of design rather than discovering it late. Around Lake Kittamaqundi and Symphony Woods, mature trees and shared open space affect where the deck can sit. Howard County requires a building permit for any deck attached to the home, with frost protection 30 inches deep, and we follow the county's Typical Deck Details guide. Our own crews build wood and Trex composite decks under MHIC #91686.

Custom pergolas in Columbia

In Columbia, a pergola is an exterior change, which means Columbia Association architectural committee approval in most villages before work starts. We file that review with the design so it runs alongside the county process. Around Lake Kittamaqundi and Merriweather Post Pavilion, shared open space and mature trees affect where posts can go. Howard County requires a permit for a pergola attached to the home. We build wood pergolas and install certified Azenco aluminum systems with our own crews. MHIC #91686.

Sunrooms in Columbia

A sunroom is one of the most visible exterior changes you can make, which in Columbia means Columbia Association architectural committee approval in most villages before work begins. We file that review as part of design so it does not surprise you later. Around Lake Kittamaqundi and Symphony Woods, tree cover and shared open space affect orientation and roof tie-in. As an authorized Sunspace dealer we install three-season and year-round insulated rooms, built by our own crews with the Howard County permit handled here. MHIC #91686.
